| cell cycle | series of events from one cell division to another |
| interphase | phase of growing and working |
| % of time of a cell in interphase | 90% |
| What also happens during interphase | cell makes copies of the organelles |
| chromosome and its copy | sister chromatids |
| parent cell divides into | two identical daughter cells |
| 2 process of cell division | mitosis and cytokinesis |
| during mitosis the cell | divides the nuclear material |
| during cytokinesis | divides the cytoplasm and organelles in half |
| stages of mitosis | P M A T |
| during prophase 1 | chromatids are visible under the microscope |
| during prophase 2 | chromatids look like an X |
| during prophase 3 | nuclear membrane breaks |
| during prophase 4 | in animal cells centrioles move to opposite sides |
| during prophase 5 | spindle fibres are formed |
| during metaphase 1 | sister chromatids attach to the spindle |
| during metaphase 2 | sister chromatids line along the middle |
| during anaphase 2 | chromatids are called chromosomes again |
| during anaphase 1 | sister chromatids move to opposite poles of the cell |
| during telophase 1 | two nuclear membranes form, spindle disappears |
| during telophase 2 | chromosomes get thinner and nucleoli reappear |
| during cytokinesis | divides the cytoplasm in two |
| cytokinesis plant cells | a cell plate is formed and becomes a cell wall |
