plz answer this question

Answer 1

Xylem transports sap upwards only whereas phloem transports food in both directions. ... Xylem transports water and nutrients from the roots to all the parts and phloem transports food from the leaves to all parts of the plant. Xylem and phloem are similar because they both transport substances in plants..

Answer 2

Xylem moves water and minerals obtain from the soil to the leaves. It is unidirectional. In the xylem tissue, vessels and tracheids of root, stem and leaves are interconnected to form a continuous system of water conducting channels.
Phloem transports food products which occurs in photosynthesis. It takes place in the seive tubes and is bidirectional.
Both are similar as they help in transportation.
I hope you got it :)
