प्रश्न
The diagram given below represents a certain stage of mitosis:
- Identify the stage of cell division.
- Name the parts labelled A and B.
- What is the unique feature observed in this stage?
- How many daughter cells are formed from this type of cell division?

उत्तर
- Anaphase
- A - Spindle fibre, B - Centromere
- During this stage (anaphase), the two sister chromatids of each chromosome separate and are drawn towards the opposite poles because of the shortening of spindle fibres.
- This type of cell division (mitosis) results in the formation of two daughter cells.
