Detailed explanation-1: -Xylem fibres are non-living sclerenchyma cells. Because of their elasticity and tensile strength, they are an important component of the xylem. They protect and provide mechanical support to the xylem’s major water-carrying tissues. Water is transported through xylem fibers.
Detailed explanation-2: -Xylem fibre: These are dead cells having lignin content and central cavity. Help in the transportation and provide mechanical strength to the plants.
Detailed explanation-3: -4. Prosenchyma: these are thick-walled elongated cells, which give rigidity and strength to the plant.
Detailed explanation-4: -Xylem is the tissue of vascular plants that transports water and nutrients from the soil to the stems and leaves. Xylem plays an essential ‘supporting’ role providing strength to tissues and organs, to maintain plant architecture and resistance to bending.
Detailed explanation-5: -The walls of xylem cells are lignified (strengthened with a substance called lignin ). This allows the xylem to withstand pressure changes as water moves through the plant.
