Biology is the teaching of living things, life forms and life phenomena. Biology has many sub-areas and divisions such as level, taxonomic, processes or ecological classification.
Where does biology come from
Biology is the teaching of living things, life forms and life phenomena. It is counted among the exact sciences. The term biology comes from the (scientific) Latin, from the word Biologia. This is again constructed by the scientists from two Ancient Greek words, namely bios and logios. Bios means: life. Logios means: learned.
Sub-areas Biology
Biology has many sub-areas which are classified in different ways. A commonly used classification is on grade.
Possible classifications of biology:
- Classification by level
- Taxonomic Classification
- Classification by processes
- Ecological classification
Biology classification by level
- Molecular level (submicroscopic): Biochemistry, Molecular biology and Molecular genetics.
- Cell level (microscopic): Cell Biology (Cytology or Microfysiology).
- Tissues: Histology and Neurobiology (Microfysiology).
- Systems (macroscopic): Physiology (Macrophysiology) and Endocrinology.
- Individuals: Macrophysiology, Morphology and Anatomy.
- Species: Taxonomy, Evolutionary Biology, Anatomy and Morphology.
- Populations: Population Biology and Ethology.
- Ecosystems: Ecology, Vegetation Science and Environmental Biology.
Taxonomic Classification
- Viruses: Virology.
- Microscopic Organisms: Microbiology.
- Plants: Botany.
- Animals: Zoology and its specializations such as Ornithology (birds) and Entomology (insects).
Classification by processes:
- Heredity: Genetics.
- Development: Developmental Biology.
- Evolutionary Historical: Paleontology.
- Illness and health: Immunology, Epidemiology, Phytopathology and Toxicology.
Ecological classification
- Water: Aquatic Biology and Marine Biology.
- Country: Terrestrial ecology.
- Forest: Forestry.
