What tissue is responsible for forming secondary xylem and phloem in terrestrial perennial plants?
Xylem is part of the vascular tissue of plants, and the xylem and phloem together are grouped together as the stele (latin for 'pillar'). Xylem tissue is encased in lignin, the substance that creates the strength of wood, causing the protoplasm (living part of the cell) to die, and therefore be dead tissue; phloem is living tissue.
What are Dead and live tissue of xylem and phloem?
Dead tissue in xylem includes the vessel elements and tracheids that transport water and minerals, while live tissue includes the xylem parenchyma cells that provide support and store nutrients. In the phloem, the sieve tube elements are living cells responsible for transporting sugars, while companion cells support and aid in nutrient transport.
The woody cells of a tree are formed from dead connective tissues true or false?
False. The woody cells of a tree are primarily formed from living cells called cambium that produce new layers of xylem and phloem, which then become part of the tree's structure as they mature and lignify. Wood cells themselves are actually dead at maturity and provide structural support to the tree.
How does xylem differ from Phloem on?
Xylem and phloem are two types of vascular tissues in plants that serve different functions. Xylem primarily transports water and dissolved minerals from the roots to the rest of the plant, using specialized cells like tracheids and vessel elements. In contrast, phloem is responsible for transporting organic nutrients, particularly sugars produced during photosynthesis, throughout the plant. Additionally, xylem is composed of dead cells at maturity, while phloem consists of living cells.
How do fungus affects the role of both xylem and the phloem?
A fungus role is to break down dead or decaying organisms in the environment, while xylem and phloem are vascular tissues that makes up living cells in plants. With that said the fungus may try to steal its nutrients and affect the specific roles that xylem and phloem operates.

What are dead xylem and phloem cells of a woody plant called?
Dead xylem cells are called "tracheids" or "vessel elements," while dead phloem cells are called "sieve cells" or "sieve tube members."
Growth tissue between xylem and phloem that produces additional xylem and phloem cells?
The dark center of a stem or root that is dead
What are Dead and live tissue of xylem and phloem?
Dead tissue in xylem includes the vessel elements and tracheids that transport water and minerals, while live tissue includes the xylem parenchyma cells that provide support and store nutrients. In the phloem, the sieve tube elements are living cells responsible for transporting sugars, while companion cells support and aid in nutrient transport.
Is Phloem is a pipe made of the cell wall of dead cells?
no, that's xylem
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.
Is mature phloem tissue dead upon maturity?
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
The woody cells of a tree are formed from dead connective tissues true or false?
False. The woody cells of a tree are primarily formed from living cells called cambium that produce new layers of xylem and phloem, which then become part of the tree's structure as they mature and lignify. Wood cells themselves are actually dead at maturity and provide structural support to the tree.

Drawing xylem and phloem?
Xylem tissue is responsible for transporting water and minerals from the roots to the rest of the plant, while phloem tissue transports sugars produced by photosynthesis throughout the plant. Xylem is made up of vessels and tracheids, which are elongated cells that are dead at maturity, while phloem consists of sieve tube elements and companion cells to support sugar transport. Xylem is typically found in the center of the vascular bundle, while phloem is located on the outer side.
How do fungus affects the role of both xylem and the phloem?
A fungus role is to break down dead or decaying organisms in the environment, while xylem and phloem are vascular tissues that makes up living cells in plants. With that said the fungus may try to steal its nutrients and affect the specific roles that xylem and phloem operates.
Why would phloem be better than xylem for a tissue cuture experiment?
Yes, phloem is living tissue, xylem tends to be woody and dead.
