Explain how soaking seed in water breaks it's dormancy?

Soaking seeds in water helps to break their dormancy by softening the seed coat and allowing water to penetrate the seed. This process, known as imbibition, triggers biochemical changes within the seed that signal the beginning of germination. The water also helps to activate enzymes within the seed that are necessary for germination to occur. Additionally, soaking seeds in water can help to wash away any inhibitors or chemicals that may be present on the seed coat that could prevent germination. Overall, soaking seeds in water helps to provide the necessary conditions for germination to begin and break the seed's dormancy.

Seed dormancy is a natural state of rest in which seeds are unable to germinate even under favorable conditions. This state is maintained by the presence of inhibitors, which prevent the seed from germinating. Soaking seed in water can break this dormancy by leaching out the inhibitors and allowing the seed to absorb water, which is necessary for germination. The imbibition of water also activates enzymes that help to break down the inhibitors and promote germination. Additionally, soaking seed in water can help to soften the seed coat, which can make it easier for the radicle to emerge.
