- Green pigment present in the majority of
- plants, which is responsible for the
- absorption of light energy during the light
- reaction of photosynthesis. It absorbs the
- red and blue-violet parts of sunlight but
- reflects the green, thus giving the
- characteristic colour to most plants.
- Chlorophyll is found within chloroplasts,
- present in large numbers in the leaves.
- Cyanobacteria and other photosynthetic
- bacteria also have chlorophyll, though of a
- slightly different type. Chlorophyll is
- similar in structure to haemoglobin, but with
- magnesium instead of iron as the reactive
- part of the molecule.
