Growth refers to the irreversible increase in size, mass, and volume of a plant due to cell division, cell enlargement, and an increase in the number of cells. It is a quantitative change.

Here is the difference between growth and development in plants:

• Growth refers to the irreversible increase in size, mass, and volume of a plant due to cell division, cell enlargement, and an increase in the number of cells. It is a quantitative change.
• Development encompasses all the changes that an organism undergoes throughout its life cycle, from germination to senescence. It includes growth, differentiation (cells specializing into different tissues and organs), and maturation, leading to the formation of complex structures and functions. It is a qualitative change.
