Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants

Multiple Choice Questions (MCQs)

Question 1: Which of the following doesn't have fibrous root?

(a) Radish
(b) Carrot
(c) Tapioca 
(d) Wheat

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (d) Wheat

Fibrous roots are a type of root system where roots are thin and branch out extensively. Wheat has a fibrous root system, but Radish, Carrot, and Tapioca all have a taproot system, which is a large, central root.

(a) To absorb water and nutrients from the soil
(b) To make food for the plant
(c) To transport water and nutrients to the different parts of the plant
(d) To support the flower

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer: (c) To transport water and nutrients to the different parts of the plant

The main function of the stem is to transport water and nutrients from the roots to other parts of the plant, like the leaves, flowers, and fruits. 

Question 3: Which of the following has tap root?

(a) Grass
(b) Wheat
(c) Maize
(d) Carrot

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (d) Carrot

A taproot system has a primary, thick central root that grows deep into the soil. Carrots are an example of plants with a taproot system. Grass, wheat, and maize have fibrous root systems, which consist of many small, thin roots.

Question 4: Which of the following is the male part of a flower?

(a) Pistil
(b) Stigma
(c) Stamen
(d) Sepals

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (c) Stamen

The stamen is the male reproductive part of a flower. It consists of the anther and the filament. The anther produces pollen grains, which are necessary for fertilization. The pistil, stigma, and sepals are female or non-reproductive parts.

Question 5: Which of the following is the female part of a flower?

(a) Petal
(b) Sepal
(c) Stamen
(d) Ovary

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (d) Ovary

The ovary is the female reproductive part of the flower. It is located at the base of the pistil and contains ovules, which develop into seeds after fertilization. Petals, sepals, and stamen are other parts of the flower that either protect the reproductive organs or are involved in reproduction.

Question 6: Which part of the plant makes food for the plant?

(a) Root
(b) Leaves
(c) Stem
(d) Fruit

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (b) Leaves

Leaves are responsible for making food for the plant through the process of photosynthesis. They use sunlight, water, and carbon dioxide to produce glucose (food) and oxygen. Roots absorb water and nutrients, but do not make food.

Question 7: Which part of the plant prevents soil erosion?

(a) Stem
(b) Flower
(c) Leaves
(d) Root

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- (d) Roots

Roots hold the soil together and prevent it from being washed away by rain or wind. They anchor the plant to the ground and absorb water and nutrients. This helps reduce soil erosion.

Question 8: The process of loss of water by a plant through its leaves is called

(a) Photosynthesis
(b) Condensation
(c) Transpiration
(d) Evaporation

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer – (c) Transpiration

Transpiration is the process by which plants lose water in the form of water vapor through small openings in their leaves called stomata. It helps in cooling the plant and maintaining water and nutrient flow.

Question 9: The process by which plants make their food is called

(a) Photosynthesis
(b) Condensation
(c) Transpiration
(d) Evaporation

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer – (a) Photosynthesis

Photosynthesis is the process where plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This process occurs in the chloroplasts of the leaves and is essential for the plant's growth and energy production.

Answer the following question

Question: 1. Why are stems important for a plant?

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer: Stems support the plant, transport water and nutrients, and in some plants, perform photosynthesis or store food.

Question: 2. What is fibrous root?

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- The bunch of thin fibre-like roots; arising from the base of the stem is called fibrous root.

Question: 3. What is tap roots?

Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants  View Answer

Answer- When as single main root comes out of the base of the stem, it is called tap root.

FAQs on Class 6 Science Chapter 4 Extra Question Answers - Getting to Know Plants

1. What are the main parts of a plant?
Ans. The main parts of a plant include the roots, stem, leaves, flowers, and fruits. Each part has a specific function: roots anchor the plant and absorb water and nutrients, the stem supports the plant and transports substances, leaves carry out photosynthesis, flowers are involved in reproduction, and fruits contain seeds.
2. How do plants make their food?
Ans. Plants make their food through a process called photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide from the air, and water from the soil to produce glucose (a type of sugar) and oxygen. This process mainly takes place in the leaves, where chlorophyll captures sunlight.
3. Why are roots important for plants?
Ans. Roots are important for plants because they anchor the plant in the soil, preventing it from being uprooted by wind or rain. Additionally, roots absorb water and essential nutrients from the soil, which are necessary for the plant's growth and development.
4. What are the different types of leaves?
Ans. Leaves can be classified into different types based on their shape, size, and arrangement. Common types include broad leaves, needle-like leaves, and compound leaves. Each type is adapted to the plant's environment and helps in maximizing photosynthesis.
5. How do flowers contribute to plant reproduction?
Ans. Flowers play a crucial role in plant reproduction as they contain the reproductive organs of the plant. The male part (stamen) produces pollen, while the female part (pistil) contains the ovary, which develops into fruit after fertilization. Flowers attract pollinators like bees and butterflies, aiding in the transfer of pollen for fertilization.
