it is not affected by cell size

Explanation:
Detailed explanation-1: -As the radius of a cell increases, its surface area increases as the square of its radius, but its volume increases as the cube of its radius (much more rapidly). Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
Detailed explanation-2: -1 Answer. Cell growth causes the surface area to volume ratio to decrease. This is because, as a cell grows, the volume of the cell (its internal contents) increases faster than its surface area (its cell membrane).
Detailed explanation-3: -Answer: 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.
