| Term | Definition |
|---|---|
| Organization | the orderly structure of cells in an organism |
| Cell | the basic units of living organisms |
| Compound Light Microscope | use a series of lenses to magnify objects in steps (can magnify up to 1500 times) |
| Cell Theory | 3 main ideas: 1. All organisms are composed of one or more cells. 2. The cell is the basic unit of structure and organization of organisms. 3. All cells come from preexisting cells. |
| Electron Microscope | uses a bean of electrons instead of light to magnify structure up to 500,000 times their actual size allowing scientists to see structures within a cell |
| Organelle | small specialized structures |
| Prokaryote | unicellular organisms (bacteria) do not have membrane-bound organelles |
| Eukaryote | multicellular organisms that contain membrane-bound organelles |
| Nucleus | the central memberane-bound organelle that manages or controls cellular functions |
| Ion | an atom or group of atoms with a positive or negative electrical charge |
| Plasma Membrane | the flexibly boundary between the cell and its environment which allows steady supply of nutrients to come into the cell no matter the external conditions |
| Selective Permeability | a process in which a membrane allows some molecules to pass through while keeping others out |
| Phospholipid | contains a glycerol backbone, two fatty acid chains, and a phosphate group |
| Fluid Mosaic Model | the model of the plasma membrane |
| Transport Protein | moves needed substances or waste materials through the plasma membrane |
