Reason: Transportation in plants takes place with the help of vascular tissues.
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
