4. Describe the effects of wind, temperature, humidity and light on transpiration rate.
5. Describe how wilting occurs.
6. Explain how water flows through the roots and stem using the terms "root pressure", "capillarity pull/capillary action" and "transpirational pull".
7. Draw a section through a stem, labelling xylem, phloem, cambium and pith.
8. State the functions of xylem and phloem.
9. Relate the structure of the xylem and phloem to their functions.
