Q.6. Write answers to the following.
a.What are the parts of a plant?
Answer : The parts of a plant are: root, stem, leaves, flowers, fruit and seed.
What are the functions of root?
The functions of root are:
- The root hold the soil firmly and anchor the plant.
- They absorb water, salt and minerals from the soil and transport it to stem.
- Some roots store food. e.g. Carrot, radish.
Why is it necessary to classify living things?
- There is a great diversity in living things- both plants and animals on the earth.
- In order to identify them and to study their characteristics, systematic classification is necessary.
What are the criteria used to classify living things?
Following are the criteria used to classify living things:
- Mode of nutrition.
- Similarities and differences in structure.
- Presence of flowers or not.
- Period of life cycles.
- Cell structure.
- Presence of vertebral column.
- Method of reproduction.
Tell some characteristics of creepers.
The characteristics of creepers are:
- The stem of a creeper is very flexible, soft and green and need support to climb.
- Some climbers spread on the ground, e.g. Pumpkin
- Some have aerial roots, e.g. Money plant
- Some climbers develop tendrils, e.g. Cucumber
Explain the characteristics of herbs with examples.
- Herbs grow 1 to 1.5 m tall.
- Their stem is green and quite flexible.
- They may live for a few months or upto two years, e.g. Tulsi, oregano, etc.
Q. g.How is the body of animals protected?
Answer : Body of animals are protected by special covering such as skins, feathers, scales, hair fur, etc.
Q. h. On the basis of which criteria will you classify plants and animals?
7. Draw figures.
a. Draw the figure of a plant to show the parts, namely, the root, stem and leaves in it.
Q.1. Visit a plant nursery and classify the plants there.
Q. 2.Visit a zoo and obtain information about the diversity in animals.
Q. 3.Write an essay on diversity in plants.
Q. 4.Collect seeds of various plants during summer and throw them in open spaces (fallow land, moorland, hill, etc.) during the rainy season.
