Read the following statements and choose the following option: 1. Growth is a reversible process 2. Growth does not involve metabolic processes 3. Growth can be defined as an irreversible permanent increase in size of an organ or its parts or even of an individual cell. 4. Growth does not occur at the expense of energy.

Step-by-step solution

Growth can be defined as an irreversible permanent increase in size of an organ or its parts or even of an individual cell. Generally, growth is accompanied by metabolic processes (both anabolic and catabolic), that occur at the expense of energy. Therefore, for example, expansion of a leaf is growth.
