| Term | Definition |
| Interphase | normal phase, not considered phase of mitosis, period of intense metabolic activity, consists of 3 phases: G1 cell prepares for replication and organellles reproduce, S synthesis of DNA- replication of genetic material, G2 last stage |
| Prophase | nucleus disintegrates, spindle fibers form at two opposite poles, chromatin condenses to form chromosomes, centrioles migrate to poles |
| Metaphase | chromosomes line up in middle of cell, centromeres line up in middle of cell |
| Anaphase | chromosomes (centromeres seperate slowly), arms of chromatids pull centromeres apart, spindle fibers help pull centromeres apart, spindle fibers get shorter and this, most rapid phase |
| Telophase | nucleus starts to form again, cytokinesis occurs and cell divides, two daughter cells are formed identical to the parent cell |
| cytokinesis | organic process consisting of the division of the cytoplasm of a cell following cytokinesis bringing about the separation into two daughter cells |
| cytokinesis: animal cells | the cell membrane squeezes together around the middle of the cell wall |
| cytokinesis: plant cells | cell wall cannot squeeze together in the same way that a cell embrane can |
