Lysosomes are involved in the following functions;

1. Removal of dead cells:

Lysosomes aid in the removal of dead cells in tissues such as white blood cells with engulfed bacterium in blood, cells in the outer layer of skin and mucous membrane linings of the body.

 Lysosomes contain a sufficient complement of enzymes to digest most types of biological or organic materials and the digestive process occurs quite rapidly in dead cells. This process of tissue degeneration is due to this lysosomal activity.

2. Help in protein synthesis:

Lysosomes break down macromolecules into their respective constituent parts, which are then recycled. These membrane-bound organelles contain enzymes known as hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars

3. Role in metamorphosis:

This is mostly seen clearly in the metamorphosis of a frog. Disappearance of tail from tadpole larva of frog is due to lysosomal activities

4. Help in fertilization:

During fertilization the sperm’s head secrete some lysosomal enzymes which aid in the penetration of sperm into vitelline layer of ovum..

5. Role in osteogenesis:

Formation of bone cells depends upon lysosomal activities. Ageing of cells and parthenogenetic development are related with the lysosome activities.
