SYNOPSIS The course discusses some important aspects of the functional processes in plants. It includes the relation of water to plants and the acquisition of inorganic nutrients, the significance of roots, root-soil interaction and assimilation of nitrogen. The principles of energy transduction and carbon metabolism, the fundamental aspects of cell enlargement, plant hormone, plant movement, photomorphogenesis, and stress physiology are also discussed. (Kursus ini membincangkan sebahagian aspek yang penting dalam fungsi tumbuhan. Ini termasuklah perkaitan air dengan tumbuhan, keperluan nutrien inorganik, kepentingan akar, interaksi akar-tanah dan asimilasi nitrogen. Prinsip-prinsip pemindahan tenaga dan metabolisma karbon, aspek asas pembesaran sel, hormon tumbuhan, pergerakan tumbuhan, fotomorfogensis dan fisiologi kepayahan juga disentuh.)

LEARNING OUTCOMES: Students will be able to: 1. Distinguish specific pathways involved in plant transportation, photosynthesis, photomorphogenesis, movement, regulation and their mechanisms. (C4) 2. Conduct experiments scientifically and conclude their observations. (P4)

3. Justify the importance of abiotic factors such as water, mineral, and light in plant growth and development. (A3) 4. Organize a symposium to discuss, exhibit and present their mini projects. (L2S, CS3, P4) References 1. Berg, L. (2008). Introductory Botany: Plants, People and the Environment (2
