Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. In these complexes, chlorophyll serves two primary functions.hen sunlight returns in the spring and summer, the plants flourish in high concentrations. Chlorophyll (also chlorophyl) is a term used for several closely related green pigments found in cyanobacteria and the chloroplasts of algae and plants.
Chlorophyll is the pigment that gives plants and algae their green color. Plants use chlorophyll to trap light needed for photosynthesis (1) . The basic structure of chlorophyll is a porphyrin ring similar to that of heme in hemoglobin, although the central atom in chlorophyll is magnesium instead of iron.wo different types of chlorophyll (chlorophyll a and chlorophyll b) are found in plants (Figure 1). The small difference in one of the side chains allows each type of chlorophyll to absorb light at slightly different wavelengths.
