Question

The tubular, colourless delicate prolongations of epidermal cells are seen in which region of root in plants?

• A. Cell division
• B. Absorption
• C. Maturation
• D. Cell elongation

Hint:

Root hairs are essential for water and nutrient absorption in plants and are located in the region of absorption in the root.

Answer 1

The Correct Option is B

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.
