Define growth and explain it.

(N/A) Definition: Growth is defined as an irreversible,permanent increase in the size of an organ,its parts,or an individual cell.
Explanation: Growth is considered one of the most fundamental and conspicuous characteristics of a living organism.
Growth is accompanied by metabolic processes (both anabolic and catabolic) that occur at the expense of energy.
Example: The expansion of a leaf is considered growth,whereas the swelling of a piece of wood when placed in water is not considered growth because it is reversible and not metabolic.
