Exercise
1. Match the pairs:
Answer –
(a) Amphibian → (3) A Frog
(b) Vertebrate → (1) A Monkey
(c) With scales → (2) A Snake
2. Who is the odd one out?
Answer –
(a) Chrysanthemum (It is a flowering plant, while the others are fungi or algae).
(b) Chickpea (It is a small plant, while the others are trees).
(c) Hibiscus (It is a flowering plant, while the others are fruits).
(d) Banyan (It is a tree, while the others are crops).
(e) Guava (It is a fruit, while the others are root vegetables).
(f) Worms (They are invertebrates, while the others are vertebrates).
3. What is the difference?
(a) Flowering plants vs. Non-flowering plants:
Answer – Flowering plants produce flowers (e.g., Rose, Mango).
Non-flowering plants do not produce flowers (e.g., Fern, Algae).
(b) Tree vs. Shrub:
Answer – Trees are tall with a strong trunk (e.g., Banyan, Mango).
Shrubs are shorter with multiple branches near the ground (e.g., Rose, Hibiscus).
(c) Vertebrates vs. Invertebrates:
Answer – Vertebrates have a backbone (e.g., Fish, Birds).
Invertebrates do not have a backbone (e.g., Snail, Earthworm).
4. True or False?
(a) The snail is an aquatic animal. False (It can be found on land too).
(b) Amphibians can live in air and water. True
(c) The function of the brain is well developed in vertebrate animals. True
(d) The amoeba is a multicellular animal. False (It is a unicellular organism).
5. Write two names of each:
Answer –
(a) Flowering plant: Rose, Sunflower
(b) Non-flowering plant: Fern, Algae
(c) Tree: Mango, Banyan
(d) Shrub: Hibiscus, Rose
(e) Creeper: Pumpkin, Watermelon
(f) Annual plant: Wheat, Sunflower
(g) Biennial Plant – Carrot, Onion

6. Write answers to the following:
(a) What are the parts of a plant?
Answer –The main parts of a plant are roots, stem, leaves, flowers, and fruits.
(b) What are the functions of the root?
Answer –Roots absorb water and nutrients, anchor the plant, and sometimes store food.
(c) Why is it necessary to classify living things?
Answer –Classification helps in studying, identifying, and understanding different living things easily.
(d) What are the criteria used to classify living things?
Answer –They are classified based on structure, body parts, reproduction, and habitat.
(e) Tell some characteristics of creepers.
Answer –Creepers have weak stems, spread on the ground, and need support to grow (e.g., Pumpkin).
(f) Explain the characteristics of herbs with two examples.
Answer –Herbs are small, soft-stemmed plants that live for a short time (e.g., Mint, Basil).
(g) On the basis of which criteria will you classify plants and animals?
Answer –Plants: Based on height, structure, and habitat.
Animals: Based on body structure, backbone presence, reproduction, and habitat.
(h) What protects the bodies of animals?
