Question

Explain the mechanism by which the water is transported in plants?

Answer 1

1. Xylem moves water and minerals obtained from the soil through roots to all other parts of the plant in a unidirectional manner. Transpiration takes place from the leaf, which causes a transpirational pull in the tracheids and vessels of xylem, facilitating upward movement of water.
2. Roots actively uptake ions from the soil, leading to a difference in the concentration gradient; thereby, water moves into the roots to eliminate this difference, creating a steady movement of water into root xylem.
