Cell Reproduction

AB
. Binary fissionthe division of a prokaryotic cell into two offspring cells. Consists of 3 general stages.
Mitosiseukaryotic nuclear division
Meiosisprocess of nuclear division that reduces the number of chromosomes in a cell by half.
Cell cyclethe events of cell division includes interphase, mitosis, and cytokinesis
Interphasea period of cell growth and development that precedes eukaryotic cell nuclear division.
M phasethe phase of cell division in which the nucleus divides
Cytokinesisthe division of the cytoplasm of one cell into two new cells
G1 phaseoffspring cells grow to mature size
S phaseduring this phase the cell’s DNA is copied
G2 phaserepresents the time gap following DNA synthesis (S phase) this is where the cell prepares for cell division
G0 phasecells do not copy their DNA and do not prepare for cell division
Centrosomesa dark body containing a centriole in animal cells, not in plant cells.spindle fibers radiate from the centrosome in preparation for mitosis/
Centriolesa structure that appears during mitosis in animal cells
Spindle fibersmade of microtubules radiate from the centrosomes in preparation for mitosis.
Mitotic spindlethe array of spindle fibers that serve to divide the chromatids during nuclear division
Kinetochore fibersa spindle fiber that extends from the centrosome at one pole of the cell to a chromatid during mitosis
Kinetochorea disk shaped protien
Polar fibersextend across the dividing cell from one centrosome to the other centeosome
Metaphasethe 2nd phase of mitosis
Prophasethe first phase of mitosis
Anaphasethe phase of mitosis and meiosis in which the chromosomes separate
Telophasethe final stage of mitosis during which a nuclear membrane forms around each set of new chromosomes
Cleavage furrowthe area of the cell membrane that pinches in and eventually separates the dividing cell.
Cell platea membrane that divides newly forming plant following mitosis
