The Fundamental Unit of Life — Science STD 9 — Question

4. It has a larger surface area to volume ratio compared to larger cells and therefore, provides a more efficient exchange of nutrients and waste products.

Explanation:
Cells and their membranes are small so that they can maximize their surface area to volume ratio. Cells have a higher ratio that allows more molecules and ions i.e.nutrients and waste products across the cell membrane per unit of cytoplasmic volume. The greater surface area helps to increase the efficiency by allowing active transportation and exchange across the membrane.
