Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The larger the surface area to volume ratio, the ____ efficient the cell is in transporting nutrients and waste in and out of the cell.
A
less
B
more
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -A larger surface area to volume ratio is more efficient than a smaller ratio. This is due to the amount of plasma membrane relative to the volume of the cell. The more plasma membrane available to transport materials in and out of the cell, the more efficient the cell will be in completing its specific functions.

Detailed explanation-2: -An increased surface area to volume ratio also means increased exposure to the environment. The finely-branched appendages of filter feeders such as krill provide a large surface area to sift the water for food.

Detailed explanation-3: -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.

Detailed explanation-4: -Answer and Explanation: A cell that has a “high” surface area to volume ratio will ensure efficient metabolism as it would have more surface area to obtain oxygen and nutrients and a low volume which means the oxygen and nutrients do not need to travel far to reach their destination.
