what is the role of cell division in the development in multicellular organisms
One of the most important characteristics is that both you and they are made of trillions of cells. But, like most organisms, you and they started out as single cells. In multicellular organisms, cell division is essential for three major functions: growth, development, and repair. Through cell division, a single cell becomes two cells. Those two cells divide into four, and the four cells divide into eight, and so on.
