Question

The smallest living unit is
A) a cell.
B) an organ.
C) a human being.
D) a molecule.

Accepted Answer

A cell is the smallest living unit as it is the basic structural and functional unit of all living organisms. Molecules are smaller than cells but they are not living units as they do not possess all the characteristics of living organisms. Organs are made up of multiple types of cells and tissues and cannot be considered the smallest living unit. Similarly, a human being is made up of multiple organs and cannot be considered the smallest living unit.
