20 Cards in this Set

  • Front
  • Back
Chromosome
DNA coiled up in an X shape
Chromatids
Identical chromosome copies
cell cycle
the life cycle of a cell; in eukaryotes it consists of chromosome duplication, mitosis, and cytokinesis
Centromere
Structure that holds the two sister chromatids together
Centriole
Cylinder shaped structure that comes in pairs and holds the spindle fibers
Spindle Fibers
Strings that separate the sister chromatids
Somatic
Body cells
Gametes
Sex cells
Cytokinesis
When the cytoplasm and cell membrane divide to make two new daughter cells
Daughter cells
The cells produced from parent cells in mitosis and meiosis
Interphase
Part of the Cell Cycle where the cell is resting and the DNA is replicating
Prophase
Part of mitosis, where the nuclear membrane begins to disappear, the centrioles move to opposite poles, and the chromosomes become visible
Metaphase
Stage of mitosis where the chromosomes line up in the middle and the spindle fibers attach to them
Anaphase
Stage of mitosis where the sister chromatid are separated by the spindle fibers
Telophase
Stage of mitosis where the nuclear envelope reappears and the cell membrane begins to pinch in
cell plate
wall that builds up between two new plant daughter cells
cytokinesis
When the two daughter cells are formed and the cytoplasm divides
Meiosis
cell division of sex cells where the daughter cells have HALF the # of chromosomes as the parent cell
Mitosis
cell division of body cells where the daughter cells have the SAME # of chromosomes as the parent cell
cell cycle
the life cycle of a cell; in eukaryotes it consists of chromosome duplication, mitosis, and cytokinesis
