Question

Following is not applicable in terms of plant-water relations, if a seed is soaked in water

• A. Water movement along a concentration gradient.
• B. Increase in seeds volume.
• C. Helps the seedlings to emerge out from soil.
• D. No affinity between adsorbent and liquid.

Hint:

Imbibition requires strong affinity between water and seed surface molecules.

Answer 1

The Correct Option is D

When seeds are soaked in water, water moves along a concentration gradient by imbibition and osmosis, leading to seed swelling and germination. The option about no affinity between adsorbent and liquid contradicts the basic principle of imbibition, which depends on such affinity.
