The surface area/volume ratio is an important factor for one celled organisms. as a cell's volume grows, its surface area/volume ratio decreases, making it harder and harder to acquire enough nutrients via diffusion. because of this, cells stop growing after reaching a certain size. after reaching this state, a one celled organism is likely to a) enter into a spore state. b) continue to grow until it is so big it bursts. c) use mitosis to divide and create daughter cells. d) stop eating so that it shrinks and its surface area/volume ratio grows.
