NEET BIOLOGY

Detailed explanation-1: -The correct option is A. Radicle . 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 root of the plant, and grows downward in the soil (the shoot emerges from the plumule).

Detailed explanation-2: -The radicle (primary embryonic root) emerges from the seed first to enhance water uptake; it is protected by a root cap produced by the root apical meristem.

Detailed explanation-3: -Embryo of a seed has two parts, namely plumule and radicle. Plumule gives rise to shoot and Radicle gives rise to root of plant.

Detailed explanation-4: -Plumules: It is part of the seed embryo, which develops into the shoot after seed germination. Also called a baby plant or new plant arising from the seed embryo.

Detailed explanation-5: -Complete answer: Plumule is another word for young shoot and it is said to be negatively geotropic as it moves away from soil, its extension rises from hypocotyls, when hypocotyls grows, the cotyledons are grown out of the soil, but, when epicotyls grows, the cotyledons still remains in the soil.
