Functions of Cell Membrane

1. The Cell Membrane is selectively permeable i.e. it allows only selected substances to pass through.
2. It protects the cells from shock and injuries.
3. The fluid nature of the membrane allows the interaction of molecules within the membrane. It is also important for secretion, cell growth, and division etc.
4. It allows transport of molecules across the membrane. This transport can be of two types:

Active transport – This transport occurs against the concentration gradient and therefore, requires energy. It also needs carrier proteins and is a highly selective process.

Passive transport – This transport occurs along the concentration gradient and therefore, does not require energy. Thus, it does not need carrier proteins and is not selective.
