| ANIMAL AND VEGETABLE ORGANISMS 'REPLIES TO ENVIRONMENTAL STRESSES
(objectives)
Environmental stress, including temperature variation, hypoxia, and pollutants, deleteriously affects the functions of both animals and plants disrupting their homeostasis. Understanding the organism responses to environmental stress and the underlying mechanisms are essential to complete student formation in science and technology for environment. The expected learning outcomes are related to Plant Physiology, Ecophysiology, Physiology, Comparative Physiology, Environmental Physiology. In particular, the Educational Objectives are related to the acquisition of Cultural Competencies concerning the knowledge of: physiological terminology; homeostasis; phenotype plasticity; functional acclimatization of animals and plants. Teaching Objectives are also the acquisition of Methodological Skills, concerning the ability to carry out application of the scientific method for the analysis of components and factors of processes, systems and problems concerning the environment, both natural and modified by human beings and experimental data processing

PLANT RESPONSES TO ENVIRONMENTAL STRESSES
Effects of climate changes on plants. Environmental stresses. Plant responses to environmental stresses. Stress resistance and susceptibility in plants. Avoidance, defense and tolerance strategies. Adaptation and acclimatization. Phenotypic plasticity: morphological, physiological, biochemical and metabolic plasticity.
Indeterminate growth: primary meristems and stem cells. Elongation growth: cell wall role. Morphogens. Photomorphogenesis. Tropisms.
Plant water balance. Water potential. The movement of water and solutes in plants. Stomata: structure, and regulation of the stomatal opening.
Photosynthesis: adaptations and acclimatization of the photosynthetic process to different climatic conditions. Photorespiration in C3 metabolism. C4 metabolism and acid metabolism of crassulaceae (CAM). Physiological and ecological considerations of photosynthesis. Interception of sunlight: leaf anatomy, leaf movement, chloroplast rotation, chlorophyll a/chlorophyll b ratio, the role of antenna complexes. Plant responses to the excess of light energy. The dissipation of excess energy. The photo- inhibition.
Adaptations and acclimatization to abiotic stresses: water deficit, saline stress, excess water and oxygen deficiency, high and low temperatures.
Secondary metabolism: definition and ecological role of secondary metabolites. The main classes of secondary metabolites: terpenes, nitrogen-containing compounds and phenols.
