How Organisms Grow
A multicellular organism grows because cell division increases the number of cells in it.
As the organism develops and its cells divide, many of the cells become specialized, and most of them continue to divide.
Even when growth and development appear to stop, cell division is still occurring.
MITOSIS
Body Cells make more body cells by Mitosis.
Mitosis is a part of the cell cycle in which chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.
The Mitosis Cell Cycle is a division of the mother cell into two daughter cells, genetically identical to each other and to their parent cell.
MEIOSIS
Reproductive Cells are produced by Meiosis.
Meiosis is a specialized type of cell division which reduces the chromosome number by half. This process occurs in all sexually reproducing single-celled and multi-celled eukaryotes, including animals, plants, and fungi.
Errors in meiosis can cause miscarriages and the most frequent genetic cause of developmental disabilities.
