Question

Which of the following seeds develops a greater imbibition pressure?

• A. Wheat seed
• B. Gram seed
• C. Rice seed
• D. Mustard oil seed

Answer 1

The correct option is B Gram seed

Imbibition is the first process during seed germination. It is the adsorption of water by the solid and dry surface. All biomolecules imbibe water but to different extent. Proteins imbibe maximum water and fats least. Hence, protein rich gram seeds will develop maximum imbibition pressure and fat rich mustard seeds the least. This is because fats are hydrophobic. Thus, the correct answer is option B.
