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.

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.
Do dead phloem make up bark?
Yes, dead phloem cells contribute to the outer protective layer of a tree known as bark. The outermost layer of bark is primarily composed of dead cells, including dead phloem tissue, that provide protection from environmental factors and pathogens.
What is dead phloem called on a tree?
Dead phloem on a tree is called "inner bark" or "bast." It serves to transport nutrients within the tree but is no longer living tissue once it dies.
How do phloem cells differ from xylem cells in a tree?
Phloem cells transport organic nutrients like sugars from leaves to other parts of the plant, while xylem cells transport water and minerals from roots to other plant tissues. Phloem cells are alive at maturity and contain sieve tubes for nutrient transport, while xylem cells are dead at maturity and contain tracheids or vessel elements for water transport.
What does the phloem do?
Phloem - a protective layer made up of tiny tubes that transport the sugars from the leaves to the rest of the tree.Xylem - the main part of the tree trunk made up of tiny tubes which transport water and minerals from the roots up the trunk and branches to the leaves.phloem carries organic nutrients to all parts of the plant where required.Its mainly concerned with transport of soluble organic material.
Why would phloem be better than xylem for a tissue cuture experiment?
Yes, phloem is living tissue, xylem tends to be woody and dead.

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.
Do dead phloem make up bark?
Yes, dead phloem cells contribute to the outer protective layer of a tree known as bark. The outermost layer of bark is primarily composed of dead cells, including dead phloem tissue, that provide protection from environmental factors and pathogens.
Are there visible nuclei in the sclerenchyma tissue?
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
What does the tissue form?
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 is dead phloem called on a tree?
Dead phloem on a tree is called "inner bark" or "bast." It serves to transport nutrients within the tree but is no longer living tissue once it dies.
What is the effect of dead phloem?
dead phloem causes bark to formon atree

Phloem cells are alive at maturity and contain sieve tubes for nutrient transport, while xylem cells are dead at maturity and contain tracheids or vessel elements for water 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.
What tissue is responsible for forming secondary xylem and phloem in terrestrial perennial plants?
The vascular cambium is the tissue responsible for forming secondary xylem and phloem in terrestrial perennial plants. It is a meristematic tissue located between the primary xylem and primary phloem in the vascular bundles. The vascular cambium undergoes cell divisions to produce new cells that differentiate into secondary xylem towards the inside and secondary phloem towards the outside, contributing to the growth of the plant.
