Question
Mention the role of nucleus, centrosome and mitochondria in cell division.
Answer
- Nucleus:
- Holds the cell’s genetic material (DNA) in the form of chromosomes.
- Regulates cell division by coordinating DNA replication and distributing chromosomes to daughter cells during mitosis and meiosis.
- Centrosome:
- Organizes microtubules, forming the mitotic spindle necessary for cell division.
- Helps separate duplicated chromosomes by pulling them apart to opposite poles during mitosis and meiosis.
- Mitochondria:
- Provides energy (in the form of ATP) required for various cellular processes, including cell division.
- Supports the synthesis of materials needed for cell division, ensuring the proper functioning of the dividing cell.
