AThe plumule
BThe epicotyl
CThe radicle
DThe hypocotyl
Answer & Solution
Correct answer: C. The radicle
1. The embryonic axis has three parts, the plumule, the radicle and the hypocotyl.
2. The radicle is the original root that develops from the germinating seed.
3. As it grows downward to form the tap root, lateral roots branch off to all sides in a dicot.
4. The plumule is the shoot, made up of the epicotyl, young leaves and the shoot apical meristem.
