Cell division

• What are the main stages of mitosis?

  Prophase, metaphase, anaphase, telophase
• What is the significance of mitosis in life cycles?

  It produces genetically identical cells
• What is a chromatid?

  One of the two strands of a chromosome
• What is cytokinesis?

  Division of the cytoplasm after mitosis
• How does mitosis maintain chromosome number?

  New daughter cells have the same genetic information
• What type of reproduction do single-celled protists like Amoeba use?

  Asexual reproduction through mitosis
• How do strawberries reproduce asexually?

  By runners
• What is the role of growth factors in tissue repair?

  They stimulate cell proliferation to heal wounds
• What is the acronym to remember the stages of mitosis?

  PMAT
• What happens to chromosomes during prophase?

  They thicken and condense
• What forms between centrosomes during mitosis?

  A spindle forms from microtubules
• What is the role of the centromere during mitosis?

  It joins two sister chromatids
• What occurs during anaphase?

  Sister chromatids are pulled apart
• What happens during telophase?

  A new nuclear membrane forms around chromosomes
• What is the result of cytokinesis in animal cells?

  Two genetically identical daughter cells
• How do plant cells undergo cytokinesis?

  By forming a new cell wall between daughter cells
• What is the purpose of squashing root-tip cells for observation?

  To examine stages of mitosis under a microscope
• What happens to chromatids during metaphase?

  They attach to spindle threads at the equator
• What is the definition of haploid?

  Having only one set of chromosomes
• What are homologous chromosomes?

  Matching chromosomes with the same genes
• What is meiosis?

  A type of nuclear division reducing chromosome number
• Why is meiosis significant in life cycles?

  It produces gametes with half the chromosome number
• How does meiosis maintain chromosome numbers in sexually reproducing organisms?

  By producing haploid gametes that fuse during fertilization
• What type of cell division produces male honeybees from unfertilized eggs?

  Parthenogenesis, a form of asexual reproduction
• What is the chromosome number in haploid cells?

  One set of chromosomes, represented by n
• What is the role of alleles in homologous chromosomes?

  They may contain different variants of genes
• What is the difference between haploid and diploid cells?

  Haploid has one set; diploid has two
• What is the significance of meiosis in sexual reproduction?

  It ensures genetic diversity in offspring
• What are the main stages of mitosis?

  Prophase, metaphase, anaphase, telophase
• What is the significance of mitosis in life cycles?

  Mitosis is essential for growth and repair
• What is a chromatid?

  One of the two strands of a chromosome
• What is cytokinesis?

  Division of the cytoplasm after mitosis
• What does mitosis maintain in daughter cells?

  The same chromosome number as the parent cell
• Which organisms primarily use asexual reproduction?

  Some plants and single-celled organisms
• How do strawberry plants reproduce asexually?

  By producing runners that grow new plants
• What is the role of mitosis in tissue repair?

  It stimulates the formation of new cells
• What is the acronym to remember the stages of mitosis?

  PMAT
• What happens to chromosomes during prophase?

  They thicken and condense
• What forms between centrosomes during mitosis?

  A spindle formed from microtubules
• What is the role of centrioles in animal cells during mitosis?

  They help form the spindle structure
