Will mark bainliest. Why cells small?

Hint becose they small

They are small because they are small

Explanation:

They want to be small because they are small

Cells are so little, so they can maximize their ratio of surface area to volume. Smaller cells have a higher ratio which allow more molecules and ions 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.
