AP BIOLOGY

Detailed explanation-1: -As a cell grows, its volume increases much more rapidly than its surface area.

Detailed explanation-2: -As cells grow larger, their volume increases faster than their surface area. This leads to a decrease in the efficiency of the cell at exchanging materials across the cell membrane. To be able to efficiently exchange materials, cells must divide by mitosis and cytokinesis when they become too large.

Detailed explanation-3: -For example, cell volume can increase either from the normal growth or from the accumulation of water. Apoptotic shrinkage can be caused by cell fragmentation or by water loss. Only by complementing cell volume measurements with MC, these cases can be easily differentiated.
