Answer 1

Answer:

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.

Explanation:

Plumule is the embryonic shoot of the plant. Radicle is the first part of the seedling. Plumule grows after the radicle. The radicle makes the root of the plant.
