NCERT Solutions for Class 7 Science Chapter 8 – Reproduction in Plants

Have you ever wondered how new plants grow from old ones? In Class 6, we learned that reproduction is a key feature of all living beings—it helps them create more of their own kind. But when it comes to plants, the question is: how do they reproduce? Chapter 8 of Class 7 Science – Reproduction in Plants answers this in a simple and exciting way. 

This chapter covers the different modes of reproduction in plants, including asexual reproduction like budding and fragmentation, and sexual reproduction involving flowers, pollination, and seeds. With the help of NCERT Solutions for Class 7 Science Chapter 8, students can explore these concepts in detail, understand important diagrams, and prepare better for exams. These solutions are based on the latest CBSE syllabus and are designed to make learning easy and interesting.

Class 7 Science Chapter 8 Exercise Solutions

 1. Fill in the blanks:
(a) Production of new individuals from the vegetative part of the parent is called vegetative propagation.
(b) A flower may have either male or female reproductive parts. Such a flower is called unisexual.
(c) The transfer of pollen grains from the anther to the stigma of the same or another flower of the same kind is known as pollination.
(d) The fusion of male and female gametes is termed as fertilisation.
(e) Seed dispersal takes place by means of wind, water, and animals.

2. Describe the different methods of asexual reproduction. Give examples.
Answer:  Asexual reproduction in plants occurs without seeds. The main methods are:

• Vegetative Propagation: It is a form of asexual reproduction in which new plants grow from the vegetative parts of a plant like the root, stem, or leaf, without using seeds. These new plants are usually exact copies of the parent plant.
  Example: Potato (eyes), Bryophyllum (leaf buds), Ginger (stem).
• Budding: A small outgrowth called a bud forms on a parent cell and grows into a new organism.
  Example: Yeast
• Fragmentation: The body of the plant breaks into parts, and each part grows into a new plant.
  Example: Spirogyra (algae)
• Spore Formation: It is a method of asexual reproduction where plants produce tiny, light cells called spores. These spores can survive in harsh conditions and grow into new plants when they get enough moisture, warmth, and nutrients.
  Example: Bread mould, fern

3. Explain what you understand by sexual reproduction.
Answer: In sexual reproduction, a new plant is formed when the male and female gametes combine or join together. The male part (stamen) produces pollen grains, and the female part (pistil) contains ovules. When pollen reaches the stigma, fertilisation occurs, forming a zygote, which grows into a seed.

4. How is asexual reproduction different from sexual reproduction in plants?
Answer:

• In asexual reproduction, a single parent gives rise to new plants without using seeds.
• In sexual reproduction, two parents (male and female) are involved and the plant is formed from seeds after fertilisation.

5. Sketch the reproductive parts of a flower.
Answer: Draw a flower with the following labels:

Stamen (Anther and Filament – Male part)

Pistil (Stigma, Style, Ovary – Female part)

Ovule inside the ovary

6. Explain the difference between self-pollination and cross-pollination.
Answer:  Self Pollination: This occurs when the pollen grains from a flower’s anther reach the stigma of the same flower or another flower on the same plant. It involves only one plant and happens naturally without the need for external help.

Cross-pollination: In this process, pollen is transferred from the anther of one plant to the stigma of a flower on another plant of the same species. It usually requires agents like wind, water, or insects to carry the pollen.

7. How does fertilisation occur in flowering plants?
Answer: Fertilisation in flowers begins when a pollen grain reaches the stigma of a flower. From there, it develops a pollen tube that travels down through the style to reach the ovule inside the ovary. The male gamete moves through this tube and combines with the female gamete present in the ovule. This joining of gametes is called fertilisation. The result of this fusion is a zygote, which later develops into an embryo and eventually forms a seed.

8. Describe the various ways by which seeds are dispersed.
Answer:
Seeds are dispersed by:

• Wind: Seeds are light or have wings/hairs (e.g., maple, aak).
• Water: Seeds float on water (e.g., coconut).
• Animals: Sticky or spiny seeds stick to fur or clothes (e.g., Xanthium).
• Explosion: Some fruits burst and scatter seeds (e.g., castor, balsam).

9. Match items in Column I with Column II:

 10. Tick (✓) the correct answer:

(a) The reproductive part of a plant is the
(iv) flower

(b) The process of fusion of male and female gametes is called
(i) fertilisation

(c) Mature ovary forms the
(iv) fruit

(d) A spore-producing organism is
(ii) bread mould

(e) Bryophyllum can reproduce by its
(ii) leaves

Activity 3: Table of Fruit-bearing Plants and Seed Dispersal

Activity 4: Doubling of Organism through Asexual Reproduction 

If an organism doubles every hour through asexual reproduction, after 10 hours, the number of organisms = 2¹⁰ = 1024 So, 1024 organisms will be present after 10 hours. This group is called a clone, as all individuals are identical copies of the parent.
