1. Microscopes & Lab Techniques

2. What is a light microscope? Light Microscope – a device that uses light to produce an enlarged view of an object An example of a simple microscope is a magnifying glass

4. What is a compound microscope? Compound Microscope – contains 2 or more objective lenses. – One lens (low power) produces an enlarged image – Another lens (high power) further magnifies the image

6. Magnification vs. Resolution Magnification – the enlargement of an image Resolution – how sharp or in focus an object is

7. What is an electron microscope? Electron Microscope – can magnify images more than 250,000 X – Uses electron beams rather than light

8. A Scanning Electron Microscope

9. An ant

10. Leaf from a Black Walnut tree

11. Pollen

12. A moth

13. A human skin cell

14. A cancer cell

15. Centrifugation Centrifugation – a process by which materials suspended in a liquid can be separated from each other based on density

16. Microdissection Microdissection – tiny instruments are used to perform various operations on living cells

17. Tissue Culture Tissue Culture – the technique of maintaining living cells or tissues in a culture medium outside the body

18. Chromatography Chromatography – any technique that separates different substances based on their chemical and physical properties

19. Electrophoresis Electrophoresis – the technique for separating substances made up of particles that have an electrical charge

21. Spectrophotometry Spectrophotometry – a technique of using light to analyze samples
