Biology Cell Division Meiosis Mitosis
Cell Division#
. It is essential for growth, repair, and reproduction in all living organisms. There are two main types of cell division: mitosis and meiosis.
Mitosis#
Mitosis is the process by which a . It occurs in somatic cells (all cells other than sex cells) and is responsible for growth, repair, and asexual reproduction.
The process of mitosis can be divided into four stages:
- Prophase: During prophase, the chromosomes become visible and the nuclear membrane begins to break down.
- Metaphase: During metaphase, the chromosomes line up in the center of the cell.
- Anaphase: During anaphase, the chromosomes are separated and pulled to opposite ends of the cell.
- Telophase: During telophase, two new nuclear membranes form around the chromosomes and the cell membrane pinches in the middle, dividing the cell into two daughter cells.
Meiosis#
Meiosis is the process by which a , each with half the number of chromosomes as the parent cell. It occurs in gametes (sex cells) and is responsible for sexual reproduction.
