1.3D cell size: surface area to volume ratios
Term | Definition |
---|---|
surface area | the area of a cell that is exposed to its external environment; if a cell is shaped like a sphere or a ball, the surface area can be calculated by this following equation: surface area = 4πr2 where π= 3.14 (approx.) |
volume | the volume of a cubical cell can be calculated by the following equation: side length x height x width |
surface area to volume ratio | a greater surface-area-to-volume ratio makes a cell more efficient; the smallest cells have the greatest surface-area-to-volume ratios and are the most efficient at transporting molecules across the cell membranes |
