Detailed explanation-1: -In plant physiology, dormancy is a period of arrested plant growth. It is a survival strategy exhibited by many plant species, which enables them to survive in climates where part of the year is unsuitable for growth, such as winter or dry seasons.

Detailed explanation-2: -dormancy, state of reduced metabolic activity adopted by many organisms under conditions of environmental stress or, often, as in winter, when such stressful conditions are likely to appear.

Detailed explanation-3: -Dormancy is a general term used to describe a period in an organism’s life cycle when metabolic activity is minimized and active development is temporarily suspended. Thus, it helps an organism to conserve energy. Among types of dormancy are hibernation, estivation, diapause, brumation, and torpor.

Detailed explanation-4: -There are two different categories of seed dormancy: exogenous and endogenous (Scarification). Exogenous dormancy is caused by conditions outside of the seed’s embryo. An example of exogenous dormancy is when the seed coat is too durable for moisture to infiltrate, effectively preventing germination.

Detailed explanation-5: -Dormancy is classified into three types based on its mode of action: physical, physiological, and morphological.
