1. Here are two types of seeds. What differences do you find
among the roots and leaf venation of their plants?
Answer:
(a) Wheat:
Seed Type: Monocotyledon (Monocot)1
Root System: Fibrous roots2
Leaf Venation: Parallel venation2
(b) Kidney Beans:
Seed Type: Dicotyledon (Dicot)1
Root System: Taproot system3
Leaf Venation: Reticulate venation3
Question 2: 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:
Aquatic animals (A) = Dolphin and Whale
Terrestrial animals (B) = Horse, Sheep, Squirrel, Pigeon and Earthworm.
Animals living on land and sea both (C) = Frog, Tortoise and Crocodile .
Question 3: Manu’s mother maintains a kitchen garden. One day, she was digging out radish from the soil. She told Manu that radish is a kind of root. Examine a radish and write what type of root is. What type of venation would you observe in the leaves of radish plant?
Answer: Tap of Root : Tap root
Type of venation : Reticulate.
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: Both are herbivores, belong to the goat species, have hooves, and walk using four legs.
Differences:
Mountain Goat: Has thicker fur/coat to protect against extreme cold and specialized sturdy hooves designed to climb rocky cliffs.
Plain Goat: Has short/thin hair suitable for warmer climates.
Reason for Differences: These differences are adaptations that enable each goat to survive in its specific habitat (cold mountains vs. warm plains).
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: Grouping Criterion: Vertebrates (Animals with a backbone) vs. Invertebrates (Animals without a backbone)
Group 1 (Vertebrates): Cow, Pigeon, Bat, Tortoise, Whale, Fish, Lizard
Group 2 (Invertebrates): 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:The loss of trees and other vegetation due to cutting down of forests can cause climate change, loss of biodiversity, soil erosion, flooding, etc.
We can address this challenge by the following methods
1. Replanting of trees and, putting a ban on cutting of trees.
2. Implementing regulations and laws to address the severity of cutting down the forest.
Answer:
(A) – The plants having leaves with reticulate venation have tap roots.
(B) – The plants not having leaves with reticulate venation have fibrous roots.

NCERT Class 6 Science Chapter 2 Question Answer Diversity in the Living World 3
Answer:
Similarities:
Both are goats and belong to the same family.
Herbivore diet: Both are herbivores. That is they eat plants including roots, stems, leaves etc.
Differences:
Mountain Goat Plains Goat
1. Has thick, long fur to protect against cold mountain temperatures. Has shorter fur suited for warmer climates.
2. Generally stockier and more muscular, adapted for climbing rocky terrains. Leaner build suitable for flat, open areas.
3. Specialised hooves with a rough texture for better grip on rocky surfaces. Hooves more suited for walking on flat, grassy lands.
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:
We can group these animals into two groups based on whether they have backbone or not.
Animals which have backbone Animals which do not have backbone
Cow, pigeon, bat, tortoise, whale, fish, lizard Cockroach, grasshopper
