Question

Cells have a __(large / small) surface area for greater diffusion of substances in and out of cell.

Answer 1

Cells have a large surface area for greater diffusion of substances in and out of the cell. The larger surface area relative to the volume of the cell ensures greater diffusion of nutrients into the cell, metabolic wastes from the interior to the outside of the cell, respiratory gases i.e. oxygen into the cell and carbon dioxide out of the cell.
