Detailed explanation-1: -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-2: -Radicle is defined as the embryonic root of the plant, which develops into the future root of the plant. It is the first part of the embryo to develop into the root system of plants.

Detailed explanation-3: -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-4: -The root that develops directly from the radicle is termed as true root.

Detailed explanation-5: -The mature seed is comprised of three parts: an embryonic root (radicle) and shoot, food reserve tissues or organs (cotyledons, endosperm, or megagametophyte), and a protective structure, the seed coat (testa).
