Explain why cells don't just continue to grow larger as organisms grow larger. Why do cells divide?

    Cell divide because of the surface area to volume ratio.

    Cells are so small, so that they can increase their ratio of surface area to volume.

    Surface area is defined as area covered by outside (or surface) membrane which is called as cell membrane.

    Volume of cell is defined as space used by inner cellular contents.

    Therefore, cells are so small, so that cell membrane can supply the inside organelles or contents with their needs in order to survive.

    If the ratio of surface area to size is too small, then mitosis or other processes will not work and cell cannot survive. Therefore, surface area should be larger than the volume of cells for these processes to occur.

    Cell divide because of the surface area to volume ratio. If the surface area to volume ratio is too small, mitosis and other processes that we in the body will not work. The surface area needs to be larger than the volume of cells for these processes to strive.

    Cells will not grow when the organism grows but it multiplies by the mitosis process.

    Therefore, growth of an an organism states more and more cells which is possible by cell division.

    When cells grow during mitosis chromosomes are duplicated in interphase stage proteins and organelles are produced that increases the volume of cell but surface area remains the same. Then during cell division, the volume of cytoplasm in the two daughter cells are divided that increases the surface area to volume ratio of the cells.
