1. Write any two differences between binary fission in amoeba and budding in yeast.
2. Any two differences between binary fission in amoeba and budding in yeast is shown below in table:

   Binary fission in Amoeba	Budding in yeast
   Here nucleus divides first and then cytoplasm divides.	Here cytoplasm divides first and then nuclear divides.
   Newly formed amoeba separate from each other.	Newly formed yeast remains attached to the parent cell.

3. Write any two difference between male gamete and female gamete.
4. Two difference between male gamete and female gamete is shown below in table:

   Male gamete (Sperm)	Female gamete (Ovum)
   It is produced in testes.	It is produced in ovary.
   It is tailed and is active.	It is without tail and is inactive.

5. Write any two characteristics of sexual reproduction.
6. Two characteristics of sexual reproduction are:
   1. The offspring produced by this method are genetically different from each other or from the parent cell.
   2. The variation caused due to sexual reproduction helps in the organic evolution.
7. Vegetative propagation is beneficial to the farmers, why?
8. Vegetative propagation is beneficial to the farmers because of the following reasons:
   1. It is cheaper, faster and easier method of reproduction.
   2. Plants which do not have good quality seeds like banana, sugarcane, rose, tc. can be reproduced easily and earlier by this method.
   3. Large number of species can be grown from a single individual.
9. Why does the number of chromosomes differ in ovum and zygote?
10. The ovum is formed by the meiosis process. But the zygote is formed by the fusion of male and female gametes. It has double chromosomes than in gametes. So, the number of chromosomes differs in the ovum and zygote.
11. Why do farmers prefer vegetative propagation for farming plants like rose, potato, banana, etc.?
12. Farmers prefer vegetative propagation for farming plants like rose, potato, banana, etc. because they do not have good quality seeds and can be reproduced easily and fast by this method.
13. Number of chromosomes are double in zygote than gametes, why?
14. The ovum is formed by the meiosis process. But the zygote is formed by the fusion of male and female gametes. So, the number of chromosomes is double in zygote than in gametes.
15. Write any two difference between external and internal fertilization with examples.
16. Any two difference between external and internal fertilization with examples are shown below in table:

    External fertilization	Internal fertilization
    Fertilization takes place outside the body of female.	Fertilization takes place inside the womb of female.
    Water medium is essential for this fertilization.	Water medium is not essential for this fertilization.
    For examples: fishes, frogs, etc.	For examples: human beings, etc.

17. Write any two difference between self pollination and cross pollination.
18. The difference between self pollination and cross pollination are shown below in table:

    Self pollination	Cross pollination
    It is the transfer of pollen grain from anther to the stigma of the same flower.	It is transfer of pollen grain from the anther of one flower to the stigma of another flower.
    It does not require an external agency for the transfer of pollen grains.	It requires an external agency for the transfer of pollen grains.
    It does not bring variation.	It brings about large number of variation.

19. What is the role of mitosis cell division in the reproduction process of amoeba?
20. Mitosis cell division helps in the reproduction process of amoeba as it produces an identical copy of the parent cell.
21. Name any two animals which reproduce by regeneration and describe the process also.
22. Animals which reproduce by regeneration are hydra, starfish, tapeworm, planaria, etc. In this process, the body divides into fragments and each fragment develops into a complete organism.
23. Draw the diagram of fertilization process in angiospermic plant and label the parts pollen tube, pollen grain and ovule.
24. Diagram:

    

25. Write any two advantages of vegetative propagation.
26. Any two advantages of vegetative propagation are listed below:
    1. Genetically identical organism are produced by this method.
    2. It is very useful to preserve the plants which are rare and endangered.
