1. Here are two types of seeds. What differences do you find among the roots and leaf venation of their plants?
Ans: (a) Wheat:
Roots – Wheat has fibrous roots. This type of root system consists of many thin, branched roots that spread out from the base of the stem.
Leaf Venation – Wheat leaves exhibit parallel venation. In this pattern, the veins run parallel to each other along the length of the leaf.
(b) Kidney Beans:
Roots – Kidney beans have a taproot system. This consists of one main root that grows vertically downward with smaller side roots branching off from it.
Leaf Venation – Kidney bean leaves exhibit reticulate venation. This pattern forms a network of veins that branch out from a central midrib and spread across the leaf.
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.
Ans: Grouping Animals based on their Habitats Aquatic Animals (Area A):
(i) Dolphin.
(ii) Whale.
Terrestrial Animals (Area B):
(i) Horse.
(ii) Sheep.
(iv) Squirrel.
(v) Pigeon.
(vi) Earthworm.
Animals Living in Both Habitats (Area C):
(i) Frog.
(ii) Crocodile.
(iii) Tortoise.
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 it is. What type of venation would you observe in the leaves of a radish plant?
Ans: A radish is an example of a taproot system, which is characterised by a main root that grows vertically downward and is larger than the other roots. This type of root stores food and nutrients for the plant.
The leaves of a radish plant exhibit reticulate venation. In this type of venation, the veins form a network-like pattern on the leaf, with smaller veins branching off from the main vein.
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?
Ans: Similarities Between a Mountain Goat and a Plain Goat:
(i) They both are Herbivore animals.
(ii) Both have similar body structures with four legs and hooves.
(iii) Both have horns, though their shapes and sizes may differ.
Differences Between a Mountain Goat and a Plain Goat:
| Mountain Goat | Plain Goat |
| (i) Found in mountainous regions. | (i) Lives in plains, grasslands, and human settlements. |
| (ii) Has thick fur to protect against cold mountain temperatures. | (ii) Has short fur to suited for warmer climates. |
| (iii) Shorter and stronger legs for climbing steep slopes. | (iii) Longer and more slender legs for running and walking on plains. |
Reasons for These Differences:
(i) Mountain goats have thick fur and strong hooves to survive in cold and rocky terrains, while plain goats have light fur and softer hooves for warm and flat areas.
(ii) Mountain goats graze on high-altitude vegetation, while plain goats rely on grass and farm crops.
(iii) Mountain goats need thick woolly fur to retain body heat, whereas plain goats require less fur for better cooling.
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.
Ans: These animals based on their habitat-animals that live on land (terrestrial) and animals that live in water (aquatic).
Terrestrial Animals:
(i) Cow.
(ii) Cockroach.
(iii) Pigeon.
(iv) Bat.
(v) Tortoise.
(vi) Grasshopper.
(vi) Lizard.
Aquatic Animals:
(i) Whale.
(ii) Fish.
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?
Ans: Impact of Deforestation:
(i) Cutting down forests destroys habitats, endangering wildlife species.
(ii) Trees help in rainfall and groundwater recharge; deforestation leads to water scarcity.
(iii) Trees absorb carbon dioxide. Cutting them down increases the concentration of greenhouse gases, contributing to global warming.
(iv) Trees help in holding the soil together. Without them, the soil becomes loose and prone to erosion.
Addression the Challenge:
(i) Planting new trees to replace those that have been cut down.
(ii) Ensuring that logging is done in a way that does not harm the ecosystem.
(iii) Teach people about the importance of forests and how to conserve them.
(iv) Use sustainable farming, urban planning, and green technology to reduce deforestation.
7. Analyse the flowchart. What can be examples of ‘A’ and ‘B’?
Ans: Examples of ‘A’
These are plants that have reticulate venation in their leaves.
Examples: Mango, Hibiscus, Rose.
Examples of ‘B’
These are plants that do not have reticulate venation (i.e., they have parallel venation).
Examples: Wheat, Maize, Grass.
8. Raj argues with his friend Sanjay that “Gudhal (hibiscus) plant is a shrub”. What questions can Sanjay ask for clarification?
Ans: Sanjay can ask for clarification:
(i) What are the characteristics of a shrub?
(ii) How tall does a hibiscus plant usually grow?
(iii) Does the hibiscus plant have a strong woody stem like a tree, or is it more bush-like?
(iv) How do the branches of the Gudhal plant appear ?
(v) what is the height of the “Gudhal (hibiscus) plant?
9. Based on the information in the table, find out examples of these plants for each group.
| Group | Type of seed | Type of root | Examples |
| A | Dicot | Taproot | |
| B | Monocot | Fibrous roots |
Ans: Group ‘A’ (Dicot, Taproot)
Example – Mango, Rose, Hibiscus.
Group ‘B’ (Monocot, Fibrous roots)
Example – Wheat, Rice, Maize.
(a) What other similarity do plants of group A have?
Ans: Similarity of Plants in Group A: Plants in Group A (dicots) typically have leaves with reticulate venation.
(b) What other similarity do plants of group B have?
Ans: Similarity of Plants in Group B: Plants in Group B (monocots) generally have leaves with parallel venation.
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?
Ans: Differences in the Feet:
| Duck | Pigeon |
| (i) Duck have webbed feet | (i) Pigeons have regular bird feet with separate toes. |
| (ii) Duck feet are broader and flatter | (ii) Pigeons have sharp claws. |
Activity the Duck Can Perform Using Its Webbed feet:
(i) Swimming – Ducks use their webbed feet like paddles to move smoothly in water.
(ii) Floating and Steering – They adjust their feet to change direction while swimming.
(iii) Walking on Soft Surfaces – The broad feet distribute their weight, preventing them from sinking in muddy areas.
