Cell Membrane Function Quizlet. The cell membrane is also known as plasma membrane or plasmalemma.this membrane separates the fluid outside the cell called extracellular fluid (ecf) and the fluid inside the cell called intracellular fluid (icf). Like a drawbridge intended to protect a castle and keep out enemies, the cell membrane only allows certain molecules to enter or exit.
Cell membrane is present in all organisms including plants. Biology is brought to you with support from the amgen foundation. Provides a selective barrier which allows only a certain molecules to enter and exit the cell.
It produces the membranes that surround the lysosomes.
The main functions of the cell membrane include: Glycosphingolipids, which are the most abundant in the animal cells, glycoglycerolipids, and glycophosphatidylinositol. Cell membrane is a protective covering that acts as a barrier between the inner and outer environment of a cell (in animals). The plant cell wall is mainly composed of cellulose and chitin.
