How does an increase in cell volume impact the diffusion of materials through the cytoplasm?

A. The size of the cell does not impact the movement of materials.
B. The larger the cell, the longer time it takes for materials to travel.
C. A larger cell does not require as many materials, so the need for diffusion decreases.
D. The larger the cell, the less time it takes for materials to travel.

Answer:

Option B, The larger the cell, the longer time it takes for materials to travel.

Explanation:

When the cell volume increases, the associated surface also increases. This means that the surface to area ratio will reduce. Reduction in surface to area ratio means that there will be less surface available for internal material (occupying a certain area with in the cell) and hence few things will only cross across the cell membrane. Therefore, longer time duration will be required to complete the diffusion across a cell membrane whose volume has increased.

Thus, option B is correct.
