PLANT PHYSIOLOGY

Course objectives

General skills The course aims to provide knowledge on the physiological and biochemical mechanisms that allow plants to live in different environments. The course starts from the study of water and nutrient transports to reach important topics such as photosynthesis, photoreceptors and plant hormones. The student will acquire knowledge on the interaction between light, water and carbon dioxide. They will learn the biochemical mechanisms of photosynthesis in both light reactions and Calvin cycle. He will be able to distinguish between the various photosynthetic metabolisms (C3, C4, CAM) and to understand the molecular and physiological basis of the symbiotic interactions between plants and mycorrhizal fungi or nitrogen fixing bacteria. The initial contents of the course are linked to those of the courses of Cellular Biology, General and Inorganic Chemistry, Organic Chemistry, Biochemistry, Molecular and Botany Biology and Plant Diversity. The course includes theoretical and methodological lectures, dedicated to techniques and innovative approaches related to plant physiology and biotechnology. Specific skills A) Knowledge and understanding -Knowledge of the physiological and molecular mechanisms underlying the main physiological processes of the plant -Knowledge of the mechanisms by which the plant is able to transform light energy into chemical energy; -Knowledge of the mechanisms that allow the plant to recover mineral nutrients from the environment; -Understanding the main plant metabolic pathways. -Understanding the processes that plant exploits to react to environmental changes using hormones and photoreceptors. -Knowledge of basic techniques for the study of plant physiology. B) Applying knowledge and understanding The student will acquire the skills of: -Use the correct scientific terminology; -Predict the mechanisms by which the plant reacts to changes in environmental conditions; -Use the simplest techniques at the base of plant biotechnologies by planning simple experimental protocols C) Making judgements -The student will acquire autonomy of judgment in the recognition of the molecular mechanism at the base of plant physiology, for the adequacy of the various analytical techniques, for the interpretation of protocols of genetic transformation and for the interpretation of experimental laboratory data. -The student will learn to ask the right questions to himself for the elaboration and deepening of the knowledge learned. D) Communication skills The student will be stimulated to expose the concepts exposed in the classroom so that he can be able to correctly communicate the knowledge learned. E) Learning skills The student will acquire a study method that allows the understanding of specific topics related to plant physiology. He will acquire the ability to understand the specific terminology, logically connect the acquired knowledge obtaining mastery of the relevant themes of plant physiology.

Teaching mode
The course includes lectures and laboratory lessons with the use of telematic supports. Through lectures, students learn the fundamental knowledge of the discipline. The laboratories and methodological lessons are instead aimed at learning the main experimental approaches inherent to plant physiology. The student learns how to apply theoretical knowledge to concrete problems. The slides presented in class, including the methodological lessons, are provided to students in the online teaching materials on https://elearning.uniroma1.it/course/view.php?id=1334.
Frequency
Attendance of the classes is not mandatory, albeit strongly encouraged.
Exam mode
The final examination is an oral exam based on questions regarding the complete syllabus. Students can also choose to be examined with "in itinere" evaluation with three written tests. Results will be considered during the evaluation phase. Those unable to perform the "in itinere" evaluation can regularly participate to the oral examination on the official dates proposed.
