The biology represents set of sciences about living beings and their interaction with the environment. Three main sections of biology: botany, zoology and microbiology.
Botany and its disciplines
The first large biological science – botany. She is engaged in studying plants. The botany is divided into a set of disciplines which can also be considered biological. Algology studies seaweed. The anatomy of plants studies the structure of fabrics and cages of plants and also under what laws these fabrics develop. Briologiya studies plant Bryophyta, dendrology – wood. The carpology studies seeds and fruits of plants.
Likhenologiya – science about lichens. A mycology – about mushrooms, a mikogeorgafiya – about their distribution. Paleobotany – the section of botany which studies fossil remains of plants. The palynology studies pollen grains and disputes of plants. The science systematization of plants is engaged in their classification. The phytopathology studies various diseases of plants caused by pathogenic and ecological factors. The floristics studies the flora which historically developed in a certain territory set of plants.
The science of the ethnobotanist studies interaction of people and plants. Geobotany – science about Earth vegetation, about vegetable communities – phytocenosis. The geography of plants studies regularities of their distribution. Morphology of plants – science about regularities of the structure of plants. Physiology of plants – about functional activity of organisms of plants.
Zoology and microbiology
The second large section of biology is called zoology, it is engaged in studying animals. In this section there are also a lot of disciplines. Akarologiya studies ticks. Physical anthropology – science about origin and evolution of human races. Apiologiya studies honey bees, arachnology – arachnoid, helminthology – helminths, herpetology – Amphibia and reptiles. Ichthyology – science about fishes, a kartsinologiya – about Crustacea, a ketologiya – about cetacea, a conchology – about mollusks, a mirmekologiya – about ants, a nematologiya – about roundworms, an oologiya – about eggs of animals, ornithology – about birds. The paleozoology studies fossil remains of animals, a planktologiya – plankton, primatology – primacies, a teriologiya – mammals, entomology – insects, protozoology – monocelled. The ethology is engaged in studying instincts of animals. The third large section of biology – microbiology. This science studies living organisms invisible with the naked eye: bacteria, Archean, microscopic mushrooms and seaweed, viruses. Also sections are respectively selected: virology, mycology, bacteriology, etc.
