Ernest Z. Jun 20, Explanation: This is important if you are a cell that depends on diffusion through your cell wall to obtain oxygen, water, and food and get rid of carbon dioxide and waste materials.
As you get bigger, your outside is unable to keep up with needs of the inside. We can see this with agar cubes that have been soaked in NaOH solution. At this point, you must divide into smaller cells or die. Related questions How does surface area to volume ratio relate to photosynthesis?
How does surface area to volume ratio relate to cell division? The World of Cells. The Problem of Size. Why are cells so small? Cells are so small that you need a microscope to examine them. To answer this question we have to understand that, in order to survive, cells must constantly interact with their surrounding environment. As animals increase in size they require specialized organs that effectively increase the surface area available for exchange processes.
Key Terms surface area : The total area on the surface of an object. The cell on the left has a volume of 1 mm3 and a surface area of 6 mm2, with a surface area-to-volume ratio of 6 to 1, whereas the cell on the right has a volume of 8 mm3 and a surface area of 24 mm2, with a surface area-to-volume ratio of 3 to 1.
