Question:

Write a note on Xylem​

Answer:

• The plant structure and additionally the anatomical structure tissue conjure the object of a plant and transports water, sugars and totally completely different necessary substances around a plant.

• Its ordinarily remarked as ‘sap’ is that the substances that are being transported around a plant by its plant part and phloem.

• The separation between plants that have veins and plants that don't is one in every of the good divides within the plant kingdom.

• This separates plants into tube and non-vascular plants. Most plants have plant tissue and vascular tissue and are spoken as vascular plants but thus Pine Tree State a lot of straightforward plants, love mosses and algae, don't have plant part or bast and are mentioned as non-vascular plants.

• Bast and natural object are closely associated and are usually found right next to a minimum of one another.

• One plant tissue and one anatomical structure tissue is assumed as a ‘vascular bundle’ and most plants have multiple tube bundles running the length of their leaves, stems and roots.

• Plant tissue is utilized primarily for transporting water from roots to stems and leaves but together transports totally completely completely different dissolved compounds.

• Plant tissue is in control of transporting food created from activity from leaves to non-photosynthesizing elements of a plant resembling roots and stems.

The different types of xylem are as follows :

• TRACHEIDS

• VESSEL  

• XYLEM PARENCHYMA

• XYLEM FIBRES

Features  of xylem :

• Xylem is the crucial tissue gift withinside the vascular plants, that is liable for transporting the water and the alternative vitamins from soil to leaves and stems.

• Xylem is in any other case referred to as as wood and it is one of the precious renewable assets within side the world.

• Xylem performs an critical position in helping and strengthening the tissues and organs and keeps plant structure and resistance to bending.

• The chemical, organic and bodily homes of the xylem cell are decided through the frequency, morphology and distribution and through ensuing the homes of the wood.

Answer 2

Answer:

Xylem is a type of complex tissue which collectively performs the function of transportation of water and mineral salts from root to leaves in plants. The tissues of xylem are derived from primary meristem. The xylem is usually made up of four types of cells: tracheids, vessels, fibers and parenchyma.

Tracheid: They are elongated dead cells with both ends tapering. They are found in xylem of gymnosperms, pteridophytes and angiosperms.

Vessels: vessels are rows of cells placed one above another. It represents a pipe or tube like structure by cells in a row. The cells are dead and wide. Vessels give mechanical support to the xylem and help in water conduction.

Xylem fiber: They are dead sclerenchyma cells. They are usually found in primary and secondary xylem. The walls of these cells are very thick. Fibers provide mechanical strength to the plant.

Xylem parenchyma: This is the only living cell found in xylem. The cell wall is thin and stores food materials.
