BIOLOGY
Board – ICSE Class – 10 Topic – Structure of Chromosome
1. How does colchicine act as mitotic poison? Is there any advantage of it?
2. Explain the significance of mitosis.
3. Why is meiosis referred to as reduction division?
4. What is the importance of meiosis in creating variations?
5. State how meiosis maintains chromosome number in a species.
6. What is the importance of meiosis?
7. Give Reason. Gametes must be produced by meiosis for sexual reproduction.
8. Give Reason. Chromosomes are the carriers of heredity.
9. Differentiate between Anaphase of Mitosis and Anaphase of Meiosis-I.

(iii) With reference to cell division explain the following terms: (Chromatid, Centromere,
and Haploid).
(iv) Name the type of cell division that occurs during:
1. Growth of shoot
2. Formation of pollen grains.
3. Repair of worn out tissues.
15. Draw a well labeled diagram to show the anaphase stage of mitosis in a plant cell having
four chromosomes.
