Question

(ii) Cells have a large surface area / volume ratio
for greater diffusion of substances in and out
of the cell.
can someone plz explain what this means
thanks​

Answer 1

Answer:

The surface area--to-volume ratio makes the small cells more efficient, not the rate of diffusion. Smaller cells, with a larger surface area--to--volume ratio, are more efficient for diffusing materials in and out because, as a cell grows, the volume grows faster than the surface area.
