Biotechnology is a rapidly advancing field that uses biological systems, organisms, or their derivatives to develop or modify products and processes for specific use. In simpler terms, biotechnology involves using living organisms or systems to make products that benefit humans.
Detailed Explanation
Biotechnology is essentially a blend of biology and technology. It focuses on using living organismsโlike plants, animals, and microbesโto create products that can improve various aspects of human life. This can mean anything from medical advancements, such as drugs and vaccines, to agricultural innovations like pest-resistant crops. When we break it down, biotechnology harnesses the natural capabilities of these organisms to solve problems and develop new solutions for challenges in health, environment, and industry.
Examples & Analogies
Think of biotechnology like baking a cake. You take different ingredients (organic matter) and combine them (processes) to create something new and usefulโjust like how biotechnologists use living cells to create medicines or improve food crops.
