The function of cytoplasmic membrane:
•It is a physical barrier surrounds all cells and physically separates the cytoplasm. It shelters each cell part from the outer world, enables distinct processes to take place both within and outside the cell, and avoids mixing.
•Only particular molecules can move through them because they are selectively permeable; the membrane is easily accessible to water, oxygen, and carbon dioxide.
•Cell Signaling- it facilitates the communication and signaling between cells. The membrane also contains receptors that allow it to carry out certain works.
•Endocytosis and Exocytosis: Endocytosis is when a cell ingests larger contents and molecules that pass through pores freely. A cell can take in a lot of molecules by endocytosis. Exocytosis is when a cell releases these materials.
Each of these activities heavily relies on the cell membrane. The membrane's shape changes itself to allow other molecules to enter or leave the cell and form vacuoles. Small membrane bubbles can transport many molecules simultaneously to transport other materials to different places inside the cell.
