Study Notes
Cell Division and its Types
- Cell division is the process in which a parent cell divides into two daughter cells.
- It is part of the cell cycle, where the cell grows and replicates its chromosomes before dividing.
- In eukaryotes, there are two types of cell division: mitosis and meiosis.
- Mitosis is a vegetative division that produces genetically identical daughter cells.
- Meiosis is a division that produces haploid gametes for sexual reproduction.
- Mitosis is a part of the cell cycle where replicated chromosomes are separated into two new nuclei.
- It ensures that genetically identical cells are produced with the same number of chromosomes.
- Mitosis is preceded by the S stage of interphase, where DNA replication occurs.
- Mitosis is often followed by telophase, which completes the cell division process.
- Meiosis, on the other hand, reduces the number of chromosomes in daughter cells.
- It reduces the number of chromosomes from two of each type to one of each type.
- Cell division is a fundamental process in cell biology that maintains genetic stability and enables reproduction.
