Portal:Biology - Wikipedia, the free encyclopedia
Welcome to the biology portal. Biology, from the Greek words bios (life) and the suffix -ology, meaning study of, is a branch of science. It is concerned with the characteristics and behaviors of organisms, how species and individuals come into existence, and the interactions they have with each other and with their environment. Biology encompasses a broad spectrum of academic fields that are often viewed as independent disciplines. Together, they study life over a wide range of scales.
Blue has been chosen as the colour for this portal to emphasise that life on Earth relies on the unique chemistry of water. A photo of Darlingtonia californica, the cobra lily, was chosen as the portal icon because of this species' dependency on a humid habitat, as well as illustrating both autotrophy (in this case, photosynthesis) and carnivory. Finally, it superficially resembles young shoots, with their tips curved in, symbolising growth, a feature of all life.
