Cellular And Molecular Basis Of Animal Growth And Development

Growth is a natural process in any living being including animals. Growth in animals happens when the cells inside the organism start to divide and multiply. The speediest cell division occurs in an unborn newborn mammal. The animal’s cells continue to divide after birth, causing it to grow larger.

growing organism’s growth in size and changes in shape are dependent on the individual’s increased quantity and amount of cells. Growth is a size expansion. A living entity grows as the size and quantity of its cells increase. The animal’s cells continue to divide after birth, causing it to grow larger. An animal’s cell division slows down as it ages.

Cell division mostly takes place in mature animals to replace aged and dead cells. After birth, several animal organ systems experience minimal cell division or development.
