Answer:
Lysosomes are organelles present inside the cell. They contain digestive hydrolytic enzymes that break down components of the cell such as cellular debris and foreign material. They also digest the cells in which they are present (autolysis) by their own enzymes. This results in cell death. Hence lysosomes are called as suicide bags of the cell.
Explanation:
✯ADDITIONAL INFORMATION
☆What is lysomes
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
✯major functions of lysomes
☆Intracellular Digestion
To digest food, the lysosome membrane fuses with the membrane of food vacuole and squirts the enzymes inside.
The digested food then diffuses through the vacuole membrane and enters the cell to be used for energy and growth.
☆Autolytic Action
Cell organelles that need to be get ridden are covered by vesicles or vacuoles by the process of autophagy to form autophagosome.
The autophagosome is then destroyed by the action of lysosomal enzymes.
✯Types of Lysosomes
☆Primary Lysosomes
- Small sac-like structures enclosing enzymes synthesized by the rough endoplasmic reticulum.
- Simply called as storage granules storing enzymes.
☆Secondary Lysosomes
- Formed by the fusion of primary lysosome with phagosomes.
- Contain engulfed material plus enzymes.
Materials are progressively digested
✯Structure of lysomes
☆Lysosomes are without any characteristic shape or structure i.e. they are pleomorphic
☆They are mostly globular or granular in appearance.
☆It is 0.2-0.5 μm in size and is surrounded by a single lipoprotein membrane unique in composition.
