All algae, except prokaryotic cyanobacteria (formerly called blue-green algae), belong to the kingdom Protista. Algae all contain chlorophyll A, a primary pigment in cyanobacteria and plants, but differ in accessory pigments, which trap wavelengths of light to which chlorophyll A is not as sensitive.

These differences in pigments point to different roles and effects of algae on the ecosystem.
