Increase in size of a body part or the organism as a whole is known as what?

• A. Growth
• B. Hypertrophy
• C. Excretion
• D. Digestion

Answer: (A)

Growth is the process by which a body part or the whole organism becomes larger. It includes increases from more cells (hyperplasia) and from bigger cells (hypertrophy), driven by development and adaptation. Hypertrophy is specifically enlargement of existing cells, which contributes to growth but isn’t the general term for size increase. Excretion and digestion are unrelated to size changes, as they deal with waste removal and nutrient processing, respectively. So the overall increase in size is described as growth.
