Mitosis and Meiosis

• What are the two types of cell division mentioned in the study material?

  Mitosis and meiosis
• What is the primary purpose of mitosis?

  To produce identical diploid cells for growth and repair
• What type of cells does meiosis produce?

  Varied haploid gametes
• How does the process of mitosis differ from meiosis in terms of the cells produced?

  Mitosis produces identical diploid cells, while meiosis produces varied haploid gametes
• How many cells are produced at the end of meiosis?

  Four haploid cells
• What is the significance of genetic variation in meiosis?

  It arises from random fertilization and chromosome mixing, ensuring offspring differ
• What is the role of mitosis in the body?

  It is crucial for growth, repair, and asexual reproduction
• What are the key steps involved in the mechanism of mitosis?

  • DNA replication
  • Splitting of the cell
  • Producing two genetically identical diploid cells
  • Essential for growth and tissue repair
• How does meiosis ensure that gametes have half the chromosome number needed for fertilization?

  Meiosis creates haploid cells through two divisions
• What role does recombination play in meiosis?

  It introduces genetic diversity, ensuring varied traits in offspring
