Describe ONE mechanism of transportation in plant. – NABTEB QUESTION

1. Root pressure
2. soil water flows into cell sap or root hairs
3. water in the root hairs moves into xylem vessels through the cortex, endodermis, and per cycle
4. water in the xylem vessels or the root is moved into the xylem of the stem branches and leave under root pressure. OR
5. Suction pressure/transpiration pull/unbroken water column
6. As water passes from soil into roots, stem, and leaves suction pressure is set up
7. as excess water is evaporated from the leaves an unbroken water column is maintained in the xylem vessels
8. as transpiration continues, a transpiration pull is set up.
