The embryonic shoot that develops into the plant’s above-ground parts is called the?

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

Answer: (A)

In seeds, the embryo has specialized parts that become different parts of the plant. The embryonic shoot that will grow into the above-ground portions—stems and leaves—is the plumule. The plumule contains the shoot apical region that, once germination starts, develops into the stem and first leaves, forming the plant’s above-ground structure. The radicle, by contrast, becomes the root system, anchoring the plant and absorbing water and nutrients. The cotyledons are seed leaves that often store nutrients to power the early growth, and the hypocotyl is the segment that connects the roots to the cotyledons and helps push the shoot upward during germination. So the term that names the embryonic shoot destined for the above-ground parts is plumule.
