Question

What are the differences between the transport of materials in xylem and phloem?

Answer 1

Xylem : a plant's vascular tissue, consists of tracheids, vessels, xylem fibers, and xylem parenchyma.
Phloem : a plant's vascular tissue, is made up of companion cells, sieve tube elements, phloem fibers, and phloem parenchyma.
So, the difference between transport of materials in xylem and phloem is :

Transport of materials in xylem		Transport of materials in phloem
1	Xylem tissue helps in the transport of water and minerals.	1	Phloem tissue helps in the transport of food.
2	Water is transported upwards from roots to all other plant parts.	2	Food is transported in both upward and downward directions.
3	Transport in the xylem occurs with the help of simple physical forces such as transpiration pull.	3	Transport of food in phloem requires energy in the form of ATP.
