Final answer:
As a cell increases in size, its surface area-to-volume ratio decreases, which affects important cellular processes.
Step-by-step explanation:
As a cell increases in size, its surface area-to-volume ratio decreases. This can be explained by the fact that as the cell grows, its volume increases much more rapidly than its surface area. Surface area is important for processes like diffusion, which is crucial for the cell to obtain nutrients and get rid of waste. If a cell becomes too large and has a low surface area-to-volume ratio, it may not have enough surface area to support all the necessary cellular activities.
