Answer

Root hairs developed in the MATURATION region....

Answer

The Root is divided into 3 zones : a zone of cell division , a zone of elongation and a zone of maturation.  The zone of cell division is closest to the root tip & is made up of the actively dividing cells of the root meristem. The zone of elongation is where the newly formed cell increase in length. Beginning at the first Root hair is the zone of cell maturation, where root cells differentiated into specialized cell types.

Answer

Maturation

Answer

Root hairs develop from the region of maturation.
Explanation:
Root hairs are tiny, finger-like extensions that develop from the outer layer of cells in the region of maturation of a plant root. They are specialized structures that greatly increase the surface area of the root for absorption of water and nutrients from the soil. Here is a detailed explanation of each option:
A: Elongation
- Elongation refers to the phase of root growth where cells in the root region increase in length.
- While elongation is an important process in root development, it is not specifically responsible for the formation of root hairs.
B: Root cap
- The root cap is a protective layer of cells located at the tip of the root.
- Its main function is to shield the delicate meristem (the region of actively dividing cells) behind it during root growth.
- Root hairs do not develop from the root cap.
C: Meristematic activity
- Meristematic activity refers to the division of cells in the meristem region.
- This process is responsible for root growth and the production of new cells.
- While meristematic activity is crucial for root development, it does not directly lead to the formation of root hairs.
D: Maturation
- The region of maturation is the area of the root where cells differentiate into specific cell types and acquire their specialized functions.
- Root hairs develop from the outer layer of cells in this region.
- Maturation is the correct answer because it is the specific region where root hairs originate.
In conclusion, root hairs develop from the region of maturation in a plant root.
