| . 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 |
