Question
Why do most cells remain microscopically small?
- AA higher surface-area-to-volume ratio supports exchangeCorrect
- BLarge cells cannot contain DNA
- CSmall cells do not need energy
- DOnly tiny cells can divide
Correct answer
A higher surface-area-to-volume ratio supports exchange
Explanation
Smaller cells exchange materials more efficiently because their surface area remains high relative to their volume.
