The structure in the monocot embryo that develops into the primary root is known as the:
Epicotyl
. Hypocotyl
Radicle
Plumule
The structure in the monocot embryo that develops into the primary root is known as the radicle. The radicle is the embryonic root that emerges from the lower end of the hypocotyl during germination and gives rise to the primary root system of the plant. It is an important structure for anchoring the plant in the soil and for absorbing water and nutrients. The epicotyl, on the other hand, gives rise to the shoot system, including the stem and leaves, while the plumule is a small structure at the tip of the epicotyl that develops into the first true leaves of the plant. The hypocotyl connects the radicle and the cotyledon and is the embryonic stem region.
Option c is the correct answer.
