Cell Cycle

varioius phases of cell cycle and definitions

The Cell Cycle a regular sequence of growth and division that cells go through; allows you to regenerate tissue and grow
Interphase the longest part of the Cell Cycle, where the cell grows it its full size, DNA replicates (doubles) they spend 90% of the Cell Cycle in Interphase
Mitosis the division of the nucleus; broken into 4 parts: Prophase, Metaphase, Anaphase, and Telophase
Prophase the first part of Mitosis; chromatin condenses (coils) into chromosomes, the nuclear membrane disappears, and spindle fibers form
Metaphase the second part of Mitosis; spindle fibers attach to centromeres and chromosomes line up down the middle of the cell
Anaphase the third part of Mitosis; spindle fibers that were attached to the centromeres pull apart the sister chromatids; other spindle fibers stretch the cell
Telophase the last part of Mitosis; the nuclear membrane reforms within each newly-formed daughter cell, chromatids uncoil into chromatin, and Cytokinesis begins
Cytokinesis the division of the cytoplasm; begins during Telophase; for animal cells, a furrow forms that bundles the spindle fibers into a stem body that is pinched in two when the cell is pinched in two daughter cells
Chromosome A tightly coiled form of DNA found during Mitosis
Chromatid ½ of a chromosome
furrow the segment of an animal cell that results from the pinching in of the parent cell during Cytokinesis
stem body the bundle of spindle fibers that is created by the furrow during Cytokinesis in animal cells
vesicle a temporary organelle in plant cell Cytokinesis that contains cell wall and cell membrane material
cell plate the result of vesicles fusing together in plant cell Cytokinesis
