                Cell Growth and Division (chapter 10)
                The third phase of mitosis, during which the chromosome pairs separate and
 Anaphase
                move toward opposite poles.
  Cancer        Disorder in which some of the body's own cells lose the ability to control growth.

 Cell Cycle     Series of events that cells go through as they grow and divide.

Cell Division   Process by which a cell divides into two new daughter cells.
                One of two tiny structures located in the cytoplasm of animal cells near the
 Centriole
                nuclear envelope. Anchors spindle fibers during cell division.
Centromere      Area where the chromatids of a chromosome are attached.

 Chromatid      One-of-two identical "sister" parts of a duplicated chromosome.
                One of a family of closely related proteins that regulate the cell cycle in
   Cyclin
                eukaryotic cells.
                Phase of the cell cycle where the cell spends most of it's time growing and
 G1 Phase
                performing it's specified job.
 G2 Phase       Shortest of all the phases in interphase.
                Longest phase of the cell cycle (G1, S, G2). Period of the cell cycle between cell
Interphase
                divisions.
  Mitosis       Part of eukaryotic cell division during which the cell nucleus divides.

  M-Phase       The 4th phase of the cell cycle, where mitosis and cytokinesis occur.
                    First and longest phase of mitosis (50% - 60% of total time), during which the
    Prophase        chromosomes condense and become visible and the centrioles separate and take
                    up positions on opposite sides of the nucleus.
Sister Chromatids   Two identical copies of a chromosome that are attached at the centromere.
                    The 2nd stage of the cell cycle, where chromosomes (DNA and proteins) are
     S-Phase
                    duplicated.
                    Fan-like microtubule structure that helps separate the chromosomes during
     Spindle
                    mitosis.
   Stem Cells       An unspecialized cell that gives rise to differentiated cells.

 Surface-area-to-
                    The comparrison of the growth rate of surface area and the volume of cells
  Volume Ratio
                    Fourth and final stage of mitosis, during which the chromosomes begin to
   Telophase
                    disperse into a tangible of dense material (chromatin).
