    Smaller size is a basic requirement of both Prokaryotic and Eukaryotic cell .<\/p>\n

    To understand this\u00a0 let us\u00a0\u00a0consider the area and volume of a typical cell.<\/p>\n

    Most cells have a spherical shape though not all.<\/p>\n

    The formula for calculating\u00a0 the surface area of a sphere is 4\u03c0r2<\/sup>, while the formula for its volume is 4\u03c0r3<\/sup>\/3.<\/p>\n

    Thus, as the radius of a cell increases, its surface area increases as the square of its radius,\u00a0but its volume increases as the cube of its radius .<\/p>\n

    Therefore one can understand that as a cell increases in size, its surface area-to-volume ratio decreases.<\/p>\n

    This same principle would apply if the cell had the shape of a cube .<\/p>\n

    If the cell grows too large, the plasma membrane will not have sufficient surface area to support the rate of diffusion required for the increased volume.<\/p>\n

    This would make the cell less efficient as it grows<\/p>\n

    The cell solves this problem by 2 ways<\/p>\n

      \n
    1. dividing<\/li>\n
    2. develops organelles that perform specific tasks.\u00a0 \u00a0These adaptations lead to the development of eukaryotic cells.<\/li>\n<\/ol>\n
