Question

plumule and radicle together is known as

Answer 1

 botany, the radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination. The radicle is the embryonic rootof the plant, and grows downward in the soil (the shoot emerges from the plumule). Above the radicle is the embryonic stem or hypocotyl, supporting the cotyledon(s).[1]

It is the embryonic root inside the seed. It is the first thing to emerge from a seed and down into the ground to allow the seed to suck up water and send out its leaves so that it can start photosynthesizing.

The radicle emerges from a seed through the micropyle. Radicles in seedlings are classified into two main types. Those pointing away from the seed coat scar or hilum are 

Answer 2

ANSWER :

In a young seed, the radicle first emerges out during the germination process. Radicle later on forms the root. It starts growing inside the soil. A structure called hypocotyl emerges at the top of the radicle. They have the function to support the cotyledons.

After the growth of radicle, the plumule starts emerging out. It turns into shoot later stages. The plumule is also commonly known as the baby shoot.
