Explain transport of water in plants?
Answers
Answer:
Overall, water is transported in the plant through the combined efforts of individual cells and the conductive tissues of the vascular system. ... It is carried upward through the xylem by transpiration, and then passed into the leaves along another water potential gradient.
Answer:
Plants have two systems for the transportation of substances - using two different types of transport tissue. Xylem transports water and solutes from the roots to the leaves, while phloem transports food from the leaves to the rest of the plant. Transpiration is the process by which water evaporates from the leaves, which results in more water being drawn up from the roots. Plants have adaptations to reduce excessive water loss. Phloem transports synthesized food from the leaves to the rest of the plant body.
Water from the roots is pulled up by this tension. At night, when stomata close and transpiration stops, the water is held in the stem and leaf by the cohesion of water molecules to each other as well as the adhesion of water to the cell walls of the xylem vessels and tracheids.
