(c) Fruit

Answer:

1.Answer: (b) stem

Explanation: Potato is the underground modification of stem. It is called as stem tuber. Potato reproduces asexually by the process of vegetative propagation.

2. Answer: (a) Bryophyllum

Explanation:  In bryophyllum Plant buds are present on the margin of leaves.

3. Answer: (c) budding

Explanation:  Binary fission is the process of parent cell splitting into two equal daughter cells. It takes place in prokaryotes (bacteria and archaea) only.
Budding is the process similar to binary fission the daughter cells grow from the parent's body and are detached to form separate individuals in time. The offsprings are always smaller than the parents. This method is observed in yeast along with lower multicellular life forms like hydra.Spore formation or sporogenesis takes place in many multicellular organisms via mitosis and meiosis cell cycles. Spores formed develop into haploid (meiosis) or diploid (mitosis) individuals after dispersion. This method is even found in conidium fungi (not yeast).

4. Answer: (c) Fragmentation

Explanation:  In Spirogyra, asexual reproduction takes place by fragmentation.

5. Answer: (a) winged seeds 

Explanation:  Seeds of maple and drumstick have wings. The winged seeds help them to travel long distances by wind. Seeds of drumstick and maple have wings which help them to be easily carried away by wind.

6. Answer: (c) the bud is to Bryophyllum leaf

Explanation:  Each tuber or potato has several buds. These are the small sprouts we call potato “eyes." It's from these buds that new potato plants can grow. So even though a potato's eyes can't help it see underground, they can help grow more potatoes.

7. Answer: (c) the bud is to Bryophyllum leaf

Explanation:  In an ovary, the numbers of ovules are not equal for every flower. There can be a single or many ovules present in flower.

8. Answer: (c) transfer of pollen from anther to stigma

Explanation:  The transfer of pollen grains from the anther to the stigma is called pollination.

9. Answer: (a) Reproduction

Explanation:  The production of new individuals from their parents is known as Reproduction.

10. Answer: (c) Stamen 

Explanation: stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.

11. Answer: (a) Fern

Explanation:  Ferns and horsetails have two free-living generations: a diploid sporophyte generation (spore-producing plant) and. a haploid gametophyte generation (gamete-producing plant).

12. Answer: (a) Unisexual flowers 

Explanation:  Stamen (filament and an anther) is the male part and the pistil (stigma, style, and the ovary) is the female part of a flower. Note: Lily, rose, sunflower, mango, etc. are bisexual flowers while papaya, snake guard, bitter guard, cucumber, and watermelon flowers are unisexual flowers.

13. Answer: (c) Zygote

Explanation:  During the process of fertilization, a series of reactions triggers the fusion of gametes to produce a diploid cell called a zygote.

14. Answer: (c) pollination

Explanation: The transfer of pollen grain from the anther to the stigma of a pistil is called pollination.

15. Answer: (d) continue the species forever 

Explanation:  Reproduction is essential for all organisms for continuation of the species generation after generation and to maintain a steady species population, so that, it does not become extinct

16. Answer: (d) an embryo

Explanation:  First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.

17. Answer: (c) stem cuttings

Explanation:  Rose and lemon are grown from stem cutting.

18.Answer: (c) with smell and nectar

Explanation: Dates, rambutan, sea grapes, sea holly, tamarind, raspberry, sunflower, tomatoes are a few examples of plants whose seeds are dispersed by animals and birds.

19. Answer: (a) reproduction

Explanation: The function of a flower is to carry out sexual reproduction in plants through the formation of male and female gametes.

20. Answer: (d) Seed

Explanation: After the process of fertilization, the zygote, in time, differentiates to form an embryo inside the ovule. The ovary matures to turn into the fruit which can either be fleshy or dry, in which the seeds are embedded.
