WebJun 8, 2024 · Figure 4.4. 1: Surface Area to Volume Ratios: Notice that as a cell increases in size, its surface area-to-volume ratio decreases. When there is insufficient surface area to support a cell’s increasing volume, a cell will either divide or die. The cell on the left has a volume of 1 mm3 and a surface area of 6 mm2, with a surface area-to ... Some special cells can grow to very large sizes via an unusual endoreplication cell cycle in which the genome is replicated during S-phase but there is no subsequent mitosis or cell division (cytokinesis). These large endoreplicating cells have many copies of the genome, so are highly polyploid. Oocytes ...
