Definition: The use of living organisms (especially microorganisms) in industrial, agricultural, medical and other technological applications.

Alright class, settle down now, let’s dive into this today! We have a fascinating word here - "biotechnology." It’s something we hear about quite often, so let's really understand what it means. The dictionary gives us a good starting point: “The use of living organisms… in industrial, agricultural, medical and other technological applications.” Let’s break that down with a little rhyme to make it stick! (Pause for effect) "Biotechnology," you see, is quite the treat, It uses life – tiny and complete! From microbes small, a marvelous crew, To help us build things, shiny and new. Think of it like this: we’re not just using machines, But harnessing nature with clever scenes. Industrial applications? Like making enzymes for cleaners bright, or building materials strong and light! Agricultural uses? Growing crops that are resistant to disease, a bountiful harvest with ease! Medical marvels? Developing drugs and cures, using genes to fight back, it's pure! Essentially, we’re taking what living things can do – their amazing abilities – and putting them to work in all sorts of helpful ways. We manipulate these organisms (bacteria, yeast, plants… you name it!) to achieve a specific goal. Does that make sense so far? Don't hesitate to ask if anything is unclear. Now, who can give me an example of how biotechnology might be used in medicine?
