Question

How do you say that a cell also has a life span and death like an organism? Give one example.

Answer 1

Cells are structural and functional living entities. It consists of organelles that undergo respiration and eliminate waste. They have a life span that is definite. As living entities are not immortal and die at a certain point in time, cells also die. Death of cells in human body takes place every second.
Because of the presence of cell organelles namely, lysosomes(suicidal bags) we can deduce that cells have a life span and death as seen in a living entity. The cell age, deteriorate, get damaged and die through a process known as apoptosis. Lysosomes are responsible for the death of a cell.
