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: -Seeing that the surface area to volume ratio of cells generally decreases as cells get larger, making the exchange of resources, waster and heat more and more difficult.
Detailed explanation-3: -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-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.
