The cell is the functional unit of living organisms because

  1. multicellular organisms consist of cells
  2. all cells in a multicellular organism function as a single cell
  3. the function of a multicellular organism is the sum total of its constituent cells ✓
  4. the function of a single cell is superior to that of the multicellular organism
Explanation

A cell carries out all the basic life processes: feeding, respiring, growing and reproducing. A multicellular organism is made of many cells working together.

So the function of a multicellular organism is the sum total of its constituent cells. That is why the cell is called the functional unit of life.
