Here are the answers for the “Improve Your Learning” section of the lesson “Green World”.

I. Conceptual Understanding

1. Write a brief note on the uses of plants.

• Plants are very useful to us. They provide us with food, oxygen, medicines, timber, and fibres. Roots like carrot and beetroot are eaten as food, while flowers like jasmine and hibiscus are used for decoration and perfumes. Fruits provide us with vitamins and minerals. Plants also help in maintaining the balance of nature.

2. Give examples of land and water plants.

• Land (Terrestrial) Plants: Neem, mango, tamarind.

• Water (Aquatic) Plants: Lotus, water lily, hydrilla.

3. Identify and write some desert plants in your surroundings.

• Cactus, barrel cactus, aloe vera.

II. Questioning and Hypothesis

4. What questions would you like to ask a gardener in your village to know about different types of plants?

• What types of plants grow well in this soil?

• How do you take care of flowering plants?

• What are the benefits of different plants?

• How do you grow seedless fruits?

III. Experiments and Field Observations

5. Go to a nearby garden or nursery. Identify and write the names of as many flowers and plants as you can.

• Flowers: Rose, hibiscus, jasmine, marigold.

• Plants: Tulsi, mint, neem, mango.

IV. Information Skills and Projects

6. Make a chart on the types of plants based on stems and hang it in your classroom.

(This activity involves creating a visual chart showing types of stems like herbaceous, woody, or climbers with examples. Example: Banana – soft stem, Banyan – woody stem.)

V. Drawing and Model Making

7. Make some flowers using colour papers and decorate your classroom.

(This involves crafting flowers like roses or lilies with coloured papers and arranging them in the classroom.)

VI. Appreciation

8. Grow a flowering plant at your home. Record the progress of its growth and discuss with your friends.
