1. One of the following method of reproduction is slow-
1) Vegetative 2) Asexual 3) Sexual 4) 2, 3

2. The significance of reproduction is-
1) Spreading to larger areas 2) Variations
3) Evolution 4) Continuity of species

3. Read the following statements and find out incorrect one-
1) Reproduction always involves 2 plants or parents
2) Reproduction always involves gametic union
3) Reproduction always requires for the union of gamets
4) All are correct

4. Asexual reproduction is common in the following-
1) Organisms with complex organisation
2) Organisms must contain vascular tissues
3) Organisms with simple organisation
4) Highly advanced plants

5. Gamets are not involved in-
1) Sexual reproduction 2) Asexual and vegetative reproduction
3) Budding 4) Sexual and Vegetative

6. The method of reproduction depends on
1) Habitat of the organism 2) Physiology of organism
3) 1 & 2 4) Size of the organisms

7. One of the following is an ephimeral-
1) Wolffia 2) Palm 3) Banana 4) Pinus

8. Offspring exactly resembles gentically and morphologically in asexual or vegetative
reproduction because-
1) It involves only one parent
2) It involves the union between gamets
3) It involves mitosis only
4) It involves meiosis followed by mitosis

9. Clones are formed as a result of-
1) Sexual reproduction 2) Asexual reproduction
3) Vegetative reproduction 4) 2, 3

10. Assertion (A): Vegetative propagules form clones.
Reason (R): They do not show meiosis.
1) A & R are correct. R explains A.
2) A & R are correct. R do not explains A.
3) A is correct. R is false.
4) A is false. R is correct.

11. Spore formation is exogenous-
1) Rhizopus 2) Pencillium 3) Mucor 4) 1, 3

12. Arrange the following plants in ascending order basing on their span of life-
A) Banana B) Pinus C) Wolffia
D) Carrot E) Rose F) Rice
1) D F C E A B 2) C D A F B E 3) C F D A E B 4) D C F A E B

13. Differentiate a spore from zygote-
1) Former undergoes mitosis, later shows either mitosis or meisosis
2) Later undergoes mitosis only, former undergoes mitosis
3) Former undergoes meiosis and the later undergoes mitosis
4) Former and later undergo meiosis

14. The benefit of formation of spores is-
1) These are unicellular and can produce a daughter haploid plant
2) It can produce a new plant
3) These are adopted for dispersal and survive for extended periods of time in unfavourable conditions
4) They have short life span

15. Gametogenesis means
1) Formation of gamets from their precursor cells
2) Union between 2 gamets
3) Union between male gamet and egg cell
4) Formation of gamets from sporophyte

16. Assertion (A): vegetative is also a type of asexual reproduction.
Reason (R): Vegetative reproction do not involves gametic union.
1) A & R are correct. R explains A.
2) A & R are correct. R do not explains A.
3) A is correct. R is false.
4) A is false. R is correct.

17. Formation of seeds without fertisations is called-
1) Apogamy 2) Apomixis 3) Apospory 4) Parthenocarpy

18. Formation of fruit without fertilisation from the ovary is called-
1) Apospory 2) Apogamy 3) Parthenocarpy 4) Apomixis

19. Parthenocarpy do not requires-
1) Pollination 2) Microsporogenesis
3) Megasporogenesis 4) All

20. Apomixis is-
A) Mimics sexual reproduction B) A kind of asexual reproduction
C) A kind of hybridisation D) A kind of vegetative reproduction
1) A B 2) ABC 3) ABCD 4) BC

21. Citrus shows-
1) Polygamous 2) Polyembryony
3) Parthenocarpy 4) Apomixis

22. Match the following
I. Parthenocarpy A) Formation of seed without fertilistion

IV. Embryogeny D) Formation of embryo from nucellar tissue
I II III IV I II III IV
1) C D B A 2) A C D B
3) C D A B 4) D A B C

23. In citrus or Mango additional embryos are formed in the-
1) nucellus 2) embroyosac 3) Fruit 4) Seed

24. Mango shows
A) True embryo in the embryosac
B) Many embryos in nucellus
C) Many embryos in embrysoac along with true embryo
D) Many embryos in the fruit
1) A only 2) A B 3) A C 4) B C D

25. Match the following
I. Grape A) Apomixis
II. Mango B) Parthenocarpic
