As a cell becomes smaller its surface-area-to-volume ratio?
The surface area to volume ratio decreases - assuming the shape remains similar.
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
How does a surface area of a solid vary with its volume?
Provided the shape remains similar, the surface varies as the 2/3 power of the volume. Or, to put it another way, the cube root of the volume varies directly as the square root of the surface area. Or, the square of the volume is in direct proportion to the cube of the area.
How does a small surface area per unit volume help cacti live in areas that are dry for long periods of time?
Any living thing that has a low surface area per unit of volume will lose less moisture to evaporation than a living thing with a high surface area to volume ratio.
Is it better to have a big surface area with a small volume or small surface area with a big volume?
It doesnt matter at all, because the volume immobilizes the size of the needed surface to cover the whole thing in order to view it as a separated 'space'. The shape of the whole thing has no influence at all. The bigger the volume, the larger the surface & vice versa.
