| Term | Definition |
|---|---|
| Checkpoint 1 & Interphase | Checkpoint checks if the lack of nutrients supports growth and if the DNA is damaged or not |
| Growth phase (G1) | Cell is growing and developing organelles |
| Synthesis phase (S) | Chromosomes replicate in the nucleus (x2), then divide |
| Checkpoint 2 & Growth phase (G2) | Checkpoint checks if the lack of nutrients supports growth and if the DNA is damaged or not, then the cell grows and continues to develop organelles. |
| Prophase | Centrioles move to opposite poles. Nuclear envelope disappears. Chromosomes coil up into visible structures. |
| Metaphase | Spindle fibres attach on the chromosomes (centromere to be specific) and line them up in the middle. |
| Anaphase | Spindle fibres retract and pull half the chromosomes towards each centriole. |
| Telophase | The spindle fibres are back in the centrioles. Nuclear envelope starts to reappear as well as both sets of chromosomes. |
| Cytokinesis (Animals) | Cell membrane pinches off in the middle and separates into 2 daughter cells. |
| Apoptosis | How your body causes certain cells to die on purpose when they’re no longer needed or are damaged. |
| Cancer Cells | Cells keep growing at an unstable rate. |
| Tumor | An example of what cancer cells can cause. |
| Cytokinesis (Plants) | A new cell wall forms called a cell plate along the middle. |
