photosynthesis is the main part of transportation system
The main function of a bark in a woody stem includes an outer protective layer and an inner layer of living phloem which transports food through the stem
Plant tissue concerned mainly with conduction, the specialized tissue of higher plants consisting essentially of phloem and xylem.
There is structural difference between xylem and phloem. This is because their function is also different. Had there been no difference in structure, how these could have performed different function?
The xylem generally transports water throughout the plant (and some nutrients) while the phloem transports soluble organic material made during photosynthesis.
function of xylem vessel is water conduction
Xylem is responsible for conduction of water and minerals and phloem is responsible for conduction of food material in the plants.
In a plant, Phloem tissue carries photosynthesis products (sugars e.g. sucrose) from leaves to roots, growing tissue and fruits. But not minerals (these are carried from the roots to the leaves by the Xylem).
the xylem transports water and the phloem transports organic substances.
Xylem caries water and disolved nutrients from the roots throughout the plant. Phloem carries/ distributes the products of photosynthesis (mainly from the leaves) to the rest of the plants. A good way to remember their function is: Xylem is the upward conduction of water while phloem is the upward and downward conduction of food and minerals.
Xylems and phloems look alike due to their specialized structure and function. Xylem in the vascular plants consists of similar tissues of trachieds, vessels and xylem parenchyma and perform the same function of transportation of water and minerals, hence it looks similar in all such plants. Likewise phloem consists of sieve tubes, companion cells and phloem parenchyma and perform the same function of conduction of food material to different plant parts.
a. conduction of substance b.regulation of opening and closing stomata c. photosynthesis
No, xylem's main function is to carry water up from the roots. Phloem is the tissue which carries the sugar solution.

The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
