Step-by step Explanation:

The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and proteins. The main functions of the cell membrane include:

• Protecting the integrity of the interior cell.
• Providing support and maintaining the shape of the cell.
• Helps in regulating cell growth through the balance of endocytosis and exocytosis.
• The cell membrane also plays an important role in cell signalling and communication.
• It acts as a selectively permeable membrane by allowing the entry of only selected substances into the cell.
