Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the question.
The question asks about the region of the root where the tubular, colorless prolongations of epidermal cells are found. These structures are known as root hairs.
Step 2: Analyzing the options.
(A) Cell division: The region of cell division is where cells actively divide to form new cells but does not feature root hairs.
(B) Absorption: Correct — Root hairs are found in the region of absorption, where they increase the surface area for water and mineral uptake.
(C) Maturation: In the maturation region, cells mature and differentiate, but root hairs are mostly absent.
(D) Cell elongation: In this region, cells elongate, but root hairs are mainly present in the absorption zone.
Step 3: Conclusion.
The correct answer is (B) Absorption, as root hairs, which are tubular, colorless projections, are primarily found in this region.
