Detailed explanation-1: -Cell size is limited by a cell’s surface area to volume ratio. A smaller cell is more effective and transporting materials, including waste products, than a larger cell. Cells come in many different shapes. A cell’s function is determined, in part, by its shape.
Detailed explanation-2: -A larger surface area to volume ratio is more efficient than a smaller ratio. This is due to the amount of plasma membrane relative to the volume of the cell. The more plasma membrane available to transport materials in and out of the cell, the more efficient the cell will be in completing its specific functions.
Detailed explanation-3: -Cells are so little so that they can maximize their ratio of area to volume. Smaller cells have a better ratio which allows more molecules and ions to be manipulated across the cell membrane per unit of cytoplasmic volume.
