  • 1. 08/09/13 B5 TransportationB5 Transportation Syllabus statementsSyllabus statements
  • 2. 5.1 Transport in plants5.1 Transport in plants
  • 3. 5.1 Transport in plants5.1 Transport in plants 1. State the functions of xylem and phloem. 2. Identify the positions of xylem and phloem tissues as seen in transverse sections of unthickened, herbaceous, dicotyledonous roots, stems and leaves.
  • 4. 5.1 Transport in plants5.1 Transport in plants 3. Identify root hair cells, as seen under the light microscope, and state their functions. 4. Relate the structure and functions of root hairs to their surface area and to water and ion uptake.
  • 5. 5.1 Transport in plants5.1 Transport in plants 5. State the pathway taken by water through root, stem and leaf (root hair, root cortex cells, xylem, mesophyll cells). 6. Investigate, using a suitable stain, the pathway of water through the aboveground parts of a plant.
  • 6. 5.1 Transport in plants5.1 Transport in plants 7. Define transpiration as evaporation of water at the surfaces of the mesophyll cells followed by loss of water vapour from plant leaves, through the stomata. 8. Describe how water vapour loss is related to cell surfaces, air spaces and stomata.
  • 7. 5.1 Transport in plants5.1 Transport in plants 9. Describe the effects of variation of temperature, humidity and light intensity on transpiration rate. 10. Explain the mechanism of water uptake and movement in terms of transpiration producing a tension (‘pull’) from above, creating a water potential gradient in the xylem, drawing cohesive water molecules up the plant.
  • 8. 5.1 Transport in plants5.1 Transport in plants 11. Define translocation in terms of the movement of sucrose and amino acids in phloem; from regions of production to regions of storage OR to regions of utilisation in respiration or growth.
