Question

Why are lysosomes known as suicidal bags?

Answer 1

Lysosomes are membrane-bound vesicular structures that contain powerful digestive enzymes.

These enzymes are capable of breaking down any foreign food particle or microbes entering the cell.
Sometimes, lysosomes can cause self-destruction of a cell by releasing these digestive enzymes within the cells. Hence, they are also known as ‘suicidal bags’.

Or,

During break down of the cell structure the damaged lysosomes may burst and the enzymes eat up their own cells.
Therefore lysosomes are also known as suicidal bag of the cell.

Lysosomes are also called digestive bags because they destroy any foreign material which enter the cell such as bacteria and virus
they serve as intracellular digestive system.
