Detailed explanation-1: -Xylem helps in transportation of water. The cell wall of cells making up the xylem contains lignin. This lignin is water resistant and provides mechanical support to the xylem. Q.
Detailed explanation-2: -The cells of xylem are dead at maturity and devoid of protoplasm except for xylem parenchyma cells, which are living cells.
Detailed explanation-3: -The xylem is a tissue which transports water and minerals from the roots up the plant stem and into the leaves. Xylem consists of dead cells. The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube.
Detailed explanation-4: -They do not have any protoplasm at maturity. Tracheids are dead, tapered, and long lignified cells that are present in the xylem of plants. They are one of the water-conducting components in the xylem, which doesn’t have any protoplasm.
