Detailed explanation-1: -Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores. Like all organisms, this is done through a process known as aerobic respiration.-a series of reactions where energy is released from glucose, using oxygen.
Detailed explanation-2: -Seeds germinate in the presence of suitable conditions. On absorbing adequate water, the seed swells up, leading to the seed coat’s bursting. It gives rise to a baby plant called seedling. The embryo receives nourishment from the cotyledon till the root system is developed.
Detailed explanation-3: -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.
Detailed explanation-4: -The endosperm contains the starch or stored energy for the developing embryo. The endosperm is the largest part of the seed and packed around the embryo.
