Answer

To solve the question regarding the correct sequence of the pathway of water through the root tissues, we will break down the process step by step.

### Step-by-Step Solution:

1. **Entry through Root Hairs (Epidermis)**:
- Water first enters the root through the root hairs, which are extensions of the epidermal cells. This is the initial point of water absorption.

2. **Movement to the Cortex**:
- After entering through the root hairs, water moves into the cortex. The cortex is a thick layer of cells that serves as a storage area and a pathway for water movement.

3. **Reaching the Endodermis**:
- From the cortex, water then travels to the endodermis. The endodermis is the innermost layer of the cortex and contains the Casparian strip, which regulates the flow of water and minerals into the vascular system.

4. **Passing through the Pericycle**:
- After the endodermis, water moves into the pericycle, which is the layer just inside the endodermis. The pericycle is involved in the formation of lateral roots and also plays a role in the transport of water and nutrients.

5. **Finally Entering the Xylem**:
- The last step is where water enters the xylem vessels. The xylem is responsible for transporting water and dissolved minerals from the roots to the rest of the plant.

### Correct Sequence:
The correct sequence of the pathway of water through the root tissues is:
1. Epidermis (Root Hairs)
2. Cortex
3. Endodermis
4. Pericycle
5. Xylem
