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: -1: Surface Area to Volume Ratios: Notice that as a cell increases in size, its surface area-to-volume ratio decreases. When there is insufficient surface area to support a cell’s increasing volume, a cell will either divide or die.

Detailed explanation-3: -The surface area to volume ratio (SA:V) limits cell size because the bigger the cell gets, the less surface area it has for its size.

Detailed explanation-4: -Smaller cells have a much greater surface area to volume ratio allowing material to diffuse throughout the entire volume of the cell quickly and efficiently.

Detailed explanation-5: -A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell’s function is determined, in part, by its shape.
