Extra 30 short questions and answers from Chapter:7 Getting to Know Plants for Class 6 CBSE Science:-

1. What are herbs? Give examples.

Ans: Herbs are small plants with soft, green, and tender stems. They usually live for a short duration.
Examples: Mint, Coriander, Spinach.

 

2. What are shrubs? Give two examples.

Ans: Shrubs are medium-sized plants with woody stems and branches close to the ground.
Examples: Rose, Hibiscus.

 

3. What are trees? Give two examples.

Ans: Trees are tall plants with a thick, woody trunk and many branches. They live for many years.
Examples: Mango, Neem.

 

4. What are climbers? Give two examples.

Ans: Climbers are weak-stemmed plants that need support to grow upwards.
Examples: Money plant, Pea plant.

 

5. What are creepers? Give examples.

Ans: Creepers are weak-stemmed plants that spread along the ground.
Examples: Pumpkin, Watermelon.

 

6. What is a root? Name its types.

Ans: The root is the part of a plant that grows underground and helps in absorption and anchoring.
Types: Taproot and Fibrous root.

 

7. What is a taproot? Give examples of plants having taproots.

Ans: A taproot is a single, main root with smaller side roots branching out.
Examples: Mango, Pea, Carrot.

 

8. What is a fibrous root? Give examples.

Ans: A fibrous root consists of many thin, bushy roots that arise from the base of the stem.
Examples: Grass, Wheat, Rice.

 

9. What is the function of roots in a plant?

Ans:

Roots absorb water and minerals from the soil.

They anchor the plant in the soil.

Some roots store food (e.g., Carrot, Beetroot).

 

10. What is a stem? Write its two functions.

Ans: The stem is the main structure of the plant that supports branches, leaves, and flowers.
Functions:

It transports water and nutrients from roots to other parts.

It supports the plant and keeps it upright.

 

11. What are the functions of leaves in a plant?

Ans:

Leaves perform

photosynthesis

(prepare food).

They help in

transpiration

(loss of water).

They allow

exchange of gases

through stomata.

 

12. What is photosynthesis?

Ans: Photosynthesis is the process by which green plants make their own food using sunlight, water, and carbon dioxide.

 

13. What are stomata?

Ans: Stomata are tiny pores present on the surface of leaves that help in gas exchange and transpiration.

 

14. What are veins in a leaf? What is their function?

Ans: Veins are thread-like structures in a leaf that transport water, minerals, and food.

 

15. What is transpiration?

Ans: Transpiration is the process of water loss in the form of vapor from the leaves of a plant.

 

16. What are the main parts of a flower?

Ans:

Sepals

– Protect the flower bud.

Petals

– Attract pollinators.

Stamens

– Male part, produces pollen.

Carpel (Pistil)

– Female part, develops into fruit.

 

17. What is pollination?

Ans: Pollination is the transfer of pollen from the stamen (male part) to the carpel (female part) of a flower.

 

18. What is the function of petals in a flower?

Ans: Petals are colorful parts of a flower that attract insects for pollination.

 

19. What is the function of sepals in a flower?

Ans: Sepals protect the flower in its bud stage.

 

20. What is the function of the pistil in a flower?

Ans: The pistil is the female part of a flower that receives pollen and develops into fruit after fertilization.

 

21. What are the two main types of leaf venation?

Ans:

Reticulate venation

– Veins form a network (e.g., Mango,

Peepal

).

Parallel venation

– Veins run parallel (e.g., Grass, Banana).

 

22. What are the two types of root systems?

Ans:

Taproot system

(e.g., Mango, Pea).

Fibrous root system

(e.g., Grass, Wheat).

 

23. What happens when we keep a leaf in sunlight for a few hours?

Ans: The leaf will prepare food using photosynthesis, and starch will be stored in it.

 

24. What is the difference between simple and compound leaves?

Ans:

Simple leaf

– A leaf with a single blade (e.g., Mango).

Compound leaf

– A leaf divided into smaller leaflets (e.g., Neem).

 

25. What is the difference between reticulate and parallel venation?

Reticulate Venation	Parallel Venation
Veins form a network	Veins run parallel
Example: Mango	Example: Grass

 

26. What is the function of the stem in a plant?

Ans:

Supports leaves, flowers, and fruits.

Transports water and nutrients.

 

27. What is the difference between monocot and dicot plants?

Monocot Plants	Dicot Plants
One seed leaf	Two seed leaves
Parallel venation	Reticulate venation
Example: Grass	Example: Mango

 

28. What is germination?

Ans: Germination is the process by which a seed develops into a new plant under suitable conditions.

 

29. How does the stem help in the movement of substances in a plant?

Ans: The stem contains xylem (transports water) and phloem (transports food).

 

30. Why do some plants have modified roots? Give examples.

Ans: Some plants store food in roots.
Examples: Carrot, Radish, Beetroot.
