Vascular plants CFU

• Explain why roots are hypertonic relative to the soil.

• Outline the role of active transport in maintaining root tonicity.

• Describe how water enters roots from the soil.

• Compare the symplastic and apoplastic pathways of water transport through the root.

9.1.U2:  Plants transport water from the roots to the leaves to replace losses from transpiration

• Outline structures and mechanisms involved in the flow of water from roots to leaves. 

9.1.U4:  The adhesive property of water and evaporation generate tension forces in leaf cell walls.

• Explain the decrease in pressure and transpiration-pull that results from evaporation of water from the leaf.

• State that transpiration is a passive process. 

9.1.U3:  The cohesive property of water and the structure of the xylem vessels allow transport under tension

• Describe structure of xylem. 

• Outline how xylem is able to maintain rigidity even under low pressure or mechanical disturbance. 

• Outline polarity of water molecules.

• Define cohesion.

9.1.A2:  Models of water transport in xylem using simple apparatus including blotting or filter paper, porous pots and capillary tubing

• Explain use of models in science.

• Describe simple models of water transport, inclusive of evaporation, adhesion and cohesion. 

9.1.NOS:  Use models as representations of the real world-mechanisms involved in water transport in the xylem can be investigated using apparatus and material that show similarities in structure to plant tissues

• State a similarity and a difference between transpiration models and transpiration in plant tissues.

• Describe the use of a potometer to measure transpiration rates.

9.1.S3:  Design of an experiment to test hypothesis about the effects of temperatures or humidity on transpiration rates

• Identify the manipulated, responding and controlled variables in an experiment to test the effect of an abiotic factor on the rate of transpiration.
