Answer:A microscope is an instrument that can be used to observe small objects, even cells. The image of an object is magnified through at least one lens in the microscope. This lens bends light toward the eye and makes an object appear larger than it actually is. A microscope lets the user see the tiniest parts of our world: microbes, small structures within larger objects and even the molecules that are the building blocks of all matter. The ability to see otherwise invisible things enriches our lives on many levels. Microscopes play a crucial role in medical research and testing, as well as helping forensic scientists investigate crimes. They're also used in education. In the classroom, microscopes are used to teach students about the structure of things too small to be seen with the human eye alone. The individual cells of plants, animals, bacteria and yeast can all be seen using a compound microscope. Comparing these organisms helps students learn about the variety of life on Earth. Also, the way in which microscopes work can be used to teach students about the properties of light, the physics behind lenses and mirrors and staining techniques for various specimens. Additionally, individual parts of the cell can be seen as students learn about their specific functions.
