translocation of solutes

Translocation of solutes

Prerequisites:

Knowledge about methods to study the mineral requirements of plants.

Knowledge of essential elements, their roles and mechanism of absorption of mineral elements in plants.

Concept:

By radio-isotopes, it has been proved that inorganic substances move up the plant through xylem. These substances move along with water by transpiration pull.

The rate at which inorganic solutes are translocated through xylem corresponds to the rate of translocation of water. After absorption of minerals by roots, ions are able to reach xylem by two pathways apoplast and symplast pathway.
