Chlorophyll is the substance that enables plants to create their own food through photosynthesis. A chlorophyll molecule consists of a porphyrin head (four pyrrole rings containing nitrogen arranged in a ring around a magnesium ion) and a long hydrocarbon tail. There are two types of photosynthesis; oxygenic photosynthesis and anoxygenic photosynthesis. They also produce amino acids and lipids required for the production of chloroplast membrane. It is essential for oxygenic PHOTOSYNTHESIS. Chlorophyll a is a specific form of chlorophyll used in oxygen ic photosynthesis.
