Diffusion and Cell Size Introduction
... Why are cells so small? Most cells grow, but upon reaching a certain size, a cell will divide becoming two smaller cells. This is how multi-cellular organisms, like us, grow. But why do cells stop growing when they reach a certain size? Why does a cell divide and multiply rather than simply continue ...
