Explanation:
The unifying theory in biology notes that cells are the fundamental units in biological life. Cells with common origins are clustered together in the body to form tissues; they usually share physical characteristics and are organized into regular structures- these are the smallest units capable of survival. All living organisms, respire, grow, reproduce, etc. these processes are carried out by cells, and are therefore essential to their existence.
