What this unit covers

• Xylem and phloem: Describe the roles of xylem in moving water and mineral ions, as well as providing structural support, and the roles of phloem in transporting sucrose and amino acids.
• Xylem and phloem: Recognize and locate xylem and phloem in diagrams and images of cross-sections from the roots, stems, and leaves of non-woody dicotyledon plants.
• Water uptake: Recognize root hair cells in diagrams and describe their roles.
• Water uptake: Summarize the route that water follows through root hair cells, root cortex cells, xylem, and mesophyll cells.
• Transpiration: Explain how transpiration involves the release of water vapour from the leaves of plants.
• Transpiration: Examine and explain how changes in temperature and wind speed influence the rate of transpiration.
