As a cell increases in size, its surface area to volume ratio decreases, making nutrient absorption less efficient.

Larger cells always absorb nutrients more efficiently because they have more membrane.

The shape of a cell has no impact on its ability to absorb nutrients.

Small cells have a smaller surface area to volume ratio, making them more efficient at waste removal.
