📘 Lesson 2: Diversity in the Living World — Answers

Class 6 Science — Let us enhance our learning (Textbook Exercise Answers)

Question 1

Which combination of features is correctly matched with a dicot plant?

Answer: (b) Reticulate venation – Tap root – Two cotyledons ✅

Question 2

Group the animals based on their habitat (Horse, Dolphin, Frog, Sheep, Crocodile, Squirrel, Whale, Earthworm, Pigeon, Tortoise):

A (Aquatic): Dolphin, Whale
B (Terrestrial): Horse, Sheep, Squirrel, Pigeon
C (Both - Aquatic & Terrestrial): Frog, Crocodile, Earthworm, Tortoise

Question 3

Classify rose, mango, wheat, coconut based on stem type and branching pattern:

Shrub: Rose (branches close to ground, hard thin stem)
Tree: Mango (tall, hard thick stem, branches higher up)
Herb: Wheat (short, soft green stem)
Tree without branches: Coconut

Question 4

Find examples for Group A (Dicot, Taproot) and Group B (Monocot, Fibrous root):

Group A examples: Mango, Hibiscus, Chickpea, Rose
Group B examples: Wheat, Maize, Grass, Lemongrass

(a) Similarities in Group A: They have reticulate (net-like) venation in leaves and two cotyledons in their seeds.
(b) Similarities in Group B: They have parallel venation in leaves and one cotyledon in their seeds.

Question 5

Mountain goat vs. goat found in plains — similarities and differences:

Similarities: Both are goats, have four legs, horns, and eat grass.
Differences: The mountain goat has thicker, longer fur to keep it warm in the cold mountains. The plains goat has short, thin fur since it lives in a warmer place.
Reason: These are adaptations that help each goat survive in its own habitat (cold mountains vs. warm plains).

Question 6

Differences between wheat seeds and kidney bean seeds (roots and leaf venation):

Wheat: Monocot seed (one cotyledon) → fibrous roots → parallel venation
Kidney beans: Dicot seed (two cotyledons) → taproot → reticulate venation

Question 7

Radish plant — type of root and venation:

Answer: Radish has a taproot (the swollen radish we eat is the main root). Its leaves show reticulate (net-like) venation.

Question 8

Flowchart — examples for A and B:

A (leaves + reticulate venation): Hibiscus, Mango, Rose
B (leaves but no reticulate/parallel venation instead): Wheat, Maize, Grass

Question 9 Diversity in the Living World

Duck's feet compared to pigeon's feet:

Answer: The duck has webbed feet (skin joining the toes), while the pigeon does not. Webbed feet help the duck to paddle and swim easily in water.

Question 10

Assertion-Reason: Plants with reticulate venation have taproots; reason - they have two cotyledons.

Answer: (a) Both A and R are true, and R is the correct explanation of A ✅

Question 11

A plant with parallel venation and fibrous roots was placed in dicots. Is this correct?

Answer: This is not correct. Parallel venation and fibrous roots are features of monocot plants, not dicots. So this plant should be placed in the monocot group.

Question 12

Effect of cutting down forests due to population growth, and how to address it:

Effect: Cutting forests destroys the homes of plants and animals, reduces biodiversity, causes soil erosion, and affects rainfall and air quality.
Solution: We can plant more trees, protect forests, use paper and wood carefully, and support wildlife sanctuaries and national parks.

Question 13

Raj says "udhal (hibiscus) plant is a shrub." What can Sanjay ask for clarification?

Sanjay can ask:
1. Is the stem hard/woody and does it branch close to the ground?
2. Is the plant medium in height (not as tall as a tree)?
3. Does it have many woody stems instead of one thick stem?

Question 14

Group the animals into two groups based on any feature other than those discussed (cow, cockroach, pigeon, bat, tortoise, whale, fish, grasshopper, lizard):

Based on number of legs:
Group 1 (4 legs): Cow, Tortoise, Lizard
Group 2 (6 legs / no legs / other): Cockroach, Pigeon, Bat, Whale, Fish, Grasshopper

(Students may also group by egg-laying vs. giving birth to young ones, or by presence/absence of wings — cow, tortoise, whale, fish, lizard do not fly; cockroach, pigeon, bat, grasshopper can fly.)

✅ Tip for students: Always relate your answers to what you observed in the nature walk activities — plants, animals, roots, leaves, and habitats!
