Lysosomes

Question 1 Explain the structure of lysosomes?

Question 2 What are the functions of lysosomes?

Question 3 Why lysosomes are called digestive bags?

Lysosomes
They are simple tiny spherical sac like structures evenly distributed in the cytoplasm.
Each lysosome is a small vesicle surrounded by a single membrane and contains enzymes.These enzymes are capable of distributing or breaking down all organic material.They are made of RER.

Functions
1)They are called digestive bags.They destroy any foreign material which enter the cell such as bacteria and virus.
2)They remove worn out and poorly working cellular organelles by digesting them to make way for their new replacements.
3)They are called suicide bags of cell.During break down of cell structure,when cell gets damaged,lysosomes may burst and enzymes eat up their own cells.
