Phytoplankton, also known as single-celled plants, grow in water-bodies and are similar to terrestrial plants in many ways. Since they require sunlight for photosynthesis, these plants usually grow on the surface of water, in the photic zone, where sunlight can penetrate. These plants also require other nutrients such as nitrate, magnesium, zinc, etc to grow.
Phytoplankton drifting about below the surface of the water still carry out photosynthesis. This process can occur as long as enough light is available for the chlorophyll and other pigments to absorb. In the ocean, light can reach as far as 200m below the surface 25.hlorophyll is not the only photosynthetic pigment found in algae and phytoplankton. There are also carotenoids,and phycobilins (biliproteins). These accessory pigments are responsible for other organism colors, such as yellow, red, blue and brown.
