PROCESS OF GROWTH OF CHILD INSIDE OF WOMEN"S BODY
Life for the human being begins with the meeting of two cells namely the egg (from the mother) and the sperm (from the father) inside the women"s body. The egg and the sperm unite to form a single cell. This tiny,single cell migrates to the uterus and it is there that it eventually grows to from the foetus . This single cell first divides into two cells, then four, eight and many such cells. As a result,there is a tremendous increase in cell numbers. Cell size also increase. But all cell are not the same. Gradually cells becomes specialized structure and function. Cells of similar types align themselves to the tissue. Such tissues then from the cells organs continuous. Growth refers to the physical increases in the the sizeof the body and its organs. Development ,on the other hand, denotes a qualitative change.
