I. Conceptual Understanding
1. Write a brief note on the uses of plants.
Answer: Plants are of great use to us in many ways. They release oxygen and take in carbon dioxide, keeping the air clean. Roots like carrot, beetroot and radish are used as food, and fruits give us vitamins, minerals and fibre. Flowers like hibiscus, neem and tulasi are used in making medicines, while rose, jasmine and lavender are used for fragrant oils and perfumes. Plants like soap-nuts and shikakai are used for cleansing hair, and camel grass and lemon grass are used as cooling mats and insect repellents. Plants also give us wood, shade and beauty, and help protect our environment.
2. Give examples of land and water plants.
Answer:
Land (Terrestrial) plants: Banyan, peepal, mango, tamarind, blackberry, pine, oak and cactus.
Water (Aquatic) plants: Duckweed, water hyacinth, water lily, lotus, hydrilla, tape-grass and mangroves.
Land (Terrestrial) plants: Banyan, peepal, mango, tamarind, blackberry, pine, oak and cactus.

3. Identify and write some desert plants in your surroundings.
Answer: Cactus, barrel cactus, golden barrel cactus, Aloe vera and Agave are some desert plants that store water in their thick stems and can survive with very little water.
II. Questioning and Hypothesis
4. What questions would you like to ask a gardener in your village to know about different types of plants?
Sample Answer:
- Which plants grow best in our village soil and climate?
- How often should each plant be watered?
- Which plants need more sunlight and which need shade?
- How do you protect plants from pests and diseases?
- Which season is best for planting new saplings?
III. Experiments and Field Observations
5. Go to a nearby garden or nursery, identify and write the names of as many flowers, plants.
Sample Answer: Flowers — Hibiscus, rose, jasmine, marigold, lily, lotus. Plants — Tulasi, neem, mango, tamarind, cactus, tomato. (Pupils should record the actual names they observe during their visit.)
IV. Information Skills and Projects
6. Make a chart on the types of plants based on stems and hang it in your class room.
Sample Answer: Prepare a chart showing three types of plants based on stems — Herbs (small, soft, green stem, e.g., tomato, tulasi), Shrubs (medium height, woody stem branching from the base, e.g., rose, hibiscus), and Trees (tall, hard woody stem, e.g., mango, banyan). Draw or paste pictures of each under the correct heading.
V. Drawing and Model Making
7. Make some flowers using coloured papers and decorate your class.
Activity — pupils cut and paste coloured paper flowers (petals, sepals, stem) to decorate the classroom, using the hibiscus flower parts learnt in the chapter as a guide.
VI. Appreciation
8. Grow a flowering plant at your home. Record the progress of its growth and discuss with your friends.
Activity — pupils plant a seed or sapling (e.g., hibiscus, marigold or rose), water it regularly, and note down observations such as sprouting, leaf growth, budding and flowering over a few weeks to share with classmates.
