Bio-engineered refers to the process of using biological systems or living organisms to create or modify products, often for specific purposes. This can include altering the genetic makeup of plants, animals, or microorganisms to enhance desirable traits, such as increased resistance to pests or improved nutritional content. One common example of bio-engineering is the development of genetically modified organisms (GMOs), which are used in agriculture to produce crops that can withstand harsh conditions. Bio-engineering also plays a role in medicine, where it can be used to create bio-pharmaceuticals or develop new treatments for diseases.
