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.
Chlorophyll is also the substance that gives plants its green pigment because of its inability to absorb green light waves. Oregon State University says that 25 different chlorophyll pigments exist, the most common chlorophyll A and chlorophyll B. While two of the most common pigments, they have subtle differences.hlorophyll is also the substance that gives plants its green pigment because of its inability to absorb green light waves.
