In seed anatomy, which part develops into the root of the new plant?

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

Answer: (B)

During germination, the embryonic root, or radicle, is the part that grows downward to become the plant’s root system. It anchors the seedling and begins absorbing water and nutrients from the soil. The shoot that will rise above ground comes from the plumule, the growing tip of the shoot. The hypocotyl is the segment between the radicle and plumule, often helping push the seedling upward, and the cotyledons store nutrients and typically function as the first seed leaves. So the radicle is the part that develops into the root.
