In seed anatomy, which term refers to the part that develops into the root?

• A. Radicle
• B. Plumule
• C. Hypocotyl
• D. Cotyledon

Answer: (A)

In seed anatomy, the part that becomes the root is the radicle. The radicle is the embryonic root that emerges during germination and grows downward to form the plant’s root system, anchoring the seedling and absorbing water and nutrients. The plumule, by contrast, develops into the shoot system—the stem and leaves. The hypocotyl lies between the root and the shoot and helps push the young plant upward, while the cotyledons are the seed leaves that store nutrients for the embryo. So, the radicle is the structure responsible for forming the root.
