Assertion In angioperms, the conduction of water is more efficient because their xylem has vessels.
Reason Conduction of water by vessel elements is an active process in which energy is supplied by xylem parenchyma rich in mitochondria.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
B. It both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
C. If Assertion is true statement but Reason is false.
D. It both Assertion and Reason are false statements.

Answer

c

Explanation

Xylem is the main conducting tissue in plants. It consits of 4 different components-trachceids, trachea or vessels , xylem fibre and xylem parenchyma. Tracheids are elongated cell ferns and gymnosperms for conduction of water. In angiosperms vessels are composite structure as these are formed by dissolution of end cells with tapering end. They are generally present in firns and gymnosperms for conduction of water. In angiosperms, vessles are composite structure as these are formed by dissolution of end walls of row of cell. i.e., vessels elements. so angiosperms, have more efficient system of conduction due to presence of vessels. Conduction of water by vessel elements is also known as ascent of sap. Water absorbed by roots, goes upward to replace the water absorbed buy roots hair is passed through vessles to the leaves. The xylem parenchyma are mainly and due to this water absorbed by roots hair is passed through vesseles to the leaves. the xylem parenchyma are mainly for storage. function but sometimes help in conduction.
