Question

Transport of water through the xylem is​

Answer 1

Transport of water through the xylem is unidirectional.

• In plants, water transportation occurs through the xylem. Root hairs absorb water from the soil. This water moves upward due to transpiration pull.
• Negative pressure is created in the xylem, pulling the water upwards.
• Water only moves in one direction, which is from roots to shoots.
• Phylum is associated with the transport of food bidirectionally.

Answer 2

Transport of water through the xylem is​ an active process

Explanation:

• They are joined adjacently by perforations, xylem vessels conduct better than tracheids components of the xylem. The transport of water through the xylem is passive and is caused by transpiration pull.
• Because of transpiration, the root pressure is positive, but the shoot pressure is negative. As a result, water flows in line with the pressure gradient.
• Water and dissolved minerals are transported from roots to leaves via xylem tissue, which uses some active transport but largely passive mechanisms. Using active transport and osmosis, phloem tissue transfers dissolved sugars up and down a plant.
