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 takes place in the cell's chloroplast in two stages: the light stage and the dark stage. Each stage occurs in a different part of the chloroplast. In the light stage of photosynthesis, the chloroplast absorbs the light of the sun. This sets off a series of chemical reactions, beginning by converting the sunlight to chemical energy. According to About.com, three types of energy are produced: ATP, NADPH and oxygen, all of which are used in the dark stage of photosynthesis.
