NEET BIOLOGY

Detailed explanation-1: -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: -Radicle is the first part of a seedling to emerge from the seed during the process of germination. It is the embryonic root of the plant and grows downward into the soil.

Detailed explanation-4: -When a seed is exposed to the proper conditions, water and oxygen are taken in through the seed coat. The embryo’s cells start to enlarge. Then the seed coat breaks open and a root or radicle emerges first, followed by the shoot or plumule that contains the leaves and stem.

Detailed explanation-5: -Germination-pollination-fertilization-seed dispersal.
