Question

Give two main reasons that cells generally remain small in size.

Answer 1

Explanation :

The two main reasons that cells generally remain small in size are :-

• Different regions of cell can communicate with each other rapidly of the cell to function effectively.
• Cells have large surface area / volume ratio is greatest diffusion of substance in and out of the cell.

Answer 2

Explanation:

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