Current Question (ID: 12471)

Question:

Root hairs are __________ and formed from _________ zone of root.

Options:

1. unicellular, maturation
2. multicellular, elongation
3. multicellular, maturation
4. unicellular, elongation

Solution:

Root hairs are unicellular structures that are formed from the maturation zone of a root. Root hairs are thin, elongated, tubular outgrowths of epidermal cells on the surface of a root, and they greatly increase the surface area of the root for absorption of water and nutrients from the soil. Root hairs are formed as a result of the elongation and differentiation of cells in the maturation zone of the root, which is located behind the root cap and is responsible for the growth and development of root cells as they mature into specialized cell types with specific functions, such as root hairs for absorption.
