Arrange and rewrite the terms in each group in the correct order to be in a logical sequence beginning with the term that is underlined:
Water vapour, SOIL WATER, Leaves, Ascent of Sap. (Begin with: Soil water)
Topic: Path of water through the plant
Answer
Soil water → Ascent of Sap → Leaves → Water vapour
This traces one molecule of water from the soil to the atmosphere: SOIL WATER — absorbed by the root hairs by osmosis ASCENT OF SAP — carried up the stem through the XYLEM LEAVES — reaches the mesophyll cells WATER VAPOUR — evaporates and is lost through the stomata as transpiration
THE DRIVING FORCE is worth stating: the evaporation at the top creates the TRANSPIRATION PULL, a suction that draws the whole unbroken column of water up the xylem — which is what makes the ascent of sap possible against gravity, sometimes to the top of a very tall tree.
So the last step in the sequence is actually the cause of the second.
