The plasma membrane helps to maintain homeostassi within the cell by allowing substances to move in and out of the cell the plasma membrane is used to maintain homeostasis within the cell by allowing substances to move in and out of the cell
Projections that allow the cell to move or to move substances along the surface of the cell are called cilia and flagella. Flagella is a single long hair that allows the cell to swim. Cilia are several projections used for movement across the cell surface.
Phagocytosis is the process of moving solids across a cell membrane into a cell.
Osmosis is the movement of fluid and substances in and out of a cell through the cell well. Transference is also a way for things to move in and out of a cell.
