Each mature Volvox colony is composed of up to thousands of cells from two differentiated cell types: numerous flagellate somatic cells and a smaller number of germ cells lacking in soma that are embedded in the surface of a hollow sphere or coenobium containing an extracellular matrix made of glycoproteins. All algal cells have a definitive cell wall that is thin in some species, but in others, like diatoms, the cell wall is impregnated with silica, which makes it rigid and hard. Unicellular algae occur most frequently in water, especially in plankton. These pigments let them capture light and live in deep water. Cyanobacteria is responsible for changing the environment on Earth, allowing it to support living organisms, plants, and algae that evolved throughout history. Based on Spore Formation . Moreover, protists that exhibit similar morphological features may have evolved analogous structures because of similar selective pressures—rather than because of recent common ancestry.
