Plants absorb water using their roots from the soil. Which part of plant root has the highest water potential?*1 pointEndodermisEpidermisSieve tubeXylem vessel

The part of the plant root that has the highest water potential is the Xylem vessel.

Here's a step-by-step explanation:

1. Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. It determines the direction of water movement.

2. In plants, water moves from areas of high water potential (less negative) to areas of low water potential (more negative).

3. The roots absorb water from the soil, which then moves through different parts of the root like the epidermis, cortex, endodermis, and finally into the xylem vessels.

4. The xylem vessels, which are part of the plant's vascular system, transport this water from the roots to the rest of the plant.

5. Therefore, the xylem vessels have the highest water potential as they are the site of water entry into the plant's transport system.
