 Here are some of the factors affecting photosynthesis. Light Intensity: An increased light intensity leads to a high rate of photosynthesis and a low light intensity would mean low rate of photosynthesis. Concentration of CO 2: Higher carbon dioxide concentration increases the rate of photosynthesis. Normally the carbon dioxide concentration of 0.03 to 0.04 percent is sufficient for photosynthesis. Temperature: An efficient photosynthesis requires an optimum temperature range between 25 to 35 o C.
Water: Water is an essential factor for photosynthesis. The lack of water also leads to a problem for carbon dioxide intake.

 Light
As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis. At higher light intensities (plateau of graph), further increasing the light intensity does not increase the rate of photosynthesis meaning that another factor is limiting photosynthesis. On a hot day, photosynthesis happens at a higher rate when compared to the cooler day, showing that temperature has an effect and is the limiting factor on a cooler day. An increased level of carbon dioxide leads to a higher rate of photosynthesis when compared to the lower carbon dioxide level. This shows that the carbon dioxide level has an effect and is now limiting the rate of photosynthesis. Carbon dioxide
As carbon dioxide concentrations increase, so too does the rate of photosynthesis until a certain point where the graph levels off. At lower carbon dioxide concentrations carbon dioxide is the limiting factor because an increase in carbon dioxide causes an increase in photosynthesis. At higher carbon dioxide concentrations (plateau of graph), further increasing the carbon dioxide concentration does not increase the rate of photosynthesis meaning another factor is limiting photosynthesis. Temperature
Temperature affects all reactions because an increase in temperature causes the molecules involved to gain kinetic energy and therefore react more frequently.

The Rate of Photosynthesis
Want to learn more about Photosynthesis?
 Chlorophyll concentration - High chlorophyll concentration gives a high rate of photosynthesis. Light intensity - Increasing light intensity increases the rate of photosynthesis because more energy is provided. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor (such as temperature) is limiting the rate of the reaction. Carbon dioxide concentration - Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis. However, above a certain threshold, further increases in the carbon dioxide concentration do not increase the rate of photosynthesis because another factor (such as light intensity) is limiting the rate of reaction. Temperature - Increasing the temperature increases the rate of photosynthesis because more energy is provided. However, if the temperature is increased to above about 45°C, the enzymes that catalyse (speed-up) the reaction begin to denature (not work anymore). This causes the rate of the reaction to drop sharply until it stops altogether. Initially, increasing temperature increases the rate of photosynthesis, as more energy is provided. Above a certain temperature (about 45 degrees Celsius), the enzymes involved in the reaction begin to denature and, consequently, the rate of the reaction begins to drop sharply until it stops altogether.

Photosynthesis
Photosynthesis takes place inside chloroplasts found in plants and algae. The reaction is endothermic, meaning that it requires energy. The source of this energy is sunlight, which is trapped by a chemical called chlorophyll inside chloroplasts in plant cells. During photosynthesis, carbon dioxide reacts with water to produce glucose and oxygen. The Rate of Photosynthesis
The four key factors affecting the rate of photosynthesis are: Chlorophyll concentration - High chlorophyll concentration gives a high rate of photosynthesis. Light intensity - Increasing light intensity increases the rate of photosynthesis because more energy is provided. However, if the light intensity is increased above a certain threshold, the rate of photosynthesis will not increase because another factor (such as temperature) is limiting the rate of the reaction. Carbon dioxide concentration - Increasing the carbon dioxide concentration increases the rate of photosynthesis because carbon dioxide is a reactant in photosynthesis.

 It is difficult to do this out in the open air but is possible in a greenhouse. The rate of photosynthesis increases linearly with increasing carbon dioxide concentration (from point A to B on the graph). Gradually the rate falls of and at a certain carbon dioxide concentration the rate of photosynthesis stays constant (from point B to C on the graph). Here a rise in carbon dioxide levels has no affect on the rate of photosynthesis as the other factors such as light intensity become limiting. Many crops such as tomatoes and lettuce give higher yield when grown in greenhouses. Farmers add additional carbon dioxide into the greenhouse to increase the concentration and so the rate of photosynthesis of the crops. The additional cost of the carbon dioxide is worthwhile because of the increased yield. Some companies have used this to great environmental use. Rather than pump waste carbon dioxide into the atmosphere as a pollutant they redirect it into big greenhouses where plants such as tomatoes use it during photosynthesis. This not only reduces their carbon footprint but gives an additional profitable product.

It is useful to be able to interpret a graph like the example below. This graph shows the effect of light intensity on the rate of photosynthesis at two different carbon dioxide concentrations. Light intensity is limiting the rate of photosynthesis at light intensities of 0 to 3.75 units. As light intensity is increased the rate of photosynthesis increases. At light intensities of 3.75 to 5.5, a carbon dioxide concentration of 0.03 per cent is insufficient and limits the rate of photosynthesis. A carbon dioxide concentration of 0.1 per cent is sufficient and the rate of photosynthesis continues to increase as light intensity increases. At light intensities of 5.5 units and above, a carbon dioxide concentration of 0.1 per cent is limiting and the rate of photosynthesis does not increase even when light intensity is increased. Light intensity is not limiting the rate of photosynthesis at light intensities of five to eight units. As light intensity is increased the rate of photosynthesis remains the same. At light intensities of five to eight units carbon dioxide concentration is limiting the rate of photosynthesis.

photosynthesis increases and visa versa. · Water supply- if a plant cannot absorb enough water, then the rate
of photosynthesis decreases. · Carbon dioxide concentration- if the percentage of carbon dioxide in
the atmosphere increases, so does the rate of photosynthesis. · Temperature- if the temperature increases, then the rate of
photosynthesis also increases, (however, temperatures above 40OC can
damage a plant and photosynthesis stops because the chlorophyll gets
too hot). The factor I will be investigating is light intensity; how it affects
the rate of photosynthesis. The factors I will be keeping constant are: · Water supply- by using same millimetre of water each time. · Temperature- by using a thermometer to make sure the water is at the
temperature each time. · Carbon dioxide- by not adding any thing in the water which increase
the carbon dioxide level, such as Hydrogen carbonate.

3.8.4 Outline the differences in absorption of red, blue and green light by chlorophyll.
3.8.5 State that light energy is used to produce ATP, and to split water molecules (photolysis) to form oxygen and hydrogen.
3.8.6 State that ATP and hydrogen (derived from the photolysis of water) are used to fix carbon dioxide to make organic molecules.
3.8.7 Explain that the rate of photosynthesis can be measured directly by the production of oxygen or the uptake of carbon dioxide, or indirectly by an increase in biomass.
3.8.8 Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis.
 3.8.8 Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis. As temperature increases, the rate of photosynthesis increases more and more steeply until the optimum temperature is reached. If temperature keeps increasing above the optimum temperature then photosynthesis starts to decrease very rapidly. As light intensity increases so does photosynthesis until a certain point. At a high light intensities photosynthesis reaches a plateau and so does not increase any more. At low and medium light intensity the rate of photosynthesis is directly proportional to the light intensity. As the carbon dioxide concentration increases so does the rate of photosynthesis. There is no photosynthesis at very low levels of carbon dioxide and at high levels the rate reaches a plateau.

 The light that is absorbed the best is blue, so this shows the highest rate of photosynthesis, after which comes red light. Green light cannot be absorbed by the plant, and thus cannot be used for photosynthesis. Chlorophyll looks green because it absorbs red and blue light, making these colours unavailable to be seen by our eyes. It is the green light which is not absorbed that finally reaches our eyes, making the chlorophyll appear green. Factors affecting Photosynthesis
For a constant rate of photosynthesis, various factors are needed at an optimum level. Here are some of the factors affecting photosynthesis. Light Intensity: An increased light intensity leads to a high rate of photosynthesis and a low light intensity would mean low rate of photosynthesis. Concentration of CO 2: Higher carbon dioxide concentration increases the rate of photosynthesis.

The process of photosynthesis can be affected by a number of factors. These include: 1. Light Intensity
The amount of light reaching the plant’s leaf has a significant impact on the rate by which it creates food. In general, the higher the light intensity, the higher the rate of photosynthesis by plants. On the flip side, when light intensity is low, the rate of photosynthesis will also decline.

If the light intensity is kept the same, and the carbon dioxide concentration is increased from 0.03 per cent to 0.10 per cent then the rate of photosynthesis increases. previous

Carbon dioxide is needed in the dark reaction as a raw material used in the synthesis of glucose. As carbon dioxide concentration increases, the rate of photosynthesis increases. At high concentrations, the rate of photosynthesis begins to level out due to factors not related to carbon dioxide concentration. One reason might be that some of the enzymes of photosynthesis are working at their maximum rate. In general, carbon dioxide is found in low concentration in the atmosphere, and so atmospheric carbon dioxide levels may be a major limiting factor on photosynthesis when at low levels. ...Show more

What is Photosynthesis? How It Occurs? - SCIENCE & BIOLOGY
 Light intensity
As light intensity increases, so does the rate of photosynthesis. This occurs until it reaches a point where, no matter how much light is available, the rate of photosynthesis will increase no more. There could be the light of a million suns shining on that plant but photosynthesis cannot go faster once this point is reached. This is because something else, such as CO2 concentration, water availability or temperature could be limiting the rate. Often with high light intensity (strong light) comes higher temperatures. CO2 Concentration
As the concentration of carbon dioxide increases, so does the rate of photosynthesis. This occurs until it reaches a point where, no matter how much carbon dioxide is available, the rate will increase no more. There could be all the carbon dioxide in the world available to the plant but photosynthesis cannot go faster. This is because something else, such as light intensity, temperature or water availability, could be limiting the rate. Or it could be that all the enzymes are working at maximum speed and can't work any faster!

 This investigation will be focusing on which wavelengths of visible light, colour of light, has the highest rate of photosynthesis. It is safe to assume that green would have to lowest rate of photosynthesis because it is reflected by the leaves of plants and red/violet would have the highest rate of photosynthesis. Hypothesis: I hypothesise that the rate of photosynthesis will be less for the green light whereas lights such as red and violet will have the fastest rate of photosynthesis. Variables: Variable Type
Variable
How it is controlled/Managed
Why it is controlled/Manage
Independent
Colour/Wavelength of light
I will change the colour of the light using 5 different colours including white light
To determine how the wavelength of light affects the rate of photosynthesis the most
Dependent
The rate the Cabomba flower synthesises
N/A
N/A
Control
Light intensity
The bulb will be kept at 5cm away from the test tube containing the Cabomba flower at all times
Keeping the light intensity the same means it will have no additional effect on the rate of photosynthesis. A change of light intensity would result in a change of photosynthesis rate. Control
Room temperature ºC
The room temperature will be kept the same for the duration of the investigation of the experiment by ensuring there are no windows open, air conditioners on or heaters being used
By doing so I will be able to keep the room temperature relatively the same throughout the experiment reducing the effect of temperature increase or decrease on the rate of photosynthesis. Control
Light bulb
The same 100W light bulb will be used throughout the investigation
Different light bulbs may have different light intensities therefore using the same light bulb eradicates the issue of dealing with different light intensities that could affect the rate of reaction
Control
Concentration of Sodium Hydrogen Carbonate (NaHCO 3 )
Ensuring the same concentration of NaHCO 3 is used in the experiment and the source remains the same
Concentrations of Sodium Hydrogen Carbonate could have an effect on the rate of photosynthesis as it provides necessary carbon dioxide for photosynthesis so keeping the concentration the same eradicate that issue
Control
Type of leaves and size
The same sample of plant will be used throughout the duration of the experiment
Different plants may photosynthesise at different rates and different sized samples may also affect the rate of photosynthesis. Different leaves on plants absorb a different number of visible light wavelengths resulting in a different rate of photosynthesis.

IB Biology Notes - 3.8 Photosynthesis Photosynthesis
Photosynthesis
3.8.1 State that photosynthesis involves the conversion of light energy into chemical energy.
3.8.2 State that light from the Sun is composed of a range of wavelengths (colours).
3.8.3 State that chlorophyll is the main photosynthetic pigment.
3.8.4 Outline the differences in absorption of red, blue and green light by chlorophyll.
3.8.5 State that light energy is used to produce ATP, and to split water molecules (photolysis) to form oxygen and hydrogen.
3.8.6 State that ATP and hydrogen (derived from the photolysis of water) are used to fix carbon dioxide to make organic molecules.
3.8.7 Explain that the rate of photosynthesis can be measured directly by the production of oxygen or the uptake of carbon dioxide, or indirectly by an increase in biomass.
3.8.8 Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis.
 For example, aquatic plants release oxygen bubbles during photosynthesis and so these can be collected and measured. The uptake of carbon dioxide is more difficult to measure so it is usually done indirectly. When carbon dioxide is absorbed from water the pH of the water rises and so this can be measured with pH indicators or pH meters. Finally, photosynthesis can be measured through an increase in biomass. If batches of plants are harvested at a series of times and the biomass of these batches is calculated, the rate increase in biomass gives an indirect measure of the rate of photosynthesis in the plants. 3.8.8 Outline the effects of temperature, light intensity and carbon dioxide concentration on the rate of photosynthesis. As temperature increases, the rate of photosynthesis increases more and more steeply until the optimum temperature is reached. If temperature keeps increasing above the optimum temperature then photosynthesis starts to decrease very rapidly. As light intensity increases so does photosynthesis until a certain point. At a high light intensities photosynthesis reaches a plateau and so does not increase any more.

 Graph Of How Light Affects The Rate Of Photosynthesis
Light
When we discuss light as a factor that affects photosynthesis we try to  differentiate it into three parts namely light intensity, light quality and  the duration of exposure to light. There is a linear relationship between  incident light and CO2 fixation rates at low intensities. At higher  intensities the rate does not keep increasing exponentially because the  other factors such as water, CO2 concentration and temperature limit the  rate gradually. It is interesting to know that light saturation occurs at 10 per cent of  the full sunlight. What this means as a factor for photosynthesis is that  light is rarely a limiting factor only exceptions being the plants that  stand in shade or plants in thick forests. Trees in those forests need to  compete each other for available resources just like in a normal population  of humans. Increase in incident light beyond a point results in the decrease of  photosynthesis due to the breakdown of chlorophyll. Carbon Dioxide Concentration
The major limiting factor for photosynthesis is Carbon Dioxide (CO2). As  the carbon dioxide concentration is very low in the atmosphere. In  percentage terms it can be put somewhere between 0.03 to 0.04 per  cent.

 The chemical reaction also produces oxygen, which is released back into the atmosphere. Plants get carbon dioxide from the air, water through their roots, and energy from sunlight. We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration. However, once light intensity and carbon dioxide concentration reach a certain level, photosynthesis rates level off and don't increase much further. In terms of temperature, plants will have an optimum temperature at which the photosynthesis rates are highest. If it's too hot or too cold, photosynthesis is slower. We also learned that water isn't considered a limiting factor, since when water levels drop, plants close their stomata, which are tiny pores on the outer, skin-like surface of plants that control gas exchange. In addition, if there was no water, plants in the area would die and photosynthesis wouldn't take place anyway. It's important to consider the aforementioned factors that impact photosynthesis, since they are all part of the ecosystem that keeps humans alive!

 On the other hand, low light intensity results in a lower rate of photosynthesis. The concentration of CO2: Higher concentration of carbon dioxide helps in increasing the rate of photosynthesis. Usually, carbon dioxide in the range of 300 – 400 PPM is adequate for photosynthesis. Temperature: For efficient execution of photosynthesis, it is important to have a temperature range between 25° to 35° C.
Water: As water is an important factor in photosynthesis, its deficiency can lead to problems in the intake of carbon dioxide. The scarcity of water leads to the refusal of stomatal opening to retain the amount of water they have stored inside. Pollution: Industrial pollutants and other particulates may settle on the leaf surface.

For example, on bright sunny days the carbon dioxide concentration of the atmosphere is usually the limiting factor, not light intensity. However, on cloudy days light may be the limiting factor. Heinicke and Childers (1937) have found that the rate of photosynthesis steadily increased with light intensity up to about full sunlight even through saturation intensity for a single exposed leaf would be sufficiently lower. The need for higher light intensities for maximum photosynthesis of an entire tree is due to partial illumination of the inner leaves. ADVERTISEMENTS: Both quality and intensity of light influence photosynthesis. Light between wavelength of 400 nm and 700 nm is most effective, for photosynthesis. This light is called photosynthetically active radiation (PAR).

At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature. Carbon dioxide concentration
Carbon dioxide – with water – is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. Again, at some point, a different factor may become limiting. Beyond this concentration, further increases in the concentration of carbon dioxide will not result in a faster rate of photosynthesis, and would appear on a graph as a horizontal line. Temperature
The chemical reactions that combine carbon dioxide and water to produce glucose are controlled by enzymes. As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of molecular collisions between enzymes and substrates.

 The walls of palisade and spongy parenchyma possess water. Carbon dioxide dissolves in water and ultimately passes through the walls in aqueous solution. Carbon Dioxide Concentration: If light intensity and temperature are favourable, the carbon dioxide of the atmosphere limits the rate of photosynthesis. The workers like Kreuslar (1887), Brown and Escombe (1902) and Pantanelli (1903) investigated that there is an increase in the rate of photosynthesis with an increase in the concentration of carbon dioxide at the lower levels of carbon dioxide concentrations. A decline in rate was observed in higher concentrations. Blackman and his co-workers claimed that after an optimum concentration is reached, the rate of photosynthesis remains constant over a wide range of carbon dioxide concentrations. ADVERTISEMENTS: It has been demonstrated experimentally that at usual temperature and light intensities, artificial increase of carbon dioxide up to a concentration of 0.5 per cent may give an increased rate of photosynthesis, but only for a limited period. It appears that the high level of carbon dioxide is injurious to plants.

Rate of photosynthesis
The rate of photosynthesis is affected by the following factors: concentration of carbon dioxide
availability of water
light intensity
The rate of photosynthesis is also affected by temperature because the reactions of photosynthesis are controlled by specific enzymes. At low temperatures photosynthesis happens more slowly. A limiting factor is a factor that can limit the rate of photosynthesis if it is in short supply. A greenhouse can be used to overcome the limiting factors of photosynthesis. This allows plants to grow faster as they are making more food. Greenhouses can have artificial light so that photosynthesis can continue beyond daylight hours, or at a higher than normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide as well as heat. previous

Factors affecting photosynthesis
There are several ways of measuring the rate of photosynthesis in the laboratory. These include: the rate of oxygen output
the rate of carbon dioxide uptake
the rate of carbohydrate (glucose) production
These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output. Several factors can affect the rate of photosynthesis: light intensity
carbon dioxide concentration
temperature
The amount of chlorophyll also affects the rate of photosynthesis: plants in lighting conditions unfavourable for photosynthesis synthesise more chlorophyll, to absorb the light required
the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise, such as downy mildew in grape vines
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. previous

At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature. Carbon dioxide concentration
Carbon dioxide – with water – is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase.

Limiting factors
The rate of photosynthesis depends on temperature and the availability of light and carbon dioxide. If photosynthesis is to happen at its maximum rate, all environmental factors must be present at the optimum levels. If one or more factors are in short supply, the rate of photosynthesis will be limited. These factors are then limiting factors and the rate of photosynthesis will be determined by the factor that is in shortest supply. Light
As light intensity increases so too does the rate of photosynthesis until a certain point where the graph levels off. At lower light intensities, light is the limiting factor because an increase in light causes an increase in photosynthesis. At higher light intensities (plateau of graph), further increasing the light intensity does not increase the rate of photosynthesis meaning that another factor is limiting photosynthesis. On a hot day, photosynthesis happens at a higher rate when compared to the cooler day, showing that temperature has an effect and is the limiting factor on a cooler day. An increased level of carbon dioxide leads to a higher rate of photosynthesis when compared to the lower carbon dioxide level.

Factors Impacting Photosynthesis
Light intensity is one factor that affects photosynthesis. Without the energy from light, the chemical reaction cannot happen. If plants have less light, they photosynthesize more slowly. The speed of photosynthesis increases with greater light intensity, though it ultimately levels off once the plant has as much light as it needs. Carbon dioxide concentration is another factor that affects photosynthesis. Generally, there is plenty of carbon dioxide in the air so there is little impact on photosynthesis in different environments. It's still a requirement, however, and if we deprive plants of carbon dioxide in the lab, we find a similar relationship to that of light: the rate of photosynthesis increases with carbon dioxide concentration until the plant has enough or more carbon dioxide than it needs; at that point, the rate doesn't increase much further. Based on the equation, it's probably not surprising that carbon dioxide and sunlight are two major factors that affect photosynthesis, but there is a third that isn't so obvious:

Michael states that a higher light intensity would increase the rate of photosynthesis, however, Reona disagrees. They both decide to test this theory out by conducting an experiment. Things to remember! When there is no light, photosynthesis can't occur since light is the activation energy needed for plants to convert carbon dioxide and water to glucose and oxygen
When there is no light, the plants would use up oxygen therefore emitting carbon dioxide bubbles instead. The plants should be given a couple minutes to start initiating the process of photosynthesis before you start timing. Graph

FAQs
 Apart from plants, photosynthesis is also found to occur in blue-green algae. What Happens During Photosynthesis
It involves a chemical reaction where water, carbon dioxide, chlorophyll, and solar energy are utilized as raw materials (inputs) to produce glucose, oxygen, and water (outputs). Photosynthesis Equation
Stages of the Process
Photosynthesis occurs in two stages: 1) The Light-dependent Reaction
Takes place in the thylakoid membranes of chloroplasts only during the day in the presence of sunlight
High-energy phosphate molecules adenosine triphosphate (ATP) and the reducing agent NADPH are produced with the help of electron transport chain
2) The Light-independent or Dark Reaction ( Calvin cycle)
Takes place in the stroma of chloroplast in the absence of light that helps to fix carbon
ATP and NADPH produced in the light reaction are utilized along with carbon dioxide to produce sugar in the form of glucose
Factors Affecting the Rate of Photosynthesis
Intensity of Light: The higher intensity of light increases the rate of photosynthesis
Temperature: Warmer the temperature, higher the rate of photosynthesis. The rate is highest between the temperatures of 25° to 35° C, after which it starts to decrease
Concentration of Carbon dioxide: Higher concentration of carbon dioxide increases the rate of photosynthesis until it reaches a certain point, beyond which no further effects are found
Although all the above factors together interact to affect the rate of photosynthesis, each of them individually is also capable of directly influencing the process without the other factors and thus called limiting factors. Importance of Photosynthesis
It serves two main purposes that are essential to support life on earth: Producing food for organisms that depend on others for their nutrition such as humans along with all other animals
Synthesizing oxygen by replacing carbon dioxide in the atmosphere

Under these conditions, if a plant is supplied with only one 1 mg of carbon dioxide, the rate of photosynthesis would be limited by carbon dioxide (because concentration of carbon dioxide is less than what can be assimilated in the available intensity of light). Now if the carbon dioxide concentration is gradually increased, the rate of photosynthesis will also increase correspondingly until the assimilation rate of 5 mg carbon dioxide per hour has been reached. However, further increase in carbon dioxide concentration, i.e., more than 5 mg per hour will not increase the rate of photosynthesis. This is because the light now becomes the limiting factor. Under these circumstances, any further increase in the rate of photosynthesis can be brought about only if there is an increase in the light intensity. The above experiment shows that of all the factors, the photosynthetic rate depends upon the factor which is present in relatively minimum concentration. This factor is known as “limiting factor.” All other factors present in optimum or maximum concentration will not be able to increase the rate of photosynthesis until the amount of limiting factor is increased correspondingly.

Factors affecting photosynthesis - light intensity
There are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen production (number of bubbles or volume of oxygen gas given off in a set time)
the rate of carbon dioxide uptake
the rate of glucose production
Several factors can affect the rate of photosynthesis: light intensity
carbon dioxide concentration
temperature
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide. Increasing the light intensity increases the rate of photosynthesis, until some other factor - a limiting factor - becomes in short supply. previous

The rate of photosynthesis is directly proportional to the light intensity until another factor becomes limiting. At very high light intensities, photosynthesis is slowed, but these light intensities do not occur in nature. previous

 For example if we put soda lime (absorbs carbon dioxide)
with the plant and cover it with a plastic bag, the plant will be
lacking carbon dioxide and the rate of photosynthesis will
decrease. What are the factors affecting photosynthesis? The intensity of light, concentration of carbon dioxide and
temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs. What factors might affect a plant's rate of photosynthesis and therefore its ability to grow? Light intensity, ambient temperature, and carbon dioxide
concentration affect a plant's rate of photosynthesis and therefore
its ability to grow. What environmental factors does not affect the rate of photosynthesis? Everything except; Light intensity, Carbon Dioxide
concentration, Temperature
How does temperature affect the rate of photoysistes? The higher the temperature, the higher the rate of
photosynthesis.

Factors affecting photosynthesis - carbon dioxide and temperature
Carbon dioxide concentration
Carbon dioxide is one of the reactants in photosynthesis. If the concentration of carbon dioxide is increased, the rate of photosynthesis will therefore increase. At some point, another factor may become limiting and this is shown by the plateau (flattened section) of the graph. Temperature
The chemical reactions involved in photosynthesis are controlled by enzymes. As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate. As temperature increases the number of collisions increases, therefore the rate of photosynthesis increases. However, at high temperatures, enzymes are denatured and this will decrease the rate of photosynthesis.

 Second, for plants to remain alive, there generally must be a certain amount of water present at all times, which allows for photosynthesis to actually take place. In other words, if there was no water, the plant would die and photosynthesis wouldn't take place anyway. Water may be a limiting factor in some very specific climates and plant types, however. Lesson Summary
Let's take a couple moments to review how photosynthesis is impacted by environmental factors. Photosynthesis is the process by which plants create energy in the form of glucose from carbon dioxide, water, and sunlight. The chemical reaction also produces oxygen, which is released back into the atmosphere. Plants get carbon dioxide from the air, water through their roots, and energy from sunlight. We learned that light intensity, carbon dioxide concentration, and temperature are the three main factors that impact photosynthesis. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration. However, once light intensity and carbon dioxide concentration reach a certain level, photosynthesis rates level off and don't increase much further.

 The rate of photosynthesis goes on increasing with an increase in the concentration of carbon dioxide. Finally, the supply of carbon dioxide reaches 5mg per hour. At this point the two factors have a maximum effect on photosynthesis. Now light intensity is just enough to utilize 5 mg. Further increase in the supply of carbon dioxide will have no effect on the rate of photosynthesis. Thus light has now become the limiting factor. Rate of photosynthesis can increase only if light intensity is increased. Similar Articles: Factors affecting photosynthesis rate in a plant

Limiting factors of photosynthesis
A limiting factor is simply anything in short supply that prevents photosynthesis occurring at its maximum rate. If photosynthesis occurs more slowly in plant cells then a lower quantity of sugar will be produced and the quantity of chemical energy available for cell growth will be reduced. There are three important factors that can limit the rate of photosynthesis: Light intensity
Carbon dioxide concentration
Temperature
It is useful to be able to interpret a graph like the example below. This graph shows the effect of light intensity on the rate of photosynthesis at two different carbon dioxide concentrations. Light intensity is limiting the rate of photosynthesis at light intensities of 0 to 3.75 units. As light intensity is increased the rate of photosynthesis increases. At light intensities of 3.75 to 5.5, a carbon dioxide concentration of 0.03 per cent is insufficient and limits the rate of photosynthesis.

Factors affecting photosynthesis
There are several ways of measuring the rate of photosynthesis in the lab. These include: the rate of oxygen output
the rate of carbon dioxide uptake
the rate of carbohydrate production
These are not perfect methods as the plant will also be respiring, which will use up some oxygen and carbohydrate and increase carbon dioxide output. Several factors can affect the rate of photosynthesis: light intensity
carbon dioxide concentration
temperature
The amount of chlorophyll also affects the rate of photosynthesis: plants in lighting conditions unfavourable for photosynthesis synthesise more chlorophyll, to absorb the light required
the effects of some plant diseases affect the amount of chlorophyll, and therefore the ability of a plant to photosynthesise
Light intensity
Without enough light, a plant cannot photosynthesise very quickly - even if there is plenty of water and carbon dioxide and a suitable temperature. Increasing the light intensity increases the rate of photosynthesis, until some other factor – a limiting factor – becomes in short supply. previous

What is Photosynthesis? How It Occurs? - SCIENCE & BIOLOGY
 CO2 Concentration
As the concentration of carbon dioxide increases, so does the rate of photosynthesis. This occurs until it reaches a point where, no matter how much carbon dioxide is available, the rate will increase no more. There could be all the carbon dioxide in the world available to the plant but photosynthesis cannot go faster. This is because something else, such as light intensity, temperature or water availability, could be limiting the rate. Or it could be that all the enzymes are working at maximum speed and can't work any faster! Water Availability
The same goes with water availability. If there's a lack of water, that means one of the vital reactants for photosynthesis to occur is not available! This is quite rare because plants have particular adaptations (depending on their environment) to conserve water. Some have deep roots, some have thick cuticles, etc. Wind can increase the rate of water loss (transpiration) from the leaves, which has the potential to limit water availability.

Namely, the higher the light intensity, temperature, carbon dioxide and chlorophyll concentration, the faster the rate at which photosynthesis occurs. But there is an optimum rate. In the case of light intensity, photosynthesis rate is higher in red or blue light and very low in green light. Photosynthesis rate decreases with a decrease in water availability. Now that you understand the process of photosynthesis let’s look at its importance. Importance of Photosynthesis
Plants play an integral role in the continuity of life on the planet, all thanks to photosynthesis. They achieve that through the following: 1. Atmospheric Gases
In photosynthesis, plants take in carbon dioxide and release oxygen as a by-product. Without the process of photosynthesis, it would be difficult to replenish all the oxygen being used in processes such as combustion and respiration.

 After a point, however, the rate of photosynthesis remains constant as the light intensity increases. At this point, photosynthesis is limited by some other factors. Besides, the wavelength of light also affects the rate of photosynthesis. Different photosynthetic systems absorb light energy more effectively at different wavelengths. Carbon dioxide
An increase in the concentration of carbon dioxide increases the rate at which carbon is incorporated into carbohydrates in the light-independent reactions of photosynthesis. Thus, increasing the concentration of carbon dioxide in the atmosphere rapidly increases the rate of photosynthesis up to a point after which it is limited by some other factors. Temperature
The light-independent reactions of photosynthesis are affected by changes in temperature as they are catalyzed by enzymes, whereas the light-dependent reactions are not. The rate of the reactions increases as the enzymes reach their optimum temperature, after which the rate begins to decrease as the enzymes tend to denature. Process/ Steps of Photosynthesis
The overall process of photosynthesis can be objectively divided into four steps/ process: 1.

 This Law states that the rate of a physiological process will be limited by the factor which is in the shortest supply. In the same way, the rate of photosynthesis is also affected by a number of factors, which are namely; Light
As the intensity of light increases, the rate of light-dependent reactions of photosynthesis and in turn, the rate of photosynthesis increases. With increased light intensity, the number of photons falling on a leaf also increases. As a result, more chlorophyll molecules are ionized, and more ATPs and NADH are generated. After a point, however, the rate of photosynthesis remains constant as the light intensity increases. At this point, photosynthesis is limited by some other factors. Besides, the wavelength of light also affects the rate of photosynthesis. Different photosynthetic systems absorb light energy more effectively at different wavelengths. Carbon dioxide
An increase in the concentration of carbon dioxide increases the rate at which carbon is incorporated into carbohydrates in the light-independent reactions of photosynthesis.

 - Starch is stored in an organelle called Vacuole
What is meant by the 'rate of photosynthesis'? the process by which plants take carbon dioxide from the atmosphere, add water, and use the energy of sunlight to produce sugar. Main factors affecting the rate of photosynthesis
Light intensity: Without enough light, a plant cannot photosynthesize very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis. Carbon dioxide concentration: Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesize if there is insufficient carbon dioxide. Temperature: If it gets too cold, the rate of photosynthesis will decrease.

 If only I mg of the gas enters the leaf per hour, photosynthesis goes on at a certain rate. In this case the increase of intensity of light does not increase in the photosynthetic rate. The light is already present in excess. It is sufficient to utilize I mg of carbon dioxide per hour. He increased the supply of carbon dioxide to 2 mg per hour. The rate of photosynthesis increased at the same light intensity. This shows that the carbon dioxide concentration determine the rate of photosynthesis. Thus carbon dioxide is the limiting factor. ----------------------------

Blackman’s law of limiting factor:
 Leaves with Kranz anatomy are more efficient in photosynthesis. Blackman’s law of limiting factor: F. Blackman (1905) stated that “when a process is conditioned as to its rapidity by a number of separate factors, the rate of the process is limited by the pace of the slowest factor. ” This law is termed as Blackman’s law of limiting factor. It can be explained by the following example. Suppose a leaf is subjected to a light intensity, sufficient for the assimilation of 5 mg carbon dioxide per hour. Under these conditions, if a plant is supplied with only one 1 mg of carbon dioxide, the rate of photosynthesis would be limited by carbon dioxide (because concentration of carbon dioxide is less than what can be assimilated in the available intensity of light). Now if the carbon dioxide concentration is gradually increased, the rate of photosynthesis will also increase correspondingly until the assimilation rate of 5 mg carbon dioxide per hour has been reached. However, further increase in carbon dioxide concentration, i.e., more than 5 mg per hour will not increase the rate of photosynthesis. This is because the light now becomes the limiting factor.

About Sonia Madaan
 Chemical reactions occur with the help of protons from the water molecules and electrons from the chlorophyll molecules to produce Adenosine Triphosphate (ATP). ATP provides energy for cellular reactions and Nicotinamide Adenine Dinucleotide Diphosphate (NADP), which is integral in plant metabolism. Chemical Formula for the Process of Photosynthesis
This chemical formula summarizes the whole process of photosynthesis: READ: 25+ Stunning Facts About the Human Respiratory System
6CO2 +12H2O + Light → C6H12O6 + 6O2+ 6H2O
And there are six factors that influence the rate of photosynthesis: Temperature
Light intensity
Light wavelength
Carbon dioxide availability
Chlorophyll concentration
Water availability
Namely, the higher the light intensity, temperature, carbon dioxide and chlorophyll concentration, the faster the rate at which photosynthesis occurs. But there is an optimum rate. In the case of light intensity, photosynthesis rate is higher in red or blue light and very low in green light. Photosynthesis rate decreases with a decrease in water availability. Now that you understand the process of photosynthesis let’s look at its importance.

Influence of Light on Crop Growth
Quantity of light
Light quality
Light Duration or Photoperiod
 This point starts when light energy is sufficient for photosynthetic activity to produce more oxygen than is required by the plant for respiration. Likewise, the release of carbon dioxide through respiration by the plant must be less than the total carbon dioxide used by the plant for photosynthesis. In other words, the net photosynthesis (Eq. 1) is zero: Net Photosynthesis = Photosynthesis – Respiration (1)
Light saturation point. More light generally equates to higher levels of photosynthesis. However as the light intensity increases, the photosynthetic rate eventually reaches a maximum point. This point where the light intensity does not increase the photosynthesis rate is called the light saturation point. When this point is reached, the photosynthesis rate curve becomes flat (Figure 1). Figure 1.

 Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide. If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot. If you plot the rate of photosynthesis against the levels of these three limiting factors, you get graphs like the ones above. In practice, any one of these factors could limit the rate of photosynthesis.

The Effect of Oxygen Concentration on Photosynthesis in Higher Plants
https://doi.org/10.1111/j.1399-3054.1966.tb07046.x
Abstract
Citing Literature
 Oxygen might act as an electron acceptor at this site, causing reducing power to react back with molecular oxygen. However, this hypothesis does not account for equal inhibitions of the quantum yield and the light saturated rate of photosynthetic CO 2 uptake. Through the photosynthetic process plants take up carbon dioxide and evolve oxygen. The present high concentration of molecular oxygen in the atmosphere is generally considered to have arisen from the activity of photo‐synthetic organisms. The effect of oxygen concentration would seem, therefore, to he a problem of great interest, not only in the field of the biophysics and biochemistry of photosynthesis, but in ecology and other branches of biology as well. It was discovered by Warburg (1920) that high concentrations of oxygen inhibit the rate of photosynthetic oxygen evolution in the unicellular alga Chlorella. Since then, it has been confirmed by various authors that oxygen cconcentrations in the range 21–100 per cent have a marked inhibitory effect on photosynthesis, particularly at saturating light intensities. There is some evidence that under conditions when carbon dioxide concentration limits photosynthesis, the inhibition may become obvious even in 21 per cent oxygen. The inhibition has not been considered to operate at low light intensities. A review on the subject has been given by Turner and Brittain (1962).

 Plants also need nitrates to make proteins. These are absorbed from the soil as nitrate ions. Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis. Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide. If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.

 If it gets too hot the enzymes begin to lose their shape
(denature). This means they are unable to function properly and the
rate of photosynthesis decreases again. Also, at higher
temperatures the stomata close to prevent water loss. This also
stops gas exchange which slows photosynthesis even further. If it
is hot enough for water to boil this can be very harmful. 234

What Provides Electrons For the Light Reactions? Updated March 13, 2018
By Mike Charmaine
Photosynthesis is an important biochemical pathway involving the production of sugar (glucose) from light, water and carbon dioxide and releasing oxygen. It is a series of complex biochemical reactions and occurs in higher plants, algae, some bacteria and some photoautotrophs. Nearly every life depends on this process. The rate of photosynthesis is related to concentration of carbon dioxide, temperature and light intensity. It gets energy from absorbed photons and uses water as a reducing agent. Photosynthesis in the Past
With advent of life on Earth, the process of photosynthesis started. Since the concentration of oxygen was negligible, first photosynthesis took place using hydrogen sulfide and organic acid in sea water.
