Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

To stay alive, a cell needs materials to move in and out across its membrane. As a cell grows bigger, its volume increases ____ than its surface area. At a certain point, the cell’s volume would be ____ compared to the area available for materials to move in and out.

A	faster / too small
B	faster / too large
C	slower / too small
D	slower / too large

Explanation:

Detailed explanation-1: -Cells need air, water and food in order to function properly. Without these substances, cells cannot survive.

Detailed explanation-2: -As a cell grows, its volume increases more rapidly than its surface area.

Detailed explanation-3: -If a cell grows larger, then the volume increases much more rapidly than the surface area, causing the ratio of surface area to volume to decrease. The problem is that the cell would not be able to get enough oxygen and nutrients in and get the waste products out.

Detailed explanation-4: -As a cell grows, its volume increases more quickly than its surface area. If a cell was to get very large, the small surface area would not allow enough nutrients to enter the cell quickly enough for the cell’s needs.
