NEET BIOLOGY

Detailed explanation-1: -During the beginning stage of germination, the seeds take up water rapidly and this results in swelling and softening of the seed coat at an optimum temperature. This stage is referred to as Imbibition. It starts the growth process by activation of enzymes.

Detailed explanation-2: -Seed germination is the initial step in the life cycle of plants, which begins when the inactive dry seed imbibes water and is completed with the protrusion of the radicle from the seed coat (Nonogaki et al., 2010).

Detailed explanation-3: -The germination process begins when water is absorbed (imbibed) by the seed. This initiates several biochemical events necessary for seedling development.

Detailed explanation-4: -The beginning of the growth of a seed into a seedling is known as germination. All seeds need water, oxygen and the right temperature to germinate.

Detailed explanation-5: -Seed germination is considered to be the initiation of the first developmental phase in the lifecycle of higher plants and is followed by the postgerminative growth of the seedling [1].
