General plant physiology

Course Description: Theoretical: - The plant cell / Solutions (types, role of each solution in cell function) / Water relations (osmotic pressure, water potential, water relations equations and their application) / Soil and plant nutrition (macro and micronutrients - physiological role of each element - deficiency symptoms - treatment methods) / Phloem transport (movement of nutrients within conducting tissues) / Photosynthesis and its influencing factors / Respiration (aerobic and anaerobic respiration - influencing factors) / Plant hormones (auxins, gibberellins, cytokinins, inhibitors, and their role in agriculture) / Enzymes - definition - physiological role - mechanism of action - enzyme inhibitors / Nitrogen transformations (symbiotic and non-symbiotic nitrogen fixation) / Environmental physiology (types of environmental stress - environmental pollution - treatment methods). Practical: - Preparation of various solutions and their precipitation / Microscopic study of the plant cell / Study of osmosis and diffusion experiments / Demonstration of photosynthesis in green plants / Demonstration of aerobic and anaerobic respiration in plants / Extraction and determination of photosynthetic pigments / Experiments on enzyme activity.
