Question

In seed germination, the first phenomenon to take place is

• A. Osmosis
• B. Active transport
• C. Absortion
• D. Imbibition

Answer 1

The correct option is D Imbibition

Imbibition is the first phenomenon in seed germination. Imbibition is a passive physical process and is actually adsorption of water by the dry surface. It causes swelling of dry seeds. Water is the medium for all the metabolic reactions in the living system. Hence, the most important requirement of seed germination is water. Dry seeds adsorb water which marks the beginning of seed germination.

So, the correct answer is 'Imbibition'
