Mitosis VS Meiosis

• Cell cycle


  One of the most breathtaking processes that helps the cell to not only grow but also divide
• Phases of the cell cycle

  • Interphase (preparatory phase)
  • M phase (division phase)
• M phase


  Where M stands for either mitosis or meiosis
• Cell decides to undergo mitosis or meiosis


  Depends on various factors and the type of cell undergoing division
• Mitosis


  • Occurs in somatic or body cells
  • Gives rise to somatic cells which are exact copies of the parent cells
• Meiosis

  • Occurs in reproductive cells
  • Gives rise to haploid sperm and egg cells
• Meiosis in males

  Spermatogenesis (sperm production)
• Mitosis


  • Used as a mode of asexual reproduction in lower organisms
• Meiosis


  • Helps in forming gametes for sexual reproduction
• Differences between mitosis and meiosis


  • Mitosis has one cell division, meiosis has two successive cell divisions
  • Mitosis produces two daughter cells, meiosis produces four daughter cells
  • Mitosis produces diploid daughter cells, meiosis produces haploid daughter cells
  • Mitosis produces genetically similar daughter cells, meiosis produces genetically different daughter cells
  • Mitosis has four stages of division, meiosis has eight stages of division
  • Mitosis occurs in all organisms except viruses, meiosis occurs only in plants, animals and fungi
• Differences in stages of mitosis and meiosis

  • Prophase one of meiosis is longer with five sub-stages, prophase of mitosis is shorter
  • Crossing over occurs in prophase one of meiosis, not in mitosis
  • Independent assortment occurs in metaphase one of meiosis, not in mitosis
  • Separation of chromatids occurs in anaphase of mitosis, separation of homologous chromosomes occurs in anaphase one and separation of sister chromatids occurs in anaphase two of meiosis
• Purpose of mitosis


  Helps in the healing and repairing of cells and tissues, responsible for growth and development of the body
• Purpose of meiosis

  Helps in introducing genetic diversity through the production of gametes
• Mitosis occurs in all organisms except viruses.
• Meiosis occurs only in plant, animals, and fungi.
