Detailed explanation-1: -The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling. In gymnosperms and dicotyledons (angiosperms with two seed leaves ), the radicle becomes a taproot .
Detailed explanation-2: -Radicle is the first part of a seedling to emerge from the seed during the process of germination. It is the embryonic root of the plant and grows downward into the soil.
Detailed explanation-3: -Roots grow first from the seeds followed by the growth of stem.
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. A seed sitting in a glass of water will not survive.
Detailed explanation-5: -Radicle is the first part of the seedling. Plumule grows after the radicle. The radicle makes the root of the plant.
