Chlorophyll is the green pigment found in algae and plants. Chlorophyll, a biomolecule, constitutes the main site of photosynthesis in plants. Chlorophyll appears green, as it absorbs red and blue colors of light and reflects green color. There are also synthetic, inorganic green pigments.
Chlorophyll is synthesized in the presence of sunlight and its production declines in decreased sunlight. Through photosynthesis, chlorophyll is part of an energy conversion process that leads to green pigment. Types of chlorophyll include chlorophyll - a, chlorophyll - b, chlorophyll - c1, chlorophyll - c2, chlorophyll - d and divinyl chlorophyll – a. All of their basic structures are similar, with slight differences in their chemical structures. Slight structural differences account for their different green shades.
