Plants need to regulate water in order to stay upright and structurally stable. Find out the different evolutionary adaptations of plants in terms of structure (e.g. stomata) and physiological mechanisms (e.g. root pressure, capillarity, transpiration pull, curving of leaves, etc.) that enabled them to maintain the appropriate water level...
Freshwater ecology focuses on the relations of aquatic organisms to their freshwater habitats. There are two forms of communities that thrive in freshwater: the lentic and the lotic communities. In these communities, plants and animals evolved special characteristics that make them better adapted to their habitat. Get to know more about these features and the..
