The two components of transport in highly organised plants are xylem and phloem.
(i) Xylem tissue is made of dead cells in the form of xylem vessels and tracheids. It tranports water and dissolved minerals from roots to all the parts of the plant.
(ii) Phloem tissue is made of living cells in the form of sieve tubes and companion cells. It transports food made in leaves by photosynthesis to all the parts of a plant.
