The cell is the smallest unit that makes up all living organisms and body tissues.
All living things are made up of cells which are the structural, functional, and biological components.
There are trillions of cells in living organisms.
A cell has the capability of self-replication.
As a result, they're known as life's building blocks.
Requirement of Cell division:
Cell division is required for the renewal of damaged cells, the synthesis of new cells from older ones, the provision of more cells for growth and development, the repair and management of cell damage, and the survival and growth of living things.
To reestablish the nucleo-cytoplasmic ratio, cells must divide.
