words only definitions & notes
  1. cytokinesis
    organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  2. daughter cell
    a cell formed by the division or budding of another cell
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  3. telophase
    the final stage of cell division
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  4. kinetochore
    a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
    Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
  5. microtubule
    a microscopically small tubule
    The cell may contain a pair of centrioles (or microtubule organizing centers in plants) both of which are organizational sites for microtubules.
  6. metaphase
    the second stage of meiosis
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  7. mitosis
    the process by which a cell divides into two new cells
    What is (and is not) mitosis?
  8. prophase
    the first stage of meiosis
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  9. anaphase
    cell division stage wherein chromosomes diverge
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  10. mitotic
    of or relating to or undergoing mitosis
    Some fibers cross the cell to form the mitotic spindle.
  11. chromosome
    a threadlike strand of DNA that carries genes
    Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible.
  12. nucleolus
    a round body in a cell that is involved in protein synthesis
    Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible.
  13. plant cell
    a cell that is a structural and functional unit of a plant
    In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells.
  14. cell nucleus
    a part of the cell containing DNA and RNA and responsible for growth and reproduction
    Metaphase
    Metaphase


    Spindle fibers align the chromosomes along the middle of the cell nucleus.
  15. synthesize
    combine and form a complex whole
    In plant cells, the rigid wall requires that a cell plate be synthesized between the two daughter cells.
  16. chromatin
    the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins; during mitotic division it condenses into chromosomes
    Prophase
    Prophase


    Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes.
  17. spindle
    a stick or pin used to twist the yarn when making thread
    Some fibers cross the cell to form the mitotic spindle.
  18. nucleus
    a part of the cell responsible for growth and reproduction
    Chromosomes are not clearly discerned in the nucleus, although a dark spot called the nucleolus may be visible.
  19. cell
    the basic structural and functional unit of all organisms
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  20. actin
    one of the proteins into which actomyosin can be split
    Cytokinesis
    Cytokinesis


    In animal cells, cytokinesis results when a fiber ring composed of a protein called actin around the center of the cell contracts pinching the cell into two daughter cells, each with one nucleus.
  21. metabolic
    of or relating to metabolism
    Interphase & mitosis
    Interphase
    Interphase


    The cell is engaged in metabolic activity and performing its prepare for mitosis (the next four phases that lead up to and include nuclear division).
  22. condense
    cause a gas or vapor to change into a liquid
    Prophase
    Prophase


    Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes.
  23. protein
    an organic compound essential to living cells
    Proteins attach to the centromeres creating the kinetochores.
  24. microscope
    magnifier of the image of small objects
    Prophase
    Prophase


    Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes.
  25. membrane
    a sheet of tissue that lines or connects organs or cells
    Prometaphase
    Prometaphase


    The nuclear membrane dissolves, marking the beginning of prometaphase.
  26. interaction
    mutual or reciprocal dealings or influence
    Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
  27. nuclear
    constituting the core or central part
    Mitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase.
  28. polar
    of or existing within the Arctic or Antarctic Circles
    Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
  29. physical
    involving the body as distinguished from the mind or spirit
    Motion results from a combination of kinetochore movement along the spindle microtubules and through the physical interaction of polar microtubules.
