Question

Why are cells so small? In your answer, use the terms volume, distance, diffusion, surface area, plasma membrane.

Answer 1

Cells are so little, so they can maximize their ratio of surface area to volume.

Step-by-step explanation:

Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.
