Biotechnology (sometimes shortened to "biotech") is the use of living systems and organisms to develop or make useful products, and it is usually seen in agriculture, food productionand medicine production. Modern use of similar terms includes genetic engineering as well as cell and tissue culture technologies. The concept encompasses a wide range of procedures(and history) for modifying living organisms according to human purposes — going back to domestication of animals, cultivation of plants, and "improvements" to these through breedingprograms that employ artificial selection and hybridization. By comparison to biotechnology, bioengineering is generally thought of as a related field with its emphasis more on highersystems approaches (not necessarily altering or using biological materials directly) for interfacing with and utilizing living things. The United Nations Convention on BiologicalDiversity defines biotechnology as:
"Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes forspecific use."
In other terms: "Application of scientific and technical advances in life science to develop commercial products" is biotechnology. Biotechnology draws on the purebiological sciences (genetics, microbiology, animal cell culture, molecular biology, biochemistry, embryology, cell biology) and in many instances it is also dependent on knowledge andmethods from outside the sphere of biology (chemical engineering, bioprocess engineering, information technology, biorobotics). Conversely, modern biological sciences (including evenconcepts such as molecular ecology) are intimately entwined and dependent on the methods developed through biotechnology and what is commonly thought of as the life sciences industry
