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 in all green plants and a few other, simple... Photosynthesis occurs when green plants harness the energy in sunlight and convert it to chemical energy in the form of sugars. Photosynthesis occurs in all green plants and a few other, simple... Photosynthesis occurs when green plants harness the energy in sunlight and convert it to chemical energy in the form of sugars. Photosynthesis occurs in all green plants and a few other, simple organisms, such as algae and some bacteria. Photosynthetic organisms typically feature small structures called chloroplasts in their cells. Chloroplasts require several ingredients to complete the act of photosynthesis.
