Cell Membrane is present in all organisms including plants

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:

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