Statement I: | The forces generated by transpiration can lift a xylem-sized column of water over 130 meters height. |
Statement II: | Transpiration cools leaf surfaces sometimes 10 to 15 degrees, by evaporative cooling. |
I: | The process of translocation through phloem is unidirectional but through xylem, it is bidirectional |
II: | The most readily mobilized elements are phosphorus, sulphur, nitrogen and potassium. |
