|
|
a small cell weighs very little and is more able than a large cell to conserve energy.
|
|
|
a small cell takes up less room than a large cell.
|
|
|
a small cell has a small volume relative to surface area, increasing its efficiency of obtaining nutrients.
|
|
|
a small cell has a small surface area relative to volume, increasing its access to nutrients.

Detailed explanation-1: -Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.
Detailed explanation-2: -Small cells extend coverage and add capacity to public mobile networks, especially in high-density areas like cities. They are an excellent supplement where a macro cell is struggling to keep up with growing demands, such as in dense residential, metropolitan, or commercial areas.
Detailed explanation-3: -A cell with a smaller surface area to volume ratio has less plasma membrane and more volume. The larger the size of the cell, the larger the volume, and therefore the more time it takes for substances to move through the cell.
Detailed explanation-4: -A small cell (left), has a larger surface-area to volume ratio than a bigger cell (center). The greater the surface-area to volume ratio of a cell, the easier it is for the cell to get rid of wastes and take in essential materials such as oxygen and nutrients.
