Mitosis

Pregunta	Respuesta
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. Image: c09c31f0-83c9-432f-938a-01abdf76d971 (image/png)
Stage 1: Prophase [Late]	Spindle fibres appear. The chromatids start to migrate towards the equator of the cell. Image: d3f5a43e-30c5-4b69-944a-1089e5423774 (image/jpg)
Stage 2: Metaphase (Meta - After)	The chromatids align at the centre. Each gets attached to a spindle fibre by it's centromere. Image: 5146466d-5321-4741-8c3b-69e03c3e3ef1 (image/jpg)
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. Image: 554c84b7-58f9-48e8-a0d5-80b59f649b7b (image/jpg)
Stage 4: Telophase	The spindle fibres disappear. The cleavage appears and the nucleoli reappear. Image: d76c2f4c-3c8e-4fb7-b85f-d9e2a762b1bf (image/jpg)
Stage * : Cytokinesis (Cell movement)	The cells move apart from each other and separate. Image: 2b6ebd44-f8b8-4b9a-99f1-6d2a3d2b8951 (image/jpg)
Significance of Mitosis:	Growth Repair Replacement Reproduction These are also the reasons for why new cells need to be produced.
