Unidirectional translocation of mineral ions in higher plants occur in ..​

Answer 1

Unidirectional translocation of mineral ions in higher plants occur in xylem tissues.

• In plants, transportation of fluids and nutrients takes place through the vascular system.
• The vascular system comprises of two types of tubes: the xylem and the phloem tubes.
• The xylem tubes are responsible for transportation of water and mineral ions from the roots to other parts of the plants.
• The phloem tubes are responsible for transporting food from the leaves to all other parts of the plant.
• The flow of mineral ions in xylem tissues is unidirectional as water and mineral ions move in an upward direction through the xylem sap.
• On the other hand, the movement of nutrients through phloem is bi-directional.
