Match the items in column I with those in column II. Column I Column II 1. Xylem a. Semipermeable 2. Phloem b. Permeable 3. Cell membrane c. Downward flow of sap 4. Root pressure d. Upward flow of water 5. Cell wall e. Guttation

(1)-(d) Xylem is a conducting tissue that conducts water in the plant. (2)-(c) Phloem is a conducting tissue that conducts food in the plants from leaves to roots. (3)-(a) The cell membrane is semipermeable or selectively permeable. (4)-(e) Root pressure creates guttation at night in some plants. (5)-(b) The cell wall is seen in plant cells and it is permeable.
