Sample questions
-
1.Plants have no blood, yet we sometimes say that a plant is "bleeding". How do you justify this statement?
- A.Plants lose sap from cut surfaces due to root pressure, resembling bleeding in animals.
- B.Plants contain a red fluid similar to blood that flows out when injured.
- C.Bleeding in plants occurs because they have a circulatory system like animals.
- D.The term "bleeding" is used metaphorically but has no scientific basis in plants.
-
2.(i) Transpiration and guttation (form of water) (ii) Lenticels and stomata in old plants (gases given out during day time).
-
3.Why is the rate of transpiration higher on a windy day compared to a calm day?
- A.Wind increases the temperature around the leaves, speeding up transpiration.
- B.Wind removes water vapor from around the leaves, increasing the diffusion gradient.
- C.Wind forces more water out of the stomata by physical pressure.
- D.Wind enhances the absorption of water by the roots, increasing transpiration.
-
4.If a plant is kept covered with a polythene sheet we notice some water drops on the inner side of the sheet after sometime. This is due to .................
- A.Evaporation
- B.Transpiration
- C.Transportation
- D.Translocation
-
5.How would you justify the statement that transpiration contributes in bringing rain?
- A.Transpiration releases water vapor from plants, increasing atmospheric moisture, which condenses to form clouds and leads to rainfall.
- B.Transpiration cools plant leaves, which lowers the temperature of the surrounding air and causes rain.
- C.Transpiration absorbs water from the soil, reducing groundwater levels and forcing rain to replenish it.
- D.Transpiration produces oxygen, which reacts with atmospheric gases to form rainwater.
