cell membranea double-layered covering thatsupporls the cell and allowssome substances to move inand out of the cell. The cellmembrane is in contact withthe surroundings, includingother cells, so can be involvedin communication.

ciliatiny hair-like projections onthe cell membrane. They caneither detect movement ormove to create a current inthe surrounding liquid.
