Question

When dried seeds are placed in water they absorb water and swell this because of

• A. Inhibition
• B. Adsorbtion of water
• C. Both
• D. Absorption of water

Answer 1

The correct option is C Both

The substances like cellulose and proteins have great affinity for water i.e., they are hydrophilic this property is called inhibition. When dried seeds are placed in water they absorb water and swell similarly. If dried fruits or raisins are placed in water they imbibe water. You might have noticed that during rainy season wooden doors also absorb some moisture and it becomes difficult to close the doors many components of cells like starch and cellulose attract water. When seed coats get ruptured and process of germination of seed takes place.

So, the correct answer is 'Both'.
