| Question | Answer |
| MITOSIS | The cell division in which one parent cell divides into two identical daughter cells. |
| Interphase: | It is a phase in which the cells rest, since no apparent change in chromosomes is visible externally. |
| Stage 1: Prophase ( Pro - first) [Early] | The chromosomes duplicate to form chromatids. The centrosomes duplicate to form centrioles. |
| Stage 1: Prophase [Late] | Spindle fibres appear. The chromatids start to migrate towards the equator of the cell. |
| Stage 2: Metaphase (Meta - After) | The chromatids align at the centre. Each gets attached to a spindle fibre by it's centromere. |
| Stage 3: Anaphase (Ana - back) | The chromatids separate back into chromosomes and start moving 'back' to the poles of the cell by the contraction of the spindle fibres. |
| Stage 4: Telophase | The spindle fibres disappear. The cleavage appears and the nucleoli reappear. |
| Stage * : Cytokinesis (Cell movement) | The cells move apart from each other and separate. |
| Significance of Mitosis: | Growth Repair Replacement Reproduction These are also the reasons for why new cells need to be produced. |
