Question

Root hair develop from
A. Zone of cell maturation
B. Zone of cell elongation
C Zone of mature cells
D. Zone of cell maturation

Answer 1

Hint: A root hair is a tubular extension of a trichoblast, a hair-forming cell on the epidermis of a plant root, the rhizoid of a vascular plant. Because they are single cell lateral extensions and are rarely branched. Their differing lateral elongation increases the exchange area between the root system of the plant and the soil.

Complete answer:
They are not found only in the elongation zone and in the maturation zone, possibly because as the root elongates and moves through the soil, any root hair that occurs is sheared off.
At the top of the root, or nearest to the plant, the maturation region is located. The root cap is known as the end of the root. In the region of cell division, a plant cell will begin and then travel to the area of elongation. A cell will elongate in this zone and then travel to the zone of maturation. The extended version at the tip of the plant's roots is root hair cells.

Hence, the correct answer is option (A).

Note: Under stressful circumstances, the density and/or length of the root hairs (RHS) that are produced is thought to have a significant influence on the production of the plant. Any effort to enhance the root system of a crop would require a thorough understanding of the RH differentiation processes. Recent progress has been documented in the grasses in uncovering the molecular basis of root epidermis specialization. The purpose of this analysis is to present the current view of the differentiation of RH in grass species.
