Question

Mention the role of nucleus, centrosome and mitochondria in cell division.

Answer

  1. 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.
  2. 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.
  3. 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.
