Assertion and reason type questions:
1. Transportation and its types:
| Assertion: | The water, minerals and salts absorbed by the roots of the plants reach all the parts of the plant by the vascular tissue phloem. |
| Reason: | The food which is produced in the leaves of the plants is translocated to the other parts of the plant through the xylem. |
2. Transportation and Transpiration
| Assertion: | Transpirational pull is a suctional force which occurs due to transpiration. |
| Reason: | During transpiration water evaporates from the companion cells. |
3. Ascent of sap and translocation of solutes
| Assertion: | Translocation is a bidirectional process. |
| Reason: | Translocation in phloem occurs in upward and downward directions. |
