1. Which of the following combination of features would you observe in the grass?

(a) Parallel venation and fibrous root

(b) Parallel venation and taproot

(c) Reticulate venation and fibrous root

(d) Reticulate venation and taproot

Ans: The correct answer is option (b) Parallel venation and fibrous root.

Grasses have parallel venation on their leaves. Fibrous roots are like thin fibres that arise in groups from the base of the stem.

(a) Weak stem which cannot stand upright: Creeper

(b) Green tender stem: Shrub

(c) Thick, hard stem with branching near Tree the base

(d) Thick, hard stem with branches high: Herb on the plant 

Ans: The correct answer is option (a) Weak stem which cannot stand upright: Creeper. A plant that has thin, long and weak stems is called a creeper. It cannot stand upright and spreads on the ground. A shrub is of medium size and has thick and hard stems. Herbs are small plants with tender and green stems. And trees are tall plants that have thick and hard stems with branches high on the plant.

(a) Conduction of water.

(b) Photosynthesis.

(c) Formation of branches.

(d) Bears flowers and fruits.

(b) Lamina: green flat part of the leaf

(c) Margin: gives shape to the leaf

(d) Veins: transpiration

Ans: The correct answer is option (d) Veins: Transpiration. The process of transpiration involves the evaporation of water, which is carried out by the stomata of the leaves. The veins function as small tubes that carry water into the leaf.

5. Read the following sentences about photosynthesis:

(i) Sunlight, carbon dioxide, chlorophyll and water are necessary.

(b) (i) and (iii)

(c) (ii) and (iv)

(d) (i) and (iv)

Ans: The correct answer is option (b) (i) and (iii). Photosynthesis is a process carried out by leaves that requires sunshine, carbon dioxide, chlorophyll, and water. Glucose is produced, and oxygen is released.

6. Which of the following terms constitute the female part of the flower?

(a) Sepals, petals, and stamen.

(b) Stigma, style, and ovary.

(c) Ovary, stamen, and stigma.

(d) Ovary, style, and stamen.

Ans: The correct answer is option (b) Stigma, style, and ovary.

Ans: The correct match is

10. Boojho wanted to test the presence of starch in leaves. He performed the following steps.

(1) He took a leaf and boiled it in water,

(2) He placed the leaf in a petri dish and poured some iodine over it. He did not get the expected result. Which step did he miss? Explain.

Ans: Boojho skipped the step where he was supposed to boil the leaf in alcohol to eliminate the green colour of chlorophyll, which was required since chlorophyll interferes with the starch test.

11. Will a leaf taken from a potted plant kept in a dark room for a few days turn blue-black when tested for starch? Give reasons for your answer.

Ans: To synthesize starch, the leaf should have gone under photosynthesis. The potted leaf did not undergo the same; there was no process of fresh starch food.

12. Can the stem of a plant be compared with a street with two–way traffic? Give a reason.

Ans: A plant's stem can be compared to two-way traffic. Because in the stem there are two types of tubes, one carries water and minerals from roots to the leaves and other parts. And the other tubes carry food from leaves to other parts of the plant, and roots.

16. Observe the picture of an activity given as Fig. 7.4 carried out with leaves of plants and polythene bags.

(a) Which process is demonstrated in the activity?

Ans: Transpiration

(b) When will this activity show better results – on a bright sunny day or a cloudy day?

Ans: The rate of transpiration depends on sunlight. The more sunlight, the more is transpiration. So it will show better results on a sunny day.

ii) The bag should be dry.

iii) The leaves or the twig should be fresh.

17. Identify the wrong statements and correct them.

(a) Anther is a part of the pistil.

Ans: The given statement is wrong. The anther is not the part of the pistil but the stamen.

(b) The visible parts of a bud are the petals.

Ans: The given statement is wrong. Petals are the flowers of flowers. The visible parts of bud are sepals.

(c) Lateral roots are present in a taproot.

Ans: The given statement is correct.

(d) Leaves perform the function of transpiration only.

Ans: The given statement is wrong. Leaves not only perform the function of transpiration but also perform the functions of photosynthesis, gaseous exchange through tiny pores in them known as stomata.
