<p>As a cell becomes larger, its volume increases more than its surface area, leading to inadequate surface area for materials to enter or leave the cell quickly enough to meet its needs. This sets upper limits on the size of cells, as larger cells do not have enough surface area to meet their metabolic requirements.</p> Signup and view all the answers

<p>The surface area to volume ratio in cells determines the amount of surface area per unit of volume, which sets limits on the size of cells. A higher surface area to volume ratio allows for more efficient exchange of nutrients and wastes, while a smaller ratio is not beneficial for the cell.</p> Signup and view all the answers

<p>A higher surface area to volume ratio allows for more efficient exchange of nutrients and wastes, enabling the cell to meet its metabolic requirements. Conversely, a smaller ratio leads to inadequate surface area for metabolic needs.</p> Signup and view all the answers

<p>Most cells are microscopic in size because as cells become larger, their volume increases more than their surface area, resulting in inadequate surface area to meet their metabolic needs.</p> Signup and view all the answers
