What is root? List the main functions of root.
Root is that part of a plant which is below the ground (in the soil). The main functions of roots are as follows:

What are herbs, shrubs and trees? Give two examples of each.
- Herbs: Herbs are small plants having a soft and delicate stem. Herbs do not have woody stem. They are non-woody plants. Herbs have a green and tender stem. They are short sized plants. Herbs have short life span. For example, tomato, cabbage.
- Shrubs: Shrubs are medium-sized plants with a hard and woody, branching out near the base. Shrubs tend to branch near ground level, so many branches are seen rising just above the ground giving them a bushy appearance. For example, lemon, tulsi, etc.

- The stem of a plant carries water and minerals from the roots to the leaves and other parts of the plants.
- The stem carries the prepared food from the leaves to other parts of the plant.
- The stem holds the leaves in such a way that the leaves are able to get plenty of sunlight for preparing food by photosynthesis.
What is leaf? What are its functions?
The leaf is a thin, broad, flat and green part of a plant which is attached to the stem (or branch). The leaves of plants have three main functions:
- The leaves make food for the plant by photosynthesis.
- The leaves get rid of excess water from the plant through transpiration.
- The leaves carry out the process of respiration in plants.
Draw a labelled diagram of a flower.
The main parts of a flower are sepals, petals, stamen and pistil.
What is a fruit?

Differentiate between herbs and shrubs.
|1. Herbs are small plants having a soft and delicate stem.||1. Shrubs are medium-sized plants with hard and woody stem.|
|2. Herbs do not grow more than one metre in height.||2. Shrubs tend to branch near ground level.|
|3. They have a very short life span, e.g., tomato, cabbage, etc.||3. They have life span shorter than that of trees but more than herbs, e.g., cotton, tulsi, etc.|
Differentiate between taproot and fibrous root.
|1. Taproot has only one main and long root.||1. Fibrous root do not have a main root.|
|2. Taproot goes deep in the soil.||2. They do not go deep into the soil.|
|3. Taproots are found in plants which have reticulate venation in their leaves.||3. These are found in plants which have parallel venation in their leaves.|

(ii) Pollen grains
Write the name of plant parts which perform the following functions:
(iii) Preparing food
Which part of the flower is necessary for reproduction? Why?
Stamen and pistil are necessary for reproduction as they produce male gamete and female gamete respectively. Petals helps in attracting insects for pollination as they are variously coloured whereas sepals protect the flower buds. Both petals and sepals are accessory parts of the flower.
What is the function of seed coat?
Seed is surrounded by a tough covering called seed coat. It protects the seed from outer harsh environment.
What is the main difference between climbers and creepers?
Climbers need support whereas creepers can grow along the ground. Climbers have tendrils for climbing but creepers do not have this structure.

After learning about types of roots Amrita was too curious to see types of roots in different plants. She started uprooting plants from the garden.

(b) How leaves can determine the type of roots?
(c) What value of Shweta is shown here?
(a) Two types of roots are taproot and fibrous root.
(b) The design made by veins in a leaf is called the leaf venation. The pattern of leaf venation determines the type of roots present in a plant. If the leaf have reticulate venation then it has taproot and if the leaf have parallel venation then it has fibrous root.
(c) Shweta is intelligent, eco-friendly and have scientific aptitude.
