The total number of new cases of Crohnâs disease diagnosed each year (incidence) was 10.7 per 100,000 people, or approximately 33,000 new cases per year. The total number of new cases of ulcerative colitis diagnosed each year was 12.2 per 100,000 people, or approxi-mately 38,000 new cases per year (Figure 3).
The most important part of photosynthesis occurs in the chloroplasts. These small photosynthesis factories buried within the leaves house chlorophyll, a green pigment secreted in the chloroplast membranes. Chlorophyll absorbs a wide range of the spectrum of sunlight, giving the plant as much energy as it can for its reactions.
Photosynthesis occurs when the Cholorophyll which is a green colour pigment present in the choloroplast of green plants absorbs light energy and uses this energy to carr â¦ y out the reaction of carbon di oxide(from air) with water(from soil) to produce glucose and oxygen as a bi-product which is released in the air. gulucose is used as a plant food.
