How are water and minerals transported in plants



4. How are water and minerals transported in plants?
Ans. The vascular tissue Xylem transports water and minerals in plants. Transpiration creates a suction pressure, as a result of which water is forced into the xylem cells of the roots. Then there is a steady movement of water from the root xylem to all the plant parts.

    2. Water and Minerals are transported through xylem in plants.The cells in roots that are in contact with soil activity take up ions,creating a difference in concentration of Ions between the cell SAP of roots and soil water.
      Water moves into the roots to eliminate this difference of concentration forming a steady movement of water in the root xylem.This creates a column of water that is steadily pushed upwards.Loss of water from leaves creates a suction that pulls water from the xylem of the routes to aerial parts.
