Root Zone for Water and Mineral Absorption
The root zone responsible for water and mineral absorption is the root hair zone, which is located near the root tips. This region is crucial for the uptake of essential nutrients and water from the soil.

Root Hairs
Root hairs are tiny, hair-like extensions that increase the surface area of the roots, allowing for more efficient absorption of water and minerals. These root hairs are in close contact with the soil particles, enhancing the uptake of nutrients.

Epidermis Cells
The epidermis cells of the root hairs have specialized transport proteins that facilitate the movement of water and minerals into the root. These cells play a key role in the selective absorption of nutrients essential for plant growth.

Endodermis
The endodermis is another important layer in the root responsible for regulating the movement of water and minerals into the vascular system of the plant. It contains a band of cells known as the Casparian strip, which forces water and minerals to pass through the plasma membrane of the endodermal cells, ensuring selective absorption.

Xylem and Phloem
Once water and minerals are absorbed by the roots, they are transported through the xylem and phloem tissues to other parts of the plant. The xylem is responsible for transporting water and minerals from the roots to the shoots, while the phloem transports sugars and other organic compounds.
In conclusion, the root hair zone, including root hairs, epidermis cells, and endodermis, is essential for the absorption of water and minerals from the soil. These specialized structures and tissues work together to ensure that plants receive the nutrients they need for optimal growth and development.
