What are two functions of the plasma membrane quizlet?
The Functions of the Plasma Membrane
- Physical isolation – separates inside of cell from the surrounding extracellular fluid.
- Regulation of exchange with the environment – controls the entry of ions and nutrients, elimination of wastes, and release of secretions.
What is the plasma membrane and what are its main functions?
The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its surrounding environment.
What are the 3 functions of the cell membrane quizlet?

What are the functions of plasma membrane class 9?
It separates the content of cell from their external environment. It allows the materials from surrounding to enter and exit the cell. It also allows the materials from cell to exit outside. It controls the entry and exit of materials in nd out of cell and hence it is called selectively permeable membrane.
What is the main function of the plasma membrane quizlet?
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer from tail to tail with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
What is the purpose of the plasma membrane Brainly?
Expert-verified answer – The plasma membrane helps the molecules to move in and out of the cell. – It allows protection of intracellular organelles from the outside environment. – The main functions in it are endocytosis and exocytosis.
