Germination is the process during which seed reserves present in the seed are broken down and the embryo starts to grow.

During germination, the seed absorbs water. Germination is irreversible i.e. once begun; the seed cannot be brought back to dormant state,

Seeds which do not germinate even after provided with all the conditions necessary for germination are called dormant seeds and the phenomenon is termed as dormancy.
