Reproduction in Plants Class 7 Science Chapter 8 Worksheet

Reproduction in plants is essential topic in the Class 7 Science syllabus. It explains how plants give rise to new plants of the same kind. Just like humans and animals, plants also have their own ways of reproducing and continuing their life cycle. 

In NCERT Solutions Class 7 Chapter 8 Reproduction in Plants, we learn about different methods like asexual reproduction, sexual reproduction, vegetative propagation, pollination, and seed formation. Now its time to test your knowledge. Infinity Learn has prepared some Class 7 science worksheet questions on Chapter 8 based on NCERT guidelines.

Reproduction in Plants Class 7 Science Chapter 8 

There are numerous ways through which plants can reproduce either through seed or roots, stems or leaves. As an example, parts such as the eye of the potato or a stem of the money plant can produce another plant. 

The other concept that is discussed in the chapter is that flowers are the main reproductive organs of a plant and that the process of pollination and fertilization help in the formation of seeds.

B. Fill in the blanks

• The process of seed formation takes place after fertilization.
• A spore is a single cell capable of growing into a new organism.
• Wind, water, and animals help in seed dispersal.
• Bryophyllum leaves can produce new plants from their edges.
• In yeast, reproduction takes place by budding.

C. Application-Based / HOTS (Higher Order Thinking Skills)

Why do some plants produce flowers while others don’t?
Answer: Flowering plants reproduce sexually through flowers, while others reproduce asexually using parts like roots or leaves.

A gardener cuts a small stem of rose and plants it. The new plant grows exactly like the parent. Why?
Answer: Because vegetative propagation makes a clone of the parent plant.

If pollinators disappear, what will happen to flowering plants?
Answer: Many will fail to produce fruits or seeds, reducing plant reproduction.

D. Activity / Think Zone

Observation Challenge:
Watch a flowering plant in your garden for a week. Write what you observe about flower color, insects visiting it, and any change in the ovary.
Insects visit for nectar; after pollination, petals dry and the ovary becomes fruit.

Creative Question:
Imagine you are a seed carried by wind. Describe your short journey to a new place (in 2-3 lines).
Answer: “I floated high in the air, crossed a pond, and landed on soft soil where I started to grow into a new plant.”

Advanced-Level Questions on Reproduction in Plants (JEE/NEET Pattern Inspired)

1. A gardener removes all flowers from a plant but still observes new plants forming near its roots. What type of reproduction is this?

a) Sexual reproduction
b) Asexual reproduction
c) Cross-pollination
d) Double fertilization
Answer: b) Asexual reproduction
Explanation: The new plants are formed without flowers or seeds, showing vegetative propagation from roots.

2. Which of the following statements best explains why offspring formed by vegetative propagation are genetically identical?

a) They share pollen from the same flower
b) They arise from mitotic cell division only
c) They result from random fertilization
d) They form after cross-pollination
Answer: b) They arise from mitotic cell division only
Explanation: Vegetative propagation involves mitosis, so no genetic variation occurs.

3. In a flower, if both the anthers and stigma mature at different times, it prevents:

a) Cross-pollination
b) Self-pollination
c) Double fertilization
d) Seed formation
Answer: b) Self-pollination
Explanation: This process is called dichogamy and promotes cross-pollination for genetic diversity.

4. A flower is enclosed by green structures that protect it before it opens. These belong to which whorl of the flower?

a) Calyx
b) Corolla
c) Androecium
d) Gynoecium
Answer: a) Calyx
Explanation: The calyx, made of sepals, guards the flower in its bud stage.

5. Why are spores more advantageous than seeds in unfavorable conditions?

Answer: Spores have a tough outer wall that resists heat and dryness, allowing them to survive longer until conditions become suitable.

6. In which situation will vegetative propagation fail?

a) When stem cuttings are too dry
b) When there is excess light
c) When the plant is watered daily
d) When leaves are large
Answer: a) When stem cuttings are too dry
Explanation: Vegetative propagation needs moisture for root development.

7. A scientist removes the anthers from a flower before they mature. What could be his possible aim?

a) To study fertilization
b) To promote cross-pollination
c) To prevent seed germination
d) To stop fruit development
Answer: b) To promote cross-pollination
Explanation: Removing anthers (emasculation) prevents self-pollination and allows controlled cross-pollination.

8. Which of the following is not a form of asexual reproduction?

a) Budding
b) Fragmentation
c) Spore formation
d) Pollination
Answer: d) Pollination
Explanation: Pollination occurs in sexual reproduction, not asexual.

9. A student observed that in one type of plant, new individuals grew from the edges of leaves. Which plant could it be?

a) Potato
b) Bryophyllum
c) Ginger
d) Onion
Answer: b) Bryophyllum
Explanation: Bryophyllum reproduces asexually from leaf margins.

10. During double fertilization in flowering plants, one male gamete fuses with the egg cell. The other fuses with:

a) Another pollen grain
b) Secondary nucleus
c) Embryo
d) Stigma
Answer: b) Secondary nucleus
Explanation: This forms the endosperm, which nourishes the embryo.

11. Which factor plays the most important role in wind pollination?

a) Heavy sticky pollen
b) Bright petals
c) Large quantity of light pollen
d) Nectar secretion
Answer: c) Large quantity of light pollen
Explanation: Lightweight pollen travels easily through wind.

12. Asexual reproduction is faster but produces less diversity. Why is this considered a disadvantage for plants?

Answer: Because all plants become genetically identical, making them vulnerable to diseases or environmental changes.

13. The ovule after fertilization develops into:

a) Fruit
b) Seed
c) Pollen grain
d) Ovary
Answer: b) Seed
Explanation: The ovule becomes a seed, and the ovary becomes fruit.

14. If a plant species stops producing pollen grains, which process will be directly affected?

a) Germination
b) Pollination
c) Seed dispersal
d) Vegetative propagation
Answer: b) Pollination
Explanation: Pollen is necessary for fertilization; without it, pollination cannot occur.

15. A hybrid plant shows features of both parents. Which type of reproduction has occurred?

a) Asexual
b) Sexual
c) Budding
d) Spore formation
Answer: b) Sexual
Explanation: In sexual reproduction, fusion of gametes leads to new combinations of parental traits.
