Land plants (and plants in the ocean, called algae) have a lot of chlorophyll-a pigment because it is essential to photosynthesis, but they also have other pigments, called accessory pigments, that help them absorb light.
The plant's green pigment does not just provide color, it serves a vital function. Green plants efficiently use solar energy to make food. The food substance is in the form of sugars, starch, fat, protein and vitamins. The green pigment in plants, called chlorophyll, is what enables the plant to absorb the sun's rays or light energy, which is then converted to chemical energy.
