Hint: It is the first part of the seedling and it is also the embryonic root of the plant which grows downward in the soil.
Complete answer:
The root of the baby plant just emerging from a seed is called Radicle.
A radicle is a primary root and it is the very first organ of the plant body which appears when a seed germinates.
Radicle is the lower part of the seedling that grows downward in the soil. The hypophysis gives rise to the first root of the seedling i.e. Radicle.
In gymnosperms and angiosperms with 2 seed leaves, the radicle becomes the taproot. The color of the radicle is whitish.
The main function of radicals is that it absorbs water and other important minerals from the soil which helps the plant to grow.
Plumule is the embryonic shoot of the plant which grows upward into air and it produces food by the process called photosynthetic. It is also less whitish in color. So, this option can’t be correct.
Seed coat acts as an outer protective covering for seeds which protects seeds from the damage like temperature change, microorganism’s invasion etc. and seed coat also called Testa. Endocarp also plays the same role as that of seed coat and it is the innermost part of the pericarp.
Thus, the correct answer is option B. i.e., Radicle
Note: The radicle grows in length and moves out of the seed called micropyle. Micropyle when soaked in water, seeds absorb water mainly through micropyle and makes it available to the germination of the embryo.
