| Cell | The basic unit of structure and function of living things |
| Cell Theory | 1) The cell is the basic unit of structure of all living things 2) All life functions are carried out by cells or parts of cells 3) Cells arise (come) from other living cells |
| Unicellular | Single celled (one-celled) |
| Multicellular | Many celled |
| Virus | Not living because 'not made of cells (even though they contain genetic material) |
| Host cell | The place where viruses reproduce |
| van Leeuwenhoek | Made the first microscope |
| Hooke | Made first *compound* microscope and named cells "cells" |
| Brown | Identified the plant nucleus |
| Schleiden | Discovered that all plants are made of cells |
| Schwann | Discovered that all animals are made of cells |
| Virchow | Stated that all new cells must come from previously existing cells |
| Compound Light Microscope | Microscope most commonly used for cell study |
| Specimen | Material being studied (under microscope) |
| Objective Lens | Lens near specimen |
| Eyepiece Lens | Lens that you put your eye next to |
| Diaphragm | Microcope part that controls amount of light passing through specimen |
| Coarse Adjustment | Used for rough focus |
| Fine Adjustment | Used for fine focus |
| Arm | Used for carrying microscope |
| Slide Clip | Holds slide on microscope stage |
| Staining Techniques | "Color" certain cell parts so they are more easily studied with the compound light microscope |
| Iodine | A common cell stain (that makes some cell parts brown) |
| Methylene Blue | A common cell stain (that makes some cell parts blue) |
| Dissecting Microscope | Allows you to study large specimens that can not be easily seen with the compound light microscope |
| Electron Microscope | A microscope that uses a beam of electrons instead of a beam of light (and magnifies more than 100,000 times) |
| Ultracentrifuge | A tool that spins specimens so fast that they get separated by density |
| Magnify | Enlarge |
| Total magnification | Total amount the image is enlarged (eyepiece lens power x objective lens power) |
| Micrometer | 1/1000 of a millimeter |
| Micron | 1/1000 of a millimeter |
| Microbiologist | A life scientist that studies organisms so tiny that they must be seen under a microscope |
| High Power Objective | The longer objective with the higher magnification power (that you don't use the coarse adjustment with) |
| Low Power Objective | The shorter objective with the lower magnification power (that you shouldn't confuse with the tiny "scanning objective") |
| Nosepiece | The microscope part that holds the objective lenses |
