Thank you for the opportunity to help you with your question!
The structure of the plasma membrane consists of the phospholipid bilayer, which gives it a fluid structure, rigid, allowing the materials ease to pass through. Next, there are also integral proteins which can be thought of as 'tunnels', allowing the materials to come in and out. Then, there are peripheral proteins which also aid in getting the materials inside an out
Cell membrane plays an important role in maintaining the homeostasis by controlling the substances that penetrate the cell, either entering the cell, or leaving the cell.
