Explanation;
-The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
-The surface area to volume ratio of an object is the relationship between two measurements. It is the ratio of Surface area to volume. It shows the comparison between the size of the outside of an object and the amount inside. Small or thin objects have a large surface area compared to the volume.

<span>Growth harmones are released from pitutary gland in to the blood stream. This harmone promotes growth in children till they grow upto 15-18 years. Then this harmone stops. The excess secretion of this harmone leads to over height that is Gigantism. the dificiency of growth harmones are leads to shortness i.e. dwarfinism. The growth harmones secretes equally in both boys and girls. It secretes in hypothalamus of the brain</span>
