LEARNING OUTCOMES – Plant Physiology Practicum
Course description and aim
The Plant Physiology Practicum course focuses on acquiring practical laboratory skills and developing a comprehensive understanding of plant physiological processes through experimentation. Students learn to apply and interpret various experimental approaches — from the extraction and chromatography of pigments and measurement of photosynthesis and respiration, to water relations, nutrient deficiency assessment, phytohormone effects, in vitro culture, and mycorrhizal symbiosis analysis. The aim of the course is to ensure that students not only conduct standard physiological experiments but also understand their purpose, interpret results critically, identify potential methodological limitations, and propose improvements.
Student performance is assessed through laboratory reports, which must document individual results, analysis, and evaluation of the experimental process and outcomes.
Learning Outcomes1. Knowledge and Understanding (Remembering / Understanding)
After completing the course, the student:
explains the principles of basic plant physiology methods (chromatography, spectrophotometry, fluorometry, gas exchange and transpiration measurements, osmotic potential determination, in vitro culture),
describes the physiological basis of photosynthesis, respiration, water relations, mineral nutrition, phytohormonal regulation, and mycorrhizal symbiosis,
understands the significance of experimental models for studying plant function and responses.
2. Application (Applying)
The student:
independently performs basic laboratory experiments in plant physiology, handling instruments and samples safely and effectively,
applies theoretical principles in designing and implementing small-scale experiments,
records, processes, and clearly presents experimental data.
3. Analysis (Analyzing)
The student:
identifies relationships between experimental conditions and physiological plant responses,
analyzes collected data in the context of biological variation and methodological limitations,
evaluates how different experiments contribute to understanding plant functioning in changing environments.
4. Synthesis (Creating)
The student:
integrates knowledge from different topics of plant physiology into a coherent understanding of plant functioning,
proposes modifications or extensions of experimental designs to test new hypotheses,
formulates well-structured conclusions based on observed data and physiological reasoning.
5. Evaluation (Evaluating)
The student:
critically assesses the reliability and validity of experimental data,
identifies possible sources of error and suggests improvements in methodology,
interprets results within a broader biological and ecological framework, supporting arguments with experimental evidence.
Final competencies of the course graduate
A graduate of the Plant Physiology Practicum course:
possesses fundamental theoretical knowledge and practical proficiency in experimental plant physiology,
can independently plan, perform, and interpret physiological experiments,
demonstrates critical thinking and scientific reasoning skills,
is capable of accurate and concise written communication of experimental results in the form of laboratory reports,
exhibits methodological accuracy, responsibility, and teamwork in laboratory settings.
