Explanation:
Difference between xylem and phloem transport:
Xylem transport Phloem transport
1. Xylem tissues include tracheids, vessels, fibres and parenchyma and serve in ascent of sap/water and minerals. 1. Phloem tissues is a composed of four elements namely, sieve tube elements, companion cell, phloem fibres and phloem parenchyma and serve in translocation of organic nutrients.
2. Due to defined source and sink relationship, the movement is unidirectional. 2. The movement is multidirectional as source sink relationship keeps changing.
3. Xylem transport is not influenced by metabolic inhibitors. 3. Phloem transport is inhibited by metabolic inhibitors
Answer:
Xylem transport Phloem transport
1. Xylem tissues include tracheids , 1. Phloem tissues are composed of
vessles, fibres, parenchyma and four elements namely, sieve tube

serve in translocation of organic
nutrients.
2. Due to defined source and sink The movement is multidirectional
relationship, the movement is as source sink relationship keeps
unidirectional. changing.
3.Xylem transport is not Phloem transport is inhibited by
influenced by metabolic inhibitors. metabolic inhibitors.
4.Xylem vessels and tracheids are Sieve tube are main component
main component of transport. of transport which are assisted by
companion cells.
5. Major driving forces are Being active transport, it uses
transpiration pull and diffusion. ATP.
Hope this helps.
