Unterrichtsform
The course consists of lectures during which the Professor presents the different topics. Practical lessons and laboratory activities conducted by the Teacher and the Teaching Assistants are also foreseen. Course topics will be presented using Power Point presentations and at the end of a single lesson a pdf copy will be distributed directly to students. Interactive learning methods include student-led presentations revisiting and summarizing the most important concepts of the last lecture, followed by Q&A sessions, group-based/cooperative exercises, online self-assessment quizzes, and open discussions for feedback on teaching and learning approaches.

Bildungsziele
Knowledge and understanding of chemical transformations that matter undergoes in living organisms in relation to qualitative and quantitative aspects of both production practices and processing in agriculture. Capability in applying knowledge by developing practical laboratory skills and the ability to draw information out from practical laboratory activities in support/integration to the theoretical lessons. Making judgments based on the choice of analytical protocols, writing a report. Capability in presentation of the skills acquired with an appropriate language and use of technical and specific terms. Acquisition of learning strategies based on the use of technical information and knowledge updating.

Bildungsziele und erwartete Lernergebnisse (zus. Informationen)
• Develop the ability to connect biochemical and physiological concepts with practical agricultural applications through real-world case studies. • Strengthen problem-solving skills by designing and interpreting laboratory experiments related to plant metabolism, nutrition, and stress responses. • Enhance critical thinking through the analysis of scientific literature and the discussion of recent advances in plant biochemistry and physiology. • Improve teamwork, communication, and presentation skills through group-based activities and student-led summaries of lecture content. • Gain exposure to professional contexts and innovation in the agro-biotechnological sector through interaction with guest speakers/agro-industry representatives.

Art der Prüfung
Assessment is conducted via oral examination that includes: a) questions to assess the knowledge and understanding of the course topics. b) questions designed to assess the ability to transfer these skills to case studies of crop production. c) discussion of laboratory activities to evaluate the ability to apply theoretical knowledge in practical contexts. The oral exam may also include problem-solving questions and interpretation of experimental results discussed during the course.

Bewertungskriterien
Attribution of a single final mark. The evaluation considers the following criteria: • Knowledge and understanding of the subject matter (25%): depth, breadth, and accuracy of the student’s knowledge of plant biochemistry and physiology, including theoretical concepts, and key facts and data. • Clarity and accuracy of the response (20%): ability to explain concepts in a precise, coherent, and structured way. • Mastery of language (10%): correct and consistent use of scientific and technical terminology in English. • Ability to connect topics (20%): capacity to integrate knowledge across different areas of the course and relate theory to practice. • Independence of judgment (15%): originality of thought, critical analysis, and problem-solving ability. • Interpretation of laboratory activities (10%): correct explanation of experimental procedures, results, and their significance. Performance levels: • Excellent (28–30 cum laude): comprehensive and in-depth knowledge of the subject, precise and well-structured answers, excellent mastery of terminology, strong and original connections between topics, independent reasoning, and accurate interpretation of laboratory work. • Good (25–27): solid and accurate knowledge with minor gaps, generally clear explanations, good use of terminology, relevant connections between topics, and mostly correct interpretation of laboratory work. • Satisfactory (22–24): adequate knowledge with some minor inaccuracies, clear but not always detailed answers, sufficient mastery of terminology, limited but correct connections between topics, and acceptable interpretation of laboratory activities. • Sufficient (18–21): essential knowledge of the main topics, answers that are generally correct but may lack detail or depth, basic use of terminology, minimal but relevant connections between topics, and basic but correct interpretation of laboratory activities.
