Final answer:
Each new cell formed by cell division has a smaller ratio of surface area to volume.
Step-by-step explanation:
Each new cell formed by cell division differs from the mature cell in that each new cell has a smaller ratio of surface area to volume. As a cell grows, its surface area-to-volume ratio decreases. This means that a larger cell will have a smaller ratio of surface area to volume compared to a smaller cell. A smaller ratio of surface area to volume makes it harder for the cell to get rid of its wastes and take in necessary substances, which limits the size of the cell.
