WebDiatoms are phytoplankton that floats on the water surface. They are the primary photosynthetic producers in marine food chains and store their food as lipids and polysaccharide leucosine. Since lipids have a lesser density than that of seawater, diatoms store oil or lipids in their vacuoles to maintain the buoyancy and thereby to float on water.
