Question

list out the differences between transportation taking place in xylem and phloem
(3 points)​

Answer 1

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 2

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 ascent in sap/water and             elements, companion cells, phloem

minerals.                                                     fibres and phloem parenchyma and

                                                                     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.
