Xylem cells are found in vascular plants.
Xylem is a type of plant tissue.
Here is how you use xylem in a sentence, "A plant would hardly survive without the xylem tissue. " This is a transportation tissue which is common in vascular plants.
the xylem tubes transport water up and down the stems of plants
A plants vascular structure is made up of xylem and phloem.
Vascular plants have xylem
Water is transported by the xylem.
This is the vascular tissue xylem.
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 .
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 and phloem
1. Centripetal xylem 2. Centrifugal xylem both types are involved in conduction
Xylem cells are in plants not animals.
