Answer 1

The correct option is D Only statement 3 is incorrect

Growth is defined as the irreversible increase in the size of an organ, its part, or an individual cell. It is one of the most important characteristics of living organisms. Growth is a result of various metabolic processes happening inside a body or a cell that occur at the expense of energy. In plants, the growth is indefinite i.e., plants keep on growing. An example of growth is the increase in the length of a tree.

Swelling of a piece of wood is not considered as growth in plants as it may increase the volume of wood but it is not accompanied by metabolic processes.
