Detailed explanation-1: -An embryo of a seed consists of radicle, plumule and cotyledons .

Detailed explanation-2: -In a seed, the embryo consists of three main parts: the plumule, the radicle, and the hypocotyl.

Detailed explanation-3: -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-4: -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).

Detailed explanation-5: -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.
