Question

Which of the following statements describes a benefit of most cells being small? A. Small cells move more quickly than larger cells. B. Small cells have a smaller surface-to-volume ratio than larger cells. C. Small cells have a greater surface-to-volume ratio than larger cells. D. Small cells move more slowly than larger cells.

Answer 1

C. Small cells have a greater surface-to-volume ratio than larger cells.

Step-by-step explanation:

Smaller cells have more surface area than volume to support interaction of the cell with surroundings and with other cells. Larger surface area supports diffusion of substances and exchange of energy with surroundings. Increase in cell size causes more increase in volume than that of surface area leading to reduced surface-to-volume ratio.
