The important point is that the surface area<span> to the </span>volume ratio<span> gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cell<span> grows beyond a certain </span>limit<span>, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular </span>volume<span>.</span>
