front 1 What is a microscope? | back 1 A piece of scientific equipment that makes it possible to study and explore specimens that are too small to view with the naked eye. |

front 6 A light microscope can either be... | back 6 Simple or compound |
front 7 What is resolution? | back 7 The ability to distinguish between two objects |
front 8 The greater the resolution the... | back 8 smaller the distance between them |
front 9 What is the normal resolution of the human eye? | back 9 about .2 mm |
front 10 The best microscopes are able to magnify up to what? | back 10 2,500x |
front 11 True or false. The microscope has two ocular lenses (binocular). | back 11 True |
front 12 The ocular lens magnifies the image by a factor of what? | back 12 10 times |
front 13 What is the objective lenses? | back 13 The revolving nosepiece that contains a set of objective lenses. |
front 14 What do the lenses do? | back 14 Allow you to change the degree of magnification. |
front 15 What are the 4 scanning objectives? | back 15 1. 4x scanning 2. 10x low power 3. 40x high power 4. 100x oil immersion |
front 16 Why is referred to as the oil immersion objective? | back 16 Since it requires a drop of immersion oil on the slide to provide good resolution. |
front 17 The unaided human eye can distinguish two objects that are at least... | back 17 .1 mm apart |
front 18 The light microscope can distinguish objects that are... | back 18 1,000 times closer |
front 19 Resolving factors are dependent on what 3 factors? | back 19 Angular aperture, refractive index, and wavelength of light |
front 20 The shorter the wavelength of light, the... | back 20 greater the resolution of the objective |
front 21 True or false. Numerical aperture is a pure number | back 21 True |
front 22 Stage and stage clip | back 22 The flat surface the slide will go on. Also, can secure the clip. |
front 23 Mechanical stage knobs | back 23 Knobs that help control the movement of the stage. (right/left and front/back) |
front 24 Coarse focus and fine focus knowledge | back 24 Coarse focus - (larger one) will move the stage up and down. Fine focus - (smaller one) will move the stage smaller amounts |
front 25 Condenser lens | back 25 Helps captures and focuses light from the lamp. |
front 26 Diaphragm | back 26 Allows you to adjust the amount of light passing through the slide by adjusting the lever. |
front 27 Light Source | back 27 Emits light to illuminate the specimen for viewing through ocular lenses. |
front 28 Base and arm | back 28 the bottom of the microscope that sits on the table and the arm is the vertical framework ascending from the base to the back of the microscope. |
front 29 What are biomolecules? | back 29 Macromolecules found in living systems containing five or more carbon atoms linked together to form a chain. |
front 30 What are the 4 key biomolecules organisms are composed of? | back 30 Carbohydrates, lipids, proteins, and nucleic acids |
front 31 What are organic compounds? | back 31 Substances that contain carbon, hydrogen, hydrogen, and oxygen |
front 32 What is a nucleotide? | back 32 The basic structural unit of nucleic acids |
front 33 What are indicators? | back 33 Special chemicals that change color (that is visible to the naked eye) in the presences of specific chemical substance. |
front 34 What do carbohydrates do? | back 34 Provide substrate for cellular respiration which leads to energy production. |
front 35 The basic building blocks for carbs are? | back 35 sugars(monosaccharides) |
front 36 Two monosaccharides | back 36 Disaccharide |
front 37 Multiple monosaccharides linked together | back 37 polysaccharide |
front 38 What does the Benedict's test do? (know the colors it produces) | back 38 It detects reducing sugars. (green=low, orange/yellow=high, and blue=none) |
front 39 What does the Lugol's test do? | back 39 Identifies the presence of starch. (Present=brownish, not present=no color change) |
front 40 What are lipids? | back 40 Compounds that are insoluble in water. Used for energy |
front 41 What is the most common lipid? | back 41 polymer triglyceride |
front 42 What is Sudan VI? | back 42 A fat soluble dye that is water hating. |
front 43 What is hydrophobic? | back 43 Water hating |
front 44 What is hydrophilic? | back 44 Water loving |
front 45 What is a "grease spot"? | back 45 The basis of a very simple test for fats |
front 46 The basic unit of a protein molecule? | back 46 An amino acid |
front 47 What is a bond between two amino acids? | back 47 A peptide bond. (A chain is called a polypeptide) |
front 48 What does a ninhydrin reagent test for? | back 48 Alpha amino acid and proteins contain free amino and acid groups. |
front 49 What is a free amino acid? | back 49 One that is not joined to another amino acid in a chain or ring. |
front 50 What does the Biuret test detect? | back 50 The presences of proteins and short peptide chains of amino acids |
