Chapter 9: Cell Continuity

  1. What is the term cell continuity?
    Cell continuity: the ability of cells to divide and survive from one generation to the next.
  2. What is a chromosome?
    Chromosome: a structure found in the nucleus containing DNA and proteins.
  3. What two things does the chromosome contain?
    The chromosome is found in the nucleus and contains DNA and proteins.
  4. What is meant when a cell is diploid?
    Diploid cell (2n) has two copies of each chromosome .
  5. What is meant when a cell is haploid?
    Haploid cell (n) contains one copy of each chromosome.
  6. Why is cell division necessary?
    Cell division is necessary for every cell to divide, grow, repair and reproduce.
  7. What are the 2 types of cell division?
    • Mitosis
    • Meiosis
  8. Where does mitosis occur?
    Mitosis occurs in - somatic cells (most animal cells) and growth tips, meristems of plants.
  9. What is meant by somatic cells?
    Most animal cells
  10. Give three points on cell division?
    • It’s necessary for every cell to divide,grow, repair and reproduce.
    • Two types are - mitosis and meiosis.
    • Mitosis occurs in somatic cells (most animal cells) and in growth tips, meristems of plants.
  11. What is the term mitosis?
    Mitosis: the division of a nucleus into two genetically identical copies of itself.
  12. By mitosis, how many daughter cells are produced?
    1 parent cell produces 2 daughter cells in mitosis.
  13. Are the parent cells and daughter cells alike?
    Parent and daughter cells are identical and have same amount of chromosomes each.
  14. When is the division rate faster?
    Division is at a faster rate when younger and slows with age.
  15. Can mitosis occur in haploid or diploid cells?
    Mitosis can occur in haploid or diploid cells.
  16. Give 5 points on mitosis?
    • 1 parent cell produces 2 daughter cells.
    • Both have same amount of chromosomes.
    • Cells are genetically identical.
    • Diploid cells have 46 chromosomes, haploid 23.
    • Division is at a faster rate when younger and slows with age.
