Question

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

Answer 1

Xylem

Xylem is a vascular tissue found in plants composed of tracheids, vessels, xylem fibers, and xylem parenchyma.

Phloem

Phloem is a vascular tissue found in plants comprising companion cells, sieve tube elements, phloem fibers, and phloem parenchyma.



Transport of material in Xylem	Transport of material in phloem
1. The xylem supplies water from the roots to the stem and leaves.	1. Phloem transports food resources from leaves to other plant portions.
2. Water is transported from ascending roots to aerial parts of the plants.	2. The movement of food in phloem is bidirectional.
3. Physical forces such as transpiration pull are required for transport in the xylem.	3. The transport of food through the phloem requires ATP (Adenosine triphosphate) energy.
