Question

growth is equivalent to increase in cell number. justify

Answer 1

The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. ... An increase in cytoplasmic mass does not always occur during cell-division cycles, however.

the cells engaged in growth may be widely distributed throughout the body of the organism, as in the human embryo. In the latter case, the rates of cell division and of the increase in cell size differ in different parts. That the pattern of growth is predetermined and regular in plants and animals can be seen in the forms of adults. In some organisms, however, notably the slime molds, no regular pattern of growth occurs, and a formless cytoplasmic mass is the result.
