mitosis and meiosis

• What is cell division?

  Cell division is a fundamental biological process where a parent cell divides to produce two or more daughter cells.
• Why is cell division essential for living organisms?

  It is essential for growth, repair, and reproduction.
• What is a parent cell?

  A parent cell is the original cell that divides during cell division.
• What are the two main types of cell division?

  The two main types of cell division are mitosis and meiosis.
• What are chromosomes?


  Chromosomes are structures containing genetic material that are duplicated and distributed during cell division.
• What are daughter cells?

  Daughter cells are the resulting cells after cell division.
• What is mitosis?


  Mitosis is a type of cell division that results in two genetically identical daughter cells from one parent cell.
• What are the key stages of mitosis?

  The key stages of mitosis are prophase, metaphase, anaphase, and telophase.
• What happens during metaphase of mitosis?

  During metaphase, chromosomes align at the cell's equator.
• What happens during prophase of mitosis?

  During prophase, chromosomes condense and become visible.
• What happens during anaphase of mitosis?

  During anaphase, sister chromatids separate and move to opposite poles.
• In which types of cells does mitosis occur?

  Mitosis occurs in somatic (body) cells.
• What happens during telophase of mitosis?

  During telophase, nuclear membranes reform around the new sets of chromosomes.
• What is the result of mitosis?

  The result of mitosis is two diploid cells with the same number of chromosomes as the parent cell.
• If a human cell with 46 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?

  Each daughter cell will have 46 chromosomes.
• A skin cell with 46 chromosomes undergoes mitosis. How many total chromosomes will be present in the two daughter cells combined?

  The total number of chromosomes will be 92.
• A liver cell with 46 chromosomes undergoes mitosis. How many chromosomes will be in each daughter cell?


  Each daughter cell will have 46 chromosomes.
• What is meiosis?


  Meiosis is a type of cell division that produces four genetically diverse daughter cells, each with half the number of chromosomes as the parent cell.
• If a skin cell has 46 chromosomes and a muscle cell has 46 chromosomes, how many chromosomes will be in each daughter cell after these cells undergo mitosis?

  Each daughter cell will have 46 chromosomes.
• In which process does meiosis occur?

  Meiosis occurs in the formation of gametes (sperm and egg cells).
• What are the key features of meiosis?

  The key features of meiosis are two rounds of cell division, crossing over, and reduction division.
• What are the stages of meiosis?

  The stages of meiosis are Meiosis I (Prophase I, Metaphase I, Anaphase I, Telophase I) and Meiosis II (Prophase II, Metaphase II, Anaphase II, Telophase II).
• If a human cell with 46 chromosomes undergoes meiosis, how many chromosomes will each gamete have?

  Each gamete will have 23 chromosomes.
• What is the purpose of meiosis?

  The purpose of meiosis is to produce gametes for sexual reproduction and to increase genetic diversity.
• What is the importance of mitosis?

  The importance of mitosis includes growth, repair, and asexual reproduction.
• How does meiosis contribute to genetic diversity?

  Meiosis contributes to genetic diversity through crossing over and independent assortment of chromosomes.
• How do mitosis and meiosis maintain genetic stability?

  Mitosis preserves genetic information, while meiosis introduces controlled variation.
• In which scenario would meiosis be more important than mitosis?

  Meiosis is more important in the production of sperm cells in human testes.
• What is the importance of meiosis?

  The importance of meiosis includes producing gametes for sexual reproduction, increasing genetic diversity, and facilitating evolution.
• How many stages are there in mitosis?

  4 stages plus interphase

  
• What is the purpose of mitosis in the cell cycle?

  Cellular proliferation

  
• What is the ploidy of the daughter cells produced by mitosis?

  Diploid

  
• What happens to genetic variation during mitosis?


  Genetic variation doesn't change

  
• In which cells does mitosis occur?

  Somatic cells

  
• What happens to chromosome number during meiosis?

  The chromosome number is halved in each daughter cell

  
• What is the ploidy of the daughter cells produced by meiosis?

  Haploid

  
• How many diploid daughter cells are produced by mitosis?

  2 diploid daughter cells

  
• How does meiosis affect genetic variation?

  Genetic variation is increased

  
• What are the key outcomes of mitosis and meiosis in terms of daughter cell number and genetic variation?

  Mitosis:

  • Produces 2 diploid daughter cells
  • Chromosome number remains the same
  • Genetic variation doesn't change

  
  

  Meiosis:

  • Produces 4 haploid daughter cells
  • Chromosome number is halved
  • Genetic variation is increased

  
• What happens to the chromosome number during meiosis?

  The chromosome number is halved in each daughter cell
