Which process requires more energy from the plant moving water up through the xylem or moving nutrients down through the phloem?

The process by which the water moves upward through the xylem requires more amount of energy

Explanation:

Xylem is usually defined as a vascular tissue that helps in the transportation of water from the lower parts to the higher parts of the plants, i.e. from the roots of the plants to the leaves and stems.

On the other hand, phloem is defined as a vascular tissue that is helpful in the transfer of water from the upper parts to the lower parts of the plants, i.e. from the leaves and stems to the roots.

Since, the movement of water is against gravity and requires a higher amount of energy, as compared to the movement of nutrients downward. So, the process by which the water moves upward through the xylem requires more amount of energy.
