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

ANSWER:

(C) Volume

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.
