Germination:
Final answer: Germination begins when the seed absorbs water, swells and bursts through the seed coat.
Dry seeds when soaked in water, swells up due to diffusion.
A seed obtains water from the environment, swells and consequently the seed coat ruptures allowing the elongating radicle to come out and form the root system.
