DENDROLOGY

Detailed explanation-1: -The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling.

Detailed explanation-2: -Roots grow downward and are present inside the soil. Shoots are structures that develop upward to form stems, leaves, flowers and buds. Q. Which part of the plant grows below the soil?

Detailed explanation-3: -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. Water is essential for metabolic activity, but so is oxygen. A seed sitting in a glass of water will not survive.

Detailed explanation-4: -The process by which the seed develops into the seedling is called germination. During this process, seedling gets developed into an embryo which gradually develops into a new plant. Q. What are the functions of the following in a seed?
