The larger the surface area to volume ratio of a cell, the smaller its size (and vice versa).
A smaller cell has a higher surface area to volume ratio. A reason for this is volume is cubic (3D) and surface area is 2D so when surface area increases a little bit, the volume increases exponentially. And when the surface area shrinks a little bit, the volume decreases exponentially.
If you are talking about the relationship of cell size with cell volume..The smaller the cell, the healthier. This is because cell volume is expressed in units to the third power. Cell surface area is expressed in units to the second power. Therefore, cell volume grows exponentially quicker than cell surface area. Smaller cells are at an advantage, so they can transport enough substances through its membranes to support its volume.

They both increase with increasing cell radius (if we model a cell as a sphere). However, the rate of increase of the surface area is in general slower (dA/dr = 8πr) compared to the rate of increase of the volume (dV/dr = 4πr2). This would mean that with increasing cell size, the surface area to volume ratio is becoming smaller and smaller, giving a cell less surface area for the transport of nutrients for a given unit volume.
False. A smaller cell has a higher ratio of surface area to volume, making moving the amount of required nutrients simpler.
As the cell gets bigger, the surface to volume ratio gets smaller.
The surface area to volume ratio decreases - assuming the shape remains similar.
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger.Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membranefast enough to accommodate the increased cellular volume.When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function.That is why cells are so small.
