Detailed explanation-1: -Most seeds need to take up water to germinate; this is known as imbibition GLOSSARY imbibitionthe taking up of liquid, causing swelling. . Water: hydrates enzymes in the seed, activating them. As a result the seed begins to release energy from its food store for growth.
Detailed explanation-2: -This process of the absorption of the water is known as imbibition. Imbibition plays an important role in seed germination. Complete step by step answer: When the seeds are kept in the water, they absorb water by the process of imbibition. Due to this, the seeds get swollen.
Detailed explanation-3: -When soaked in water, the seeds swell up due to imbibition and endosmosis. During these two processes water enters the cell. Due to endosmosis, at some point, the seed coat is unable to bear the turgor pressure and hence, the seed coat bursts.
