Answer 2

The structure which controls the entry and exit of materials through the cell is the plasma membrane.

What is a plasma membrane?

• Also called the semi-permeable membrane, the plasma membrane is the outer covering of the cell of all living organisms.
• It acts as a barrier between the internal environment of the cell and the external environment.
• The main function of the plasma membrane is to selectively allow the transport of water, minerals or other materials into and out of the cell.
• Thus, the plasma membrane is also called a selectively permeable membrane as it selectively permits some materials to enter or exit through the cell.
