Question

Living cells generally can have any large dimension, EXCEPT __________________, because materials must move into and out of the cell rapidly by diffusion.

A) width 
B) length
C) volume 
D) surface area

Answer 1

(C) Volume

Step-by-step explanation:

When the volume of living cells increases, the surface area of the cell decreases. They are inversely proportional to each other. For example, in small intestine, there is a relatively high rate of diffusion because it has a increased surface area to volume ratio.

Answer 2

Living cell generally can have any large dimension except volume.This is because increase in volume will led to more ratio of volume than surface area which means there will be more units of volume for each unit surface area which make substance to take longer to diffuse into the cell.
