Chlorophyll determines the intensity of photosynthesis that produces glucose. Glucose is stored in plant cells in the form of starch. Chlorophyll and and starch are separated in space. Chlorophyll is a component of special membrane structures (thylakoids) in chloroplasts. Starch is stored in a chloroplast stroma. It can be easily determined using iodine that binds with starch granules making them purple while chlorophyll is green.
How can u compare the distribution of starch and the distribution of chlorophyll?
