| Contents | THE WATER TRANSPORT: diffusion, bulk flow and osmosis. Hydric potential. solute transport: active and passive transport. Ionic channels, carrier and pumps. The membrane potential. Water and salt uptake: from soil to root, root pressure. Phytoremediation PHOTOSYNTHESIS: The pigments (chlorophylls, carotenoids and xanthophylls). The light phase of photosynthesis. The dark reaction: C3, C4 andCAMcycles. Photorespiration. Photosynthesis ecophysiology. PLANT METABOLISM: Assimilation of mineral elements: uptake and assimilation of nitrate. Synthesis of aminoacids. Biological fixation of nitrogen. SECONDARY METABOLITES: terpens, alkaloids and flavonoids. BIOTIC AND ABIOTIC STRESSES N. Rascio “Elementi di Fisiologia Vegetale” Edises II edizione 2017. Slides of the lectures are in the web site UNISTUDIUM. The course is aimed to furnish useful elements to the understanding of the plant metabolism. To achieve this objective the students must understand a) how the plants are able to use the solar energy to assimilate the inorganic carbon and to convert it through different biosyntheses into molecules and complex organic structures composing the plant cell; b) how the plants are able to take up mineral elements and water from the environment and to redistribute them inside the different parts of the plant; c) how the plants are able to develop and to regulate their own growth, also in relationship to the environmental stimuli. The mechanisms of the response and adaptation of the plants to stress conditions will be deepened with particular attention to formation and scavenging of reactive oxygen species. |

| Prerequisites | Prerequisite that the student must have to fully understand the contents of the course is the knowledge of general botany (Plant citology and morphology). Important prerequisite is considered the knowledge of fundamentals of general chemistry, inorganic and organic. |
| Teaching methods | Face-to-face lectures. |
| Learning verification modality | Final oral exam. Written reports to be submitted on each practical lesson attended, they will contribute 20% to the final grade of the exam.
