Detailed explanation-1: -Answer: Solution: Only living seeds can germinate which require optimum conditions like moisture, oxygen and temperature.
Detailed explanation-2: -There are three major stages in the germination process. These are the imbibition of water, increased metabolic activity, and swelling of cells. Germination begins with the seed’s imbibition (absorption) of water.
