Why are cells essential for our life?

The cell is the smallest biological, structural, and functional unit of all living beings. All the living organisms are made of different types of cells. Cells are the basic units or building blocks of life.

A cell performs different vital functions like respiration, digestion, reproduction, and many more to keep itself alive. The human body is made of trillions of cells.

The existing living cells are able to split themselves into two parts, thereby forming new cells. The cells' genetic material is duplicated before it undergoes splitting.

Hence, new cells are formed using existing cells.
