What is the primary root?
The primary root is an organ which forms at the root pole of the plant embryo. Introduction. The root and shoot that develop directly from a plant embryo are considered to be ‘primary’. Thus, in a young seedling, the primary root is that which continues the growth of the embryonic radicle.

What are the four main functions of roots?
The first root that comes from a plant is called the radicle. A root’s four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.
