Cell: The Unit of Life

Cell - the structural and functional unit of life - called so because it gives structure to the organism and performs the functions of the organism.

Anything that consists of a cell at least (unicellular organisms) are capable of:

• independent existence and
• perfoming the essential functions of life

And anything less does not ensure these. So, cell is the structural and functional unit of all living organisms.

The difference between the living beings and non-living is the cell.

All organisms are made up of cells and based on the number of cells there are:

• Unicellular Organisms
• Multicellular Organisms
