9.1.U1 Transpiration is the inevitable consequence of gas exchange in the leaf.
9.1.U2 Plants transport water from the roots to the leaves to replace losses from transpiration.
9.1.U3 The cohesive property of water and the structure of the xylem vessels allow transport under tension.
9.1.U4 The adhesive property of water and evaporation generate tension forces in leaf cell walls.
9.1.U5Active uptake of mineral ions in the roots causes absorption of water by osmosis.
9.1.A1 Adaptations of plants in deserts and in saline soils for water conservation.
9.1.A2 Models of water transport in xylem using simple apparatus including blotting or filter paper, porous pots and capillary tubing.
9.1.S1 Drawing the structure of primary xylem vessels in sections of stems based on microscope images.
9.1.S2 Measurement of transpiration rates using potometers. (Practical 7)
9.1.S3 Design of an experiment to test hypotheses about the effect of temperature or humidity on transpiration rates.
