Expert Answer
Any function in the body of an organism takes place due to the activity of its cells.
(a) We are able to move our hand due to the contraction of muscle cells.
(b) Food gets digested in our body due to the enzymes secreted by the gut cells.
(c) In plants, root cells absorb water required for photosynthesis.
Thus, every function of the body is performed by a specific type of cell. Therefore, cell is said to be the functional unit of life.
