I hope this might help you ☺
Explanation:
Transportation of materials in xylem Transportation of materials in phloem
Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food.
The transportation of water is from upwards roots to aerial parts of plants. Food is transported in both upward and downward directions.
Transport in the xylem requires physical forces such as transpiration pull. Transport of food
phloem requires energy in the form of ATP.
Metabolic inhibitors do not influence xylem transport. Metabolic inhibitors inhibit phloem transport.
Xylem tissues include tracheids, vessels, fibres and parenchyma and serve in the ascent of sap/water and minerals. Phloem tissues are composed of four elements: sieve tube elements, companion cell, phloem fibres, and phloem parenchyma and serve in the translocation of organic nutrients.
