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.

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:
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:
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:
9. Match items in Column I with Column II:
Column I | Column II |
(a) Bud | (iii) Yeast |
(b) Eyes | (v) Potato |
(c) Fragmentation | (ii) Spirogyra |
(d) Wings | (i) Maple |
(e) Spores | (iv) Bread mould |
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
S. No. | Name of Plant | Agent of Dispersal | Part Helping Dispersal |
1 | Maple | Wind | Winged seeds |
2 | Coconut | Water | Fibrous outer coat |
3 | Xanthium | Animals | Spiny seeds with hooks |
4 | Balsam | Explosion | Fruit bursts open |
5 | Sunflower | Wind | Hairy fruit |
6 | Mango | Animals (Humans) | Edible fleshy fruit |
7 | Pea | Explosion | Dry pod |
8 | Aak (Madar) | Wind | Hairy seeds |
9 | Lotus | Water | Floating fruit |
10 | Burdock | Animals | Hooked seeds |
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.

In asexual reproduction, a new plant is formed from a single parent without the use of seeds. Examples include potato (eyes) and yeast (budding).
In sexual reproduction, two parents are involved, and new plants grow from seeds formed after the fusion of male and female gametes. This method occurs through flowers, the reproductive parts of plants.
Pollination is the process of transferring pollen grains from the anther (male part) to the stigma (female part) of a flower. The chapter describes two types:
Pollination is crucial for fertilisation and seed formation.
