Hey there,

XYLEM-
⇒They transport water and minerals absorbed by roots to leaves.
⇒This process of transport is known as "Ascent of sap".
⇒Xylem contains tracheids, trachae, parenchyma and fibre.
⇒Trachae, parenchyma and fibre is absent in Pteridophyta and Gymniosperms.
⇒All four parts are present in Angiosperms.

==================================================

PHLOEM-
⇒They are responsible for transport of food from leaves to all parts of plants.
⇒This process of transportation is called "translocation".
⇒Turger pressure acts against gravitational pull which allow transfer of food to parts higher than leaves.
⇒Turger pressure was propounded by JC Bose.
⇒Phloem contains seive tube, seive plate, fibre, parenchyma and companion cells.
⇒Seive cell is absent in Pteridophyta and Gymniosperm.
⇒Seive tube is absent in Angiosperms.
