Diversity in the Living World
📝 Chapter Summary — Key Points
- We are surrounded by a large variety of plants and animals. Such variety is a part of biodiversity.
- Plants and animals can be grouped on the basis of similarities and differences among them.
- Plants have similarities and differences based on features associated with roots, stems, leaves, flowers, and seeds.
- Plants can be grouped into herbs (soft green stems), shrubs (multiple woody stems branching near ground), and trees (tall, thick woody trunk) based on their height, types of stem, and branching patterns.
- Plants can also be grouped as dicotyledons (dicots) and monocotyledons (monocots) based on the number of cotyledons in their seeds.
- Monocots generally exhibit parallel venation in their leaves and possess fibrous roots; dicots typically exhibit reticulate venation in their leaves and possess taproots.
- Animals have different types of movement that can be a basis for their grouping.
- Biodiversity of different regions varies because of distinct environmental conditions.
- The special features that enable plants and animals to survive in a particular region are called adaptations.
- The place where plants and animals live is their habitat. Habitats can be terrestrial (land) or aquatic (water).
- Due to damage of their habitats, plants and animals lose their homes, food, and other resources — this results in the loss of biodiversity.
- We must protect biodiversity so that our planet remains full of life, helping plants and animals to survive and thrive.

Q1. Here are two types of seeds. What differences do you find among the roots and leaf venation of their plants? L4 Analyse
Wheat is a monocot plant → it has parallel venation in its leaves and fibrous roots.
Kidney bean (Rajma) is a dicot plant → it has reticulate venation in its leaves and a taproot system.
The key difference lies in the number of cotyledons: wheat seeds have one cotyledon (monocot) while kidney beans have two cotyledons (dicot). This correlates with venation and root type.
Q2. 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'. L4 Analyse
Animals: Horse, Dolphin, Frog, Sheep, Crocodile, Whale, Squirrel, Earthworm, Pigeon, Tortoise
A (Aquatic only): Dolphin, Whale
B (Terrestrial only): Horse, Sheep, Squirrel, Earthworm, Pigeon
C (Both habitats): Frog, Crocodile, Tortoise
Note: Frog is an amphibian (lives in water and on land). Crocodile lives in water and on river banks. Tortoise can live on land and near/in water.
Q3. 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 radish plant? L3 Apply
Q4. 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? L4 Analyse
Differences:
• Mountain goat has thicker, longer fur to keep warm in cold mountain temperatures; plains goat has a thinner coat.
• Mountain goat has sure-footed hooves adapted for climbing rocky, steep slopes; plains goat has hooves better suited for flat ground.
• Mountain goat may be stockier and sturdier to handle harsh weather conditions.
Reason: These differences are adaptations — special features that help each animal survive in its specific habitat. Cold mountains require thick fur and sure-footed hooves, while flat warm plains do not need such adaptations.
Q5. 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. L6 Create
Group 1 (Animals with hair/fur): Cow, Bat, Whale
Group 2 (Animals without hair/fur): Cockroach, Pigeon, Tortoise, Fish, Grasshopper, Lizard
Another possible grouping — by ability to fly:
Can fly: Pigeon, Bat, Cockroach, Grasshopper
Cannot fly: Cow, Tortoise, Whale, Fish, Lizard
Note: Many valid groupings exist. The key is to clearly state the basis (criterion) for your grouping.
Q6. 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? L5 Evaluate
• Loss of habitat for wild animals and birds → decline in biodiversity
• Increase in air pollution (fewer trees to absorb CO₂)
• Soil erosion and floods (tree roots hold soil in place)
• Climate change (trees help regulate temperature)
• Loss of medicinal plants and natural resources
How to address it:
• Plant more trees (afforestation and reforestation)
• Create and enforce protected areas and national parks
• Use alternative, sustainable materials instead of wood
• Promote awareness about the importance of forests
• Support community-based conservation like sacred groves
• Reduce paper waste and recycle
Q7. Analyse the flowchart. What can be examples of 'A' and 'B'? L4 Analyse
A = Dicot plant (has reticulate venation) — Examples: Hibiscus, Peepal, Neem, Rose
B = Monocot plant (does not have reticulate venation; has parallel venation instead) — Examples: Wheat, Rice, Grass, Banana
The flowchart classifies plants based on their leaf venation pattern, which is a reliable way to distinguish monocots from dicots.
Q8. Raj argues with his friend Sanjay that "Gudhal (Hibiscus) plant is a shrub." What questions can Sanjay ask for clarification? L5 Evaluate
1. "Is the stem of the Gudhal plant hard and woody, or soft and green?" (Shrubs have hard woody stems → Yes, hibiscus has a hard stem)
2. "Do multiple stems branch out close to the ground, or is there one main trunk?" (Shrubs branch near ground → Yes, hibiscus branches low)
3. "Is the plant medium-sized — neither as tall as a tree nor as small as a herb?" (Shrubs are medium → Yes)
4. "Does it grow to be as tall as a mango tree?" (Trees grow very tall → No, hibiscus doesn't grow that tall)
Based on these answers, Sanjay can confirm that Raj is correct — Gudhal is indeed a shrub because it has multiple hard, woody stems branching near the ground and is of medium height.
Q9. Based on the information in the table, find out examples of each group. L3 Apply
| Group | Type of Seed | Type of Root | Examples |
|---|---|---|---|
| A | Dicot | Taproot | ? |
| B | Monocot | Fibrous roots | ? |
Group A (Dicot + Taproot): Chickpea (chana), Mustard, Pea, Sunflower, Hibiscus, Neem, Mango
Group B (Monocot + Fibrous roots): Wheat, Rice, Maize (corn), Grass, Banana, Onion
Other similarities within each group:
• Group A plants also have reticulate venation in their leaves
• Group B plants also have parallel venation in their leaves
Q10. 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? L4 Analyse
Difference: The duck has webbed feet — skin between the toes that connects them like a paddle. The pigeon has non-webbed, separated toes with claws for gripping branches and walking on flat surfaces.
Function of webbed feet: Webbed feet act like paddles, helping the duck swim efficiently in water. The web increases the surface area of the foot, pushing more water with each stroke. This is an adaptation for living in and around water.
Why pigeons don't need webbed feet: Pigeons live on land and trees. Their separated toes with claws help them perch on branches and walk on the ground.
- Label the plants in your school with their local names with the help of your teacher or the gardener. List them in your notebook.
- Plan a field visit or nature walk with your teacher. Create a class biodiversity register by consolidating observations and notes from all students.
- Find out about 'Project Tiger' and other similar projects initiated in India to protect our biodiversity. Prepare a presentation for your class.
- Divide your class into groups of six students each. Initiate a discussion on how you can protect biodiversity around you. Prepare a group-wise report.
- Interact with elders in your family or neighbourhood to find out various plants and animals that they see now but were not seen earlier, and vice-versa. Collect pictures of these plants and animals and paste them in a scrapbook.
