• A. Auxetic growth
• B. Multiplicative growth
• C. Accretionary growth
• D. Differential growth

Answer 1

The correct option is A Auxetic growth

A. Auxetic growth – Growth takes place only by an increase in the volume of cells.

B. Multiplicative growth – Growth takes place only by an increase in the number of cells.

C. Accretionary growth - It involves a cell secretion to increase the volume of the extracellular spaces. Many adult tissues will only divide when induced by injury or other stimuli. It occurs in cartilage and bone.

D. Differential growth – Growth involves the formation of different types of cells.

So, the correct option is ‘Auxetic growth’.
