Detailed explanation-1: -When there is insufficient surface area to support a cell’s increasing volume, a cell will either divide or die.
Detailed explanation-2: -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-3: -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.
Detailed explanation-4: -If a cell became too large, an “information crisis” would occur. The cell has more trouble moving enough nutrients and wastes across the cell membrane. The rate at which food, oxygen, and water enter the cell, as well as wast products leave the cell, depends on the surface area of the cell and the cell’s volume.
Detailed explanation-5: -If a cell got too large, it would be more difficult to get sufficient amounts of oxygen and nutrients in and waste products out.
