Webb1. Transport of molecules in phloem can be bidirectional. 2. The movement of minerals in the xylem is unidirectional. 3. Unloading of sucrose at the sink does not involve the utilization of ATP. 4. Elements most easily mobilized in plants from one region to another are phosphorus, sulfur, nitrogen, and potassium. WebbPhloem tissue is composed of the sieve elements, companion cells or albuminous cells, phloem parenchyma and phloem fibres. Of them, the sieve elements and companion cells are important for transport. The sieve elements are anucleated, elongated living cells, through which transport actually takes place. They are connected end to end with porous …
