DENDROLOGY

Detailed explanation-1: -There is a period of inactivity in the seed, during which the embryo puts its development on hold to attain physical maturation. This period of inactivity is called dormancy. When placed under proper conditions, like water, suitable temperature and air rich in oxygen, the dormant seed starts to germinate.

Detailed explanation-2: -Torpor is a similar term to dormancy, meaning inactivity or lethargy. Dormancy or torpor can involve very different physiological states, in response to a variety of different stimuli, including low temperature, high temperature, lack of water, or lack of food.
