Biology 1.1

Biology is the study of living organisms including their structure, function, growth, evolution, distribution, and taxonomy. It recognizes the cell as the basic unit of life and genes as the basic unit of heredity. Subdisciplines study organisms at different scales and use various methods, such as biochemistry examining life's basic chemistry, molecular biology studying interactions between biological molecules, and ecology examining relationships between organisms and their environments. Modern biology is founded on cell theory, evolution, genetics, homeostasis, and understanding energy as central to how organisms survive and function.

Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.[1] Modern biology is a vast and eclectic field, composed of many branches and subdisciplines. However, despite the broad scope of biology, there are certain general and unifying concepts within it which govern all study and research, consolidating it into single, coherent field. Biology generally recognizes the cell as the basic unit of life, genes as the basic unit of heredity, and evolution as the engine that propels the synthesis and creation of new species. It is also understood today that all organisms survive by consuming and transforming energyand by regulating their internal environment to maintain a stable and vital condition. Subdisciplines of biology are defined by the scale at which organisms are studied, the kinds of organisms studied, and the methods used to study them: biochemistry examines the rudimentary chemistry of life;molecular biology studies the complex interactions among biologicalmolecules; botany studies the biology of plants; cellular biologyexamines the basic building block of all life, the cell; physiologyexamines the physical and chemical functions of tissues, organs, andorgan systems of an organism; evolutionary biology examines theprocesses that produced the diversity of life; and ecology examines how organisms interact in their environment.[2]
