a root hair, or absorbent hair, the rhizoid of a vascular plant, is a tubular outgrowth of a trichoblast, a hair-forming cell on the epidermis of a plant root. They are lateral extensions of a single cell and are only rarely branched. They are visible to the naked eye and the light microscope.

Answer 2

Explanation:

Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage. ... The study of root hair biology in Arabidopsis has provided a model cell type for insights into many aspects of plant development and cell biology.
