View SolutionGiven below are two statements in relation to the limitations of the capillarity theory of water transport in plants.
Statement $I$: Xylem, i.e., the capillarity tube, must be with closed end walls and not hollow.
Statement $II$: The capillarity tube, i.e., xylem, is not in direct contact with soil water and contains a barrier of root cells between the xylem and soil water.
In the light of the above statements, choose the most appropriate answer from the options given below:
