. Binary fission | the division of a prokaryotic cell into two offspring cells. Consists of 3 general stages. |
Mitosis | eukaryotic nuclear division |
Meiosis | process of nuclear division that reduces the number of chromosomes in a cell by half. |
Cell cycle | the events of cell division includes interphase, mitosis, and cytokinesis |
Interphase | a period of cell growth and development that precedes eukaryotic cell nuclear division. |
M phase | the phase of cell division in which the nucleus divides |
Cytokinesis | the division of the cytoplasm of one cell into two new cells |
G1 phase | offspring cells grow to mature size |
S phase | during this phase the cell’s DNA is copied |
G2 phase | represents the time gap following DNA synthesis (S phase) this is where the cell prepares for cell division |
G0 phase | cells do not copy their DNA and do not prepare for cell division |
Centrosomes | a dark body containing a centriole in animal cells, not in plant cells.spindle fibers radiate from the centrosome in preparation for mitosis/ |
Centrioles | a structure that appears during mitosis in animal cells |
Spindle fibers | made of microtubules radiate from the centrosomes in preparation for mitosis. |
Mitotic spindle | the array of spindle fibers that serve to divide the chromatids during nuclear division |
Kinetochore fibers | a spindle fiber that extends from the centrosome at one pole of the cell to a chromatid during mitosis |
Kinetochore | a disk shaped protien |
Polar fibers | extend across the dividing cell from one centrosome to the other centeosome |
Metaphase | the 2nd phase of mitosis |
Prophase | the first phase of mitosis |
Anaphase | the phase of mitosis and meiosis in which the chromosomes separate |
Telophase | the final stage of mitosis during which a nuclear membrane forms around each set of new chromosomes |
Cleavage furrow | the area of the cell membrane that pinches in and eventually separates the dividing cell. |
Cell plate | a membrane that divides newly forming plant following mitosis |
