EVERYDAY SCIENCE

Detailed explanation-1: -The radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic root of the plant, and grows downward in the soil (the shoot emerges from the plumule).

Detailed explanation-2: -germination, the sprouting of a seed, spore, or other reproductive body, usually after a period of dormancy.

Detailed explanation-3: -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 radicle (primary embryonic root) emerges from the seed first to enhance water uptake; it is protected by a root cap produced by the root apical meristem. Water is essential for metabolic activity, but so is oxygen.

Detailed explanation-5: -1) Life Stages Basically, this is the stage in the plant’s growth cycle that is responsible for reproduction of the plant. The germination stage is where the plant grows from the seed. In the right environment (which we’ll discuss below), seeds start to produce the familiar parts including roots, stems, and leaves.
