Xylem cells are not living plant cells. They die so that they can form the thin tubes that conduct water upward via capillary action.
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.
Water conducting cells in xylem lack the organelles necessary for active transport functions, such as mitochondria and endoplasmic reticulum. Their main function is to conduct water and minerals through passive processes like transpiration and cohesion-tension. Additionally, active transport requires energy input, which the non-living xylem cells cannot generate.
Vascular tissue
The cells responsible for transporting water and minerals from the roots to the shoots in plants are called xylem cells. Xylem is a type of vascular tissue that forms a network of tubes to conduct water and minerals throughout the plant.
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.
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.
No xylem die at maturity but phloem stays alive all the time the plant is alive.
Xylem cells are in plants not animals.
Xylem cells are found in vascular plants.

xylem cells are present in the plant coducting tissue called xylem. they aren't in human body anywhere.
One is to transport the water and the minerals. The cells are adapted to this job because they do not contain cytoplasm so the water and minerals can travel through the xylem more easily. Two is to support the plant. Their walls have lignin (hard material)
No, xylem cells are "dead" cells and therefore do not undergo cell division.
- Walls made from dead lignin cells, which waterproof and support walls even if water levels are low in plants. - Narrow tubes so water column doesn't break easily. - Pits in walls allow water to move from one cell to another.
Vascular tissue
Xylem cells are permanent, non-dividing cells that originate from special meristematic cells called procambial cells during plant development. They cannot reproduce independently. However, plants can produce new xylem cells through the activity of the vascular cambium, a meristematic tissue located between the xylem and phloem.
the job of animal cell is to keep the animal alive
