Among unicellular eukaryotes, cell sizes differ greatly. Also paramecium lack chlorophyll which seems to preclude the existence of a cell wall. The body is typically covered by a complex living, stiff but flexible pellicle, best studied in Paramecium. Most ciliates also have one or more prominent contractile vacuoles, which collect water and expel it from the cell to maintain osmotic pressure, or in some function to maintain ionic balance.
