Biology

Biology is the study of living organisms and how they interact with their environment, dealing with every aspect of life in a living organism. Biology examines the structure, function, growth, origin, and distribution of living things. It classifies and describes organisms, their functions, and the interactions they have with each other and the natural environment. Biology as a separate science was developed in the nineteenth century as scientists discovered that organisms shared fundamental characteristics. Biology is now a standard subject of instruction at schools and universities around the world, and over a million papers are published annually in a wide array of biology and medicine journals.

Most biological sciences are specialized disciplines. Traditionally, they are grouped by the type of organism being studied:

  • Botany, the study of plants
  • Zoology, the study of animals
  • Microbiology, the study of microorganisms

The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them:

  • Biochemistry examines the fundamental chemistry of life
  • Molecular biology studies the complex interactions of systems of biological molecules
  • Cellular biology examines the basic building block of all life, the cell
  • Physiology examines the physical and chemical functions of the tissues and organ systems of an organism
  • Ecology examines how various organisms and their environment interrelate
