o-na [289]

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?​
tangare [24]

Answer:

Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.
