Answer:
SA/V
Step-by-step explanation:
Surface area to volume ratio literally means the ratio of surface to the volume of the cell.
Simple unicellular organisms tend to have larger surface area to volume ratio due to their lesser complexity, as compared to complex multicellular organisms with lesser surface area to volume ratio, due to increased complexity.
Organisms with large surface area to volume ratio have higher tendencies to grow and divide, and as their surface areas to volume ratio decrease, the ability to divide/reduces, until it finally stops.
Therefore, large SA/V favours growth and cell division while small SA/V impedes growth and cell division.
