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 organelles called CHLOROPLASTS. More specifically, half of the photosynthesis chemistry stuff occurs in a liquid inside the chloropasts called STROMA, & the other half of photosynthesis occurs in stacks of membranes inside the chloroplast called GRANA. Turns out there are 2 types of chlorophyll, chlorophyll a & chlorophyll b.
