Photosynthesis (photo = light and synthesis = to make) is the process plants use to change carbon dioxide and water into sugar using sunlight. This sugar, glucose, is their food, and the process gives off oxygen. Photosynthesis is the conversion of light energy into chemical energy by living organisms.The raw materials are carbon dioxide and water. The energy source is sunlight, and the end-products include glucose and oxygen.It is arguably the most important biochemical pathway, since nearly all life depends on it.hotosynthesis is the conversion of light energy into chemical energy by living organisms.

Photosynthesis is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.arbon dioxide is converted into sugars in a process called carbon fixation. Carbon fixation is an endothermic redox reaction, so photosynthesis needs to supply both a source of energy to drive this process, and the electrons needed to convert carbon dioxide into a carbohydrate.
