Which among the following is incorrect about different cells in Xylem?
  • a)
    Xylem fibers are perforated and help in conduction of water to branches
  • b)
    Xylem vessels have lignified walls without protoplasm
  • c)
    Xylem parenchymatic tissues are made of thin-walled living cells and conduct water sideways

Which among the following is incorrect about different cells in Xylem?...
Xylem is a complex tissue in plants that is responsible for the conduction of water and minerals from the roots to the other parts of the plant. It consists of several types of cells, each with its own unique structure and function. Among the given options, option A is incorrect.

Xylem fibers:
- Xylem fibers, also known as sclerenchyma fibers, are long, narrow cells with thick secondary cell walls.
- These fibers provide mechanical support and strength to the plant.
- Unlike other xylem cells, they do not have perforations or openings that allow the conduction of water.

Xylem vessels:
- Xylem vessels are tubular structures formed by the arrangement of individual cells called vessel elements.
- The walls of vessel elements are lignified, meaning they contain lignin, a complex polymer that provides strength and rigidity.
- The lignified walls of vessel elements are thickened and contain pits or perforations that allow the lateral movement of water between adjacent cells.
- Protoplasm, which includes the living components of a cell, is absent in mature vessel elements.

Xylem parenchyma:
- Xylem parenchyma consists of thin-walled living cells.
- These cells are involved in various functions such as storage, lateral conduction of water, and repair.
- They have primary cell walls and contain protoplasm, including a nucleus and other cellular components.

Tracheids:
- Tracheids are another type of xylem cells that are elongated and tapered.
- They have thick secondary cell walls with pits or perforations that allow water movement.
- Tracheids are dead cells at maturity and lack protoplasm.

Conclusion:
Among the given options, option A is incorrect because xylem fibers do not have perforations and do not directly participate in the conduction of water. They provide mechanical support to the plant. On the other hand, xylem vessels, xylem parenchyma, and tracheids are all involved in the conduction of water in different ways.
