Question

Transpiration is a process in which plants

• A. receive water from the soil
• B. absorb water vapour from the air
• C. prepare food from the water
• D. release water vapour

Answer 1

The correct option is D

release water vapour

The correct option is D.

Explanation of the correct option:

1. During transpiration, water molecules in plant tissues are drawn from the plant's aerial parts.
2. Plants require just a small fraction of the water they get for growth and development.
3. The remainder is expelled by transpiration.
4. Transpiration assists in the transportation of water and minerals throughout the plant.
5. Transpiration generates a suction force, which aids in the upward transport of water in plants.
6. It keeps osmosis going and the cells stiff.
7. It preserves the turgidity of the cells and aids in cell division.
8. The healthy development of the plants is aided by optimal transpiration.

Explanation of the incorrect options:

Option A:

The plants receive water from the soil through three processes namely osmosis, diffusion, and active transport.

Option B:

The process during which plants absorb water vapor from the air is known as plant foliar uptake.

Option C:

The process during which plants prepare food from the water is known as photosynthesis.

Final Answer: transpiration is a process in which plants release water vapour.
