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: -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 gets bigger, it has a difficult time keeping up with taking in the extra nutrients it needs and expelling more waste. In other words, as the cell gets bigger, it has less surface area compared to its size-the surface area to volume ratio of the cell decreases as it gets bigger.
