Basic Science Class 6 Bharati Bhawan Solution Chapter 9 – Part A

1. How are flowering plants classified?

Ans. Flowering plants are grouped into herbs, shrubs, and trees based on their size and type of stem.

2. What is a tap root?

Ans. The main root that grows vertically downward from the base of the stem is called the tap root.

3. What function does a typical leaf perform?

Ans. The main function of a leaf is to prepare food through a chemical process called photosynthesis. During photosynthesis, water and carbon dioxide are converted into glucose.

4. What is a whorl? How many whorls does a flower have?

Ans. Any circular arrangement of leaves, petals, sepals, etc., around a central axis is called a whorl. A flower typically consists of four whorls.

5. What is reticulate venation?

Ans. Thin, elongated structures called veins extend from the petiole and midrib of a leaf. When these veins form a network pattern across the leaf, it is called reticulate venation.

6. Name four roots which store food.

Ans. Carrot, radish, turnip, and sweet potato are examples of roots that store food.

7. Name a plant in which the stem is modified to store food.

Ans. The stem of an onion plant is modified to store food.

8. Why are the leaves of cacti modified into spines?

Ans. In cacti, the leaves are modified into spines to prevent excessive water loss.

9. Name one plant which climbs with the help of leaf tendrils.

Ans. Pea plants climb with the help of leaf tendrils, which are slender structures that wrap around objects for support.

l. What functions do the roots perform?

Ans. The root performs several functions:

(a) It anchors the plant in the soil.

(b) It absorbs water and minerals from the soil.

(c) It helps prevent soil erosion by binding the soil together.

2. Why do the roots of some plants get modified? Mention two functions performed by modified roots with examples.

Ans. Some plant roots are modified to serve additional functions. For example, carrots, radishes, and turnips have swollen tap roots that store food. The stored food is used by the plant when needed. Other roots, such as the prop roots of a banyan tree, provide extra support.

3. What functions does the stem perform?

Ans. The stem has several functions:

(a) It provides support and structure to the plant, keeping it upright.

(b) It bears branches, leaves, flowers, and fruits, distributing them in a way that maximizes their exposure to sunlight.

(c) It transports water, minerals, and food throughout the plant.

4. Distinguish between simple and compound leaves.

Ans. Some leaves, like neem and gulmohar, have divided leaf blades called leaflets. Such leaves are known as compound leaves. On the other hand, a leaf is considered simple when it has a single leaf blade, like those of banyan and peepal trees.

1. Draw a labelled diagram of a leaf. What functions do the veins serve? Name the two types of venation seen in leaves.

1. Figure 9.12 on page 88 illustrates a labeled diagram of a leaf. Thin, elongated structures called veins originate from the petiole and midrib of the leaf. These veins run either parallel to each other (parallel venation) or in various directions (reticulate venation). They provide support to the leaf and transport water, minerals, and food to and from the leaf.

2. Explain the structure of a flower.

2. The stalk of a flower is called the pedicel. The upper swollen part of the pedicel is known as the thalamus. The sepals, which are petal-like structures, emerge from the thalamus and enclose and protect the flower when it is a bud. Colored or white petals grow inside the sepals in a circular arrangement. The stalk-like structures with swollen powdery heads are the stamens, which are the male parts of the flower. The stalk-like portion is called the filament, and the swollen tip is the anther, which contains pollen. The flask-shaped structure at the center of the flower, attached to the stalk with a swollen tip, is called the carpel. One or more carpels form the pistil, which is the female part of the flower. The swollen base is the ovary, the stalk is the style, and the swollen tip is the stigma. Inside the ovary, tiny ovules can be found, which later develop into seeds when fertilized.

3. Differentiate between herbs, shrubs and trees in a tabular form. Give two examples of each.

Ans:

Sl. No.HerbsShrubsTrees
1.Small plants with soft green stemsMedium-sized plants which can grow up to 8 or 9 feet. The stem is hard and woody.Tall perennial plants with a thick, hard, woody stem called trunk.
2.May or May not have branchesThey look bushy because they have many branches, which start from the base of the stem and grow in every direction.Branches arise from the trunk after a certain height.
3.They could be creepers or climbers.They are known as hedge plants.Some trees like date palm and coconut do not have branches.  
4.Examples: Rice, marigoldExamples: China rose, crepe jasmineExamples: Mango, guava
