Is mature phloem tissue dead upon maturity?
No, they are usually living. It is the xylem tissue that is made mostly of dead cells.
Are phloem cells alive?
Yes, Phloem cells are alive.
What is the effect of dead phloem?
dead phloem causes bark to formon atree
Do xylem and phloem tissues stay alive all the time?
No xylem die at maturity but phloem stays alive all the time the plant is alive.
What are Dead and live tissue of xylem and phloem?
in xylem all the cells R dead IN PHLOEM EXCEPT PHLOEM FIBRES ALL R LIVING CELLS
Does dead phloem makes bark?
No
Are phloem and xylem alive throughout the plant's life?
yes
Do dead phloem make up bark?
Yes they do. The Phloem make up the innermost layer of the bark.
What is dead phloem called on a tree?
Phloem is actually composed of still-living cells that transport sap. Perhaps you are asking about xylem which is composed primarily of dead cells.
How do phloem cells differ from xylem cells in a tree?
There is a layer of living Phloem and there is a layer of living xylem. Both these layer produce dead tissue, the Phloem produces bark (dead protective outer layer), the xylem produces wood (dead supportive inner layer). Both the wood and the bark are dead. It is only the two thin layers of Phloem and Xylem that are alive.
Growth tissue between xylem and phloem that produces additional xylem and phloem cells?
The dark center of a stem or root that is dead
Why would phloem be better than xylem for a tissue cuture experiment?
Yes, phloem is living tissue, xylem tends to be woody and dead.
