Growth refers to the process through which the body increases in size and shape. It is a biological process. In other words, growth means increase in mass. From the time of conception, the process of growth starts in the mother’s womb. The fertilised egg continues to grow and after birth this process goes on till complete physical maturity is obtained. Growth is thus, a quantitative increase in size and shape. Physical growth refers to these changes in size and shape of different organs of the body, each of which normally proceeds at a different rate. Growth therefore, is a tangible biological process in which the organism gains in terms of size, volume, height, and weight.
