Access NCERT Solutions for Class 6 Science Chapter 2 (Exercise Questions)

The exercise below will help students in revising the concepts covered in Diversity in the Living World. Through the Diversity in the Living World class 6 solutions, they will know how organisms are classified and their distinctive characteristics.

Question 1. Here are two types of seeds. What differences do you find among the roots and leaf venation of their plants?

Answer:

The first seed given is of wheat, which is one of the most important stable crops worldwide.

Roots: Wheat plants have a fibrous root system. The roots arise from the base of the stem and are thin and spread out in all directions, forming a dense network of small roots.

Leaf Venation: Wheat leaves have parallel venation, in which the veins run parallel to each other in the leaf.

The second seed is kidney beans, which are rich in protein, fiber, and essential minerals.

Roots: Kidney beans have a tap root system, where the primary root grows thicker and deeper, and the small branches arise from this.

Leaf Venation: Kidney bean have reticulate type of leaf venation, where the veins form a network or a web-like structure across the leaf.

Question 2. The names of some animals are given below. Group them based on their habitats. Write the names of aquatic animals in the area marked ‘A’ and terrestrial animals in the area marked ‘B. ’ Enter the names of animals living in both habitats in part C. Horse, Dolphin, Frog, Sheep, Crocodile, Squirrel, Whale, Earthworm, Pigeon, Tortoise

Answer:

A (Aquatic Animals):

• Dolphin

• Crocodile

• Whale

B (Terrestrial Animals):

• Horse

• Sheep

• Squirrel

• Pigeon

• Earthworm

• Tortoise

C (Animals living in both habitats):

• Frog

• Crocodile (can live in both water and on land)

Question 3. Manu’s mother maintains a kitchen garden. One day, she was digging out radishes from the soil. She told Manu that radish is a kind of root. Examine a radish and write what type of root it is. What type of venation would you observe in the leaves of the radish plant?

Answer:

The radish is an example of a taproot. In this, the plant has a thick main root called the primary root and bears many side branches called secondary roots. In the radish plant, it helps in the storage of various sugars and starch, making it an important food source for us.

The leaves of the radish plant show reticulate venation. In which veins are irregularly distributed in the lamina, forming a network. This reticulate venation is mostly found in dicot plants.

Question 4. Look at the image of a mountain goat and a goat found in the plains. Point out the similarities and differences between them. What are the reasons for these differences?

Answer:

Similarities: Given below are some of the similarities found in the mountain goat and the goat found in the plains:

1- Both belong to the same kind of family; that is, both are goats.

2- Mountain goats and goats found in plains are herbivores, meaning they eat grass, leaves, and plants.

3- Both have horns on their head, despite their size and structure.

4- Both the two goats are mammals, meaning they give birth to their young ones and give milk.

Differences: There are some differences between these two types of goats, which are provided here:

1- Mountain goats have thick fur, which protects them from the cold and snow. Goats in the plains have thin fur as it is warm in the plains.

2- Mountain goats live alone or in small groups, whereas the goats in the plains live in larger groups.

3- The size of mountain goats is generally smaller than that of the goats in the plains.

4- Mountain goats can easily climb steep hills, but goats in the plains are more used to grazing on flat ground.

Question 5. Group the following animals into two groups based on any feature other than those discussed in the chapter— cow, cockroach, pigeon, bat, tortoise, whale, fish, grasshopper, lizard.

Answer:

Apart from the feature which is already been discussed in this chapter, we can classify these animals based on the presence or absence of a backbone.

Animals having backbone

• Cow

• Pigeon

• Bat

• Tortoise

• Whale

• Fish

• Lizard

Animals without backbone

• Cockroach

• Grasshopper

Question 6. As the population grows and people want more comfortable lives, forests are being cut down to meet various needs. How can this affect our surroundings? How do you think we can address this challenge?

Answer:

As the population is growing, forests are being cut on a large scale, which is known as deforestation, to meet various needs. Here are some effects of this:

• It leads to soil erosion, which results in the loss of the fertile layer of soil.

• Deforestation also disturbs the habitat of many wild animals, birds, and insects.

• Deforestation may lead to frequent floods as there are no trees and their roots to absorb rainwater.

There are some ways by which we can address this challenge:

• We need to plant trees around us.

• Natural resources like wood can be used carefully.

• By using eco-friendly products that cannot harm the environment.

• Avoid using plastic bags as they do not decompose easily and cause pollution.

Question 7. Analyze the flowchart. What can be examples of ‘A’ and ‘B’?

Answer:

According to the above flow chart, plants having leaves and also the reticulate venation can be the dicot plants as this type of venation is unique in dicot plants.

Plants having leaves but not the reticulate venation must be the monocot plants because this venation cannot be seen in monocot plants.

A- Dicot Plant

B- Monocot Plant

Question 8. Raj argues with his friend Sanjay that the “Gudhal (hibiscus) plant is a shrub.” What questions can Sanjay ask for clarification?

Answer:

Sanjay can ask multiple questions of Raj to clarify his argument. Provided below are some of the questions:

1- What is the definition of shrub?

2- How is a hibiscus plant different from a tree?

3- Can a hibiscus plant grow tall or stay small?

4- Is the hibiscus plant woody or soft?

Question 9. Based on the information in the table, find examples of these plants for each group.

(a) What other similarities do plants of group A have?

(b) What other similarities do plants of group B have?

Answer:

(a) Dicot plants having taproots have some similarities that include the seeds having two cotyledons and reticulate venation found in leaves.

(b) Group B, having Monocot seed and fibrous roots have one cotyledon in their seeds and leaves are having parallel venation.

Question 10. Observe the labelled part of a duck in the picture given below. What differences do you observe in the feet of the duck compared to the other birds? Which activity would the duck be able to perform using this part?

Answer:

The labelled part of the duck is its webbed feet, which are different from the feet of other birds. The toes of ducks have skin in between that form a ‘web, ’ which is not present in other birds. Other ones have individual toes without any skin present.

This helps the duck to swim and move easily in water. When the duck moves with its webbed feet, a lot of water is pushed backward, which allows the duck to move quickly forward; that is why ducks are very good swimmers.

Approach to Solve Class 6 Chapter 2 Questions Effectively

To answer Diversity in the Living World questions, simply apply the following steps:

1. Read the chapter to learn about the diversity and classification of plants and animals surrounding us.

2. Observe and record distinguishing features such as stem type, leaves, flowers, and habitats for classifying organisms.

3. Practice classifying and grouping examples based on similarities and differences between living organisms.

4. Rewrite definitions and key terms such as biodiversity, adaptation, and classification.

5. Study the diversity in the living world, Class 6 NCERT solutions to strengthen the understanding and answer-writing ability.

Important Question from Chapter 2 Class 6

To understand how questions are framed in the exam, it is important to practice questions. Given below is a question along with the answer. More such questions are added in the Diversity in the Living World class 6 NCERT solutions

Question 1: Which of the following is an example of a herb?
a) Mango
b) Mint
c) Rose
d) Neem
Answer: b) Mint

Explanation:

Mint (genus Mentha) is an example of a herb because it is a small, aromatic, and soft-stemmed plant that typically grows close to the ground. Unlike trees such as mango or neem, which have woody stems, herbs like mint have non-woody stems and are often used for culinary, medicinal, and aromatic purposes. Mint plants are perennial herbs known for their distinctive fragrance and are widely used in cooking and herbal remedies. This distinguishes mint clearly as a herb, while mango, rose, and neem are trees or shrubs with woody stems.
