Plants live everywhere, populating all major habitats (air, land, water). Their life cycle takes place under the influence of environmental factors and is therefore subject to large variations in abiotic factors. In this context, plants have changed over time their structures, organ shape and appearance, resulting from their adaptation to living environment. Some changes in the structure and function of the vegetative organs, arising as a result of their adaptation to the plant were followed by one of the greatest figures in literature and the founder of morphology as a science – J.W. von Goethe, who in 1790 formulated a theory of plant metamorphosis (adaptive change). This paper highlights such adaptive changes but seeks and identifies chemical elements in plant composition under study (Hydrocharis morsusranae, Anubias barteri, Hygrophila odora, Bacopa caroliniana) – the first step in trying as thorough knowledge of aquatic plants to establish their possible uses.
