The radicle is best described as

• A. The shoot that emerges above ground
• B. The seed's protective coat
• C. The embryonic root that emerges first
• D. The seed's energy storage organ

Answer: (C)

In germination, the first structure to appear from the seed is the radicle, which becomes the embryonic root. This root anchors the seedling and starts taking up water and nutrients, laying down the foundation of the plant’s root system. The shoot that will later rise above the soil comes from the plumule and emerges after the radicle, so it’s not the radicle. The seed’s protective coating stays around the seed as a coat, not the root. The stored food in the seed—within cotyledons or the endosperm—provides energy to the developing embryo but is not the root. Therefore, describing the radicle as the embryonic root that emerges first best matches its role and timing.
