Definition of hydrophytic plants, macrophytes, characteristics of water habitats, types of water plants. Systematics of hydrophytic plants (obligate aquatic families, aquatic genera, aquatic species within terrestrial genera). Morphological and physiological adaptations to water habitats: adaptations of free floating plants, heterophyly, optimalization of leaf-shape, morphology, adaptations in lemnids; adaptations of submerged aquatic plants - CAM metabolism, Carbon absorption in various submerged aquatic plants, physiological adaptations to mineral nutrition, morphology of submerged aquatic plants. Generative reproduction of water plants, adaptation of emersed inflorescence, kleistogamy, flower architecture in Nymphaeales, evolutionary trends to hydrogamy. Seed ripening, dissemination. Exceptional reproduction modes. Clonal reproduction, types, genetic consequences. Hydrophytic plants in the Czech republic - an overview. Biotopes of aquatic plants, aquatic plant communities; indication potential of aquatic plants; role of aquatic plants for other organisms and water ecosystem; field excursion focusing on practical identification of important species of the water plants
