Non-conducting xylem cells are found in the heartwood of trees. As a tree ages, the inner layers of xylem cells lose their ability to conduct water and become filled with resins, gums, and other substances that help provide structural support to the tree.
- 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.
No, xylem cells are "dead" cells and therefore do not undergo cell division.
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.
No, dead xylem and phloem cells do not turn into cambium. The cambium is a layer of actively dividing cells in the vascular system of plants that gives rise to new xylem and phloem cells. Dead xylem and phloem cells are typically used for structural support or transport of water and nutrients, and they do not have the ability to transform into cambium cells.

Xylem and phloem
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.

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.
Wood grows and develops from a seedling into a mature tree through a process called secondary growth. This involves the formation of new layers of wood underneath the bark, which increases the tree's girth over time. As the tree grows, cells in the cambium layer divide and differentiate into xylem and phloem tissues, with xylem cells forming the wood. These xylem cells provide structural support and transport water and nutrients throughout the tree. Over many years, these layers of wood accumulate, resulting in the growth of the tree and the formation of its characteristic woody trunk.
