The word "xylem" comes from the Greek word "xylon," which means "wood." Xylem is a type of plant tissue that conducts water and nutrients from the roots to the rest of the plant.
The primary function of the xylem is the transport of water and mineral salts from the root through the vascular bundle.It provides support for the plantIt is long and hollow for provide passage for the water and saltsConsists of lignin and fibres to strengthen the vessels and make them impermeableThe xylem is made up of "dead" cells
In Angiosperms , it is xylem vessels ( proto and meta xylem together ) , Xylem sclerenchyma and xylem parenchyma ; together form Xylem tissue ( That is why xylem is called a compound tissue ). In Gymnosperms , xylem vessels are replaced by Xylem tracheids . All other tings are almost the same .
Xylem is a one way flow
primary xylem is primary in nature & is derived from procambium. But secondary xylem is secondary in nature and derived from fascicular cambium and interfascicular cambium. Primary xylem is differentiated into protoxylem and metaxylem, but secondary xylem has no such differentiation. In primary xylem vessels and tracheids are long and narrow, and vessels don't have tyloses, but in secondary xylem, vessels are blocked by tyloses, and vessels and tracheids are wider and shorter. Xylem fibres are more abundant in secondary xylem , and found in small numbers in primary xylem. Also unlike in primary xylem, secondary xylem has differentiated into sapwood & heartwood.

xylem? xylem?
the origin is where the word came from but the specific origin of the word ballot is latin root word.
XEROX, xylem....
The word "origin" is derived from the French word "origin" and the Latin word "originem," both of which mean, beginning, descent, birth, and rise.
where was the word colonel origin
The Vascular Cambium adds cells on both sides, producing secondary Xylem toward the inside of the stem This is true for most vascular plants except for the order Myrtales that has phloem on both sides of the xylem. The cambium structure is quite different in this order.
The origin of the word data is Latin ....
