(B) The seeds contain hydrophilic substances like starch and proteins that absorb water through the process of imbibition.As water enters the seed, it causes the seed to swell, resulting in the development of a significant force known as imbibition pressure.This pressure is crucial for the germination process as it helps the seed coat rupture and allows the seedling to emerge from the soil.
