Detailed explanation-1: -A tiny pore called micropyle is located close to the hilum. It is this pore through which the germinating seed absorbs water and also serves as a place for diffusion of respiratory gases.

Detailed explanation-2: -The Process of Seed Germination 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.
