Bot. 315 PLANT PHYSIOLOGY I (1+3): 2

Bot. 315 PLANT PHYSIOLOGY I (1+3): 2
Plant-water Relationships: A. Water and plants- classification of plants according to water availability- water cycle- the role of water in plants- water content of plants. B. Chemical and physical properties of water. C. Water and soil: soil properties- soil water- water movement in the soil- determination of soil-water content. D. Cell-water relationships: cell structure- Terminology in plant-water relationships: Plasmolysis- cell permeability-water movement within the cell- determination of water potential component in plants. E. Water movement to the plant: Root structure- movement of water to the xylem- factors affecting water absorption- the ascent of sap in the xylem. F. Loss of water from the plant: Transpiration- leaf anatomy- transpiring surfaces- stomata- measurement of transpiration- factors affecting the rate of transpiration.
