Both xylem and phloem are vascular tissues found in a plant. Xylem is a tubular structure which is responsible for water transport from the roots towards all of the parts of the plant. Phloem is also a tubular structure but is responsible for the transportation of food and other nutrients needed by plant. Xylem imports water and minerals while Phloem transports water and food. Xylem exists as non-living tissue at maturity, but phloem is living cells.

Xylem: Hard wall cells transport water and mineral nutrients
Phloem: Relatively soft -walled cells transport organic nutrients

"Hardness and softness" is a function of the amount of lignification and extractive content of the individual cell walls not there location in the tree.

Xylem:
  1. It is a dead complex permanent tissue. Sapwood is xylem and mostly alive
  2. It is the principal water conducting tissue of vascular plants.
  3. Xylem consists of tracheids , vessels , xylem parenchyma and xylem fibres. Also ray parenchyma Also the xylem of softwoods (Gymnospermae) do NOT contain vessels.




Phloem:
  1. It is a living complex permanent tissue. Inner phloem is alive. Outer phloem is dead.
  2. It is the principal food conducting tissue found in vascular plants. Actually only the first .2-.7mm of the phloem is functional in food transport. The rest is non-functioning (ref. Esau's Plant Anatomy, 3rd ed. 2006, Chap.14) also (ALFIERI, F. J., and R. F. EVERT. 1968. Seasonal development of the secondary phloem in Pinus. Am. J. Bot. 55, 518-528.)
  3. It consists of sieve cells , sieve tube elements , phloem parenchyma and phloem fibres. There are also phloem ray cells.

Xylem consists of the inner heartwood (the dead part) and the outer portion called the sapwood (the mostly living part.) Xylem "wood" from the Greek xylon. The actual transport of the water and minerals from the roots (sap) is carried out by the outer portion of the sapwood (nearest the bark).The largest percentage of the sap is transported in the first few growth rings.

Difference between xylem and phloem tissue?

xylem have hard wall cell. it is a dead complex permanent tissue. it is a water conducting tissue. PHLOEM; Phloem have relatively soft wall cell. it is a live complex permanen

How is phloem different from xylem?

The basic function of Xylem is to transport water (and some soluble  minerals) up from the roots and through the plant. Phloem  transports organic nutrients - particularly s

How do xylem and phloem tissues differ?

Xylem is deeper inside the plant (near the trunk) and transports  water up to the leaves. Phloem is near the outside and transports  sugar and other materials all throughout

How does phloem differ from xylem?

How does xylem differ from phloem?

Xylem has a one-way flow . Xylem is found in the roots. It's answered with details on this site http://www.diffen.com/difference/Phloem_vs_Xylem and there's many more e

What is the difference in between xylem and phloem?

The difference between xylem and phloem is functional as well as structural. 1. xylem is used for conduction of water and minerals whereas phloem is used for conduction of pr
