FAQs on Reproduction In Flowering Plants MCQs With Answers and Explanations
1. What is reproduction in flowering plants?
Reproduction in flowering plants is the process by which angiosperms produce new individuals through sexual or asexual methods. In sexual reproduction, it involves the formation and fusion of male and female gametes inside the flower.
- The flower is the reproductive organ of angiosperms.
- It includes male parts (stamen) and female parts (pistil/carpel).
- Fertilization leads to the formation of a seed and later a fruit.
2. What are the main parts of a flower involved in reproduction?
The main reproductive parts of a flower are the stamen (male) and the pistil or carpel (female).
- Stamen consists of anther and filament; the anther produces pollen grains.
- Pistil consists of stigma, style, and ovary.
- The ovary contains ovules, which develop into seeds after fertilization.
3. What is pollination in flowering plants?
Pollination is the transfer of pollen grains from the anther to the stigma of a flower. It is the first step in sexual reproduction in flowering plants.
- It may occur within the same flower (self-pollination).
- Or between different flowers of the same species (cross-pollination).
- Agents include wind, water, insects, birds, and animals.
4. What is the difference between pollination and fertilization?
Pollination is the transfer of pollen to the stigma, whereas fertilization is the fusion of male and female gametes inside the ovule.
- Pollination: Physical transfer of pollen grains.
- Fertilization: Fusion of male gamete with egg cell.
- Pollination occurs before fertilization.
- Fertilization leads to the formation of a zygote.
5. What is double fertilization in flowering plants?
Double fertilization is a unique process in angiosperms where two fusions occur inside the embryo sac. It is a characteristic feature of flowering plants.
- One male gamete fuses with the egg to form a zygote (syngamy).
- The other male gamete fuses with two polar nuclei to form endosperm (triple fusion).
- The endosperm provides nutrition to the developing embryo.
6. What happens after fertilization in flowering plants?
After fertilization, the zygote develops into an embryo, and the ovule and ovary transform into seed and fruit respectively.
- Zygote → develops into embryo.
- Ovule → becomes seed.
- Ovary → develops into fruit.
- Endosperm provides nourishment to the embryo.
7. What is self-pollination and cross-pollination?
Self-pollination is the transfer of pollen within the same flower or plant, while cross-pollination occurs between different plants of the same species.
- Self-pollination: Occurs in bisexual flowers; less genetic variation.
- Cross-pollination: Requires pollinating agents; increases genetic diversity.
- Cross-pollination leads to stronger and more adaptable offspring.
8. What is the structure and function of a pollen grain?
A pollen grain is the male gametophyte of flowering plants that carries the male gametes. It plays a vital role in fertilization.
- It has a protective outer wall called exine.
- The inner wall is called intine.
- It contains a generative cell and a vegetative cell.
- After pollination, it forms a pollen tube to deliver male gametes to the ovule.
9. What is the role of the ovule in flowering plants?
The ovule is the structure inside the ovary that contains the female gametophyte and develops into a seed after fertilization.
- It contains the embryo sac.
- The embryo sac has the egg cell, synergids, antipodals, and polar nuclei.
- After fertilization, the ovule transforms into a seed.
10. What are the types of asexual reproduction in flowering plants?
Asexual reproduction in flowering plants occurs through vegetative propagation without the formation of seeds. It produces genetically identical offspring.
- Natural methods: Runner (strawberry), rhizome (ginger), tuber (potato), bulb (onion).
- Artificial methods: Cutting, layering, grafting, tissue culture.
- No fusion of gametes occurs in this process.
