| Vocab Word | Answer (from textbook) | Anchor/Helper Phrase |
|---|---|---|
| Robert Hooke | Looked at cork under a microscope and came up with the name "cell" | HooKe, corK (hard K sound) |
| Anton von Leeuwenhoek | First person to describe living cells | Leeuwenhoek = LIVINGhoek (first to see living cells) |

| Theodor Schwann | Scientist who determined that all animals are made of cells | Scwann = Swan (animal) |
| Rudolph Virchow | Scientist who is credited with the discovery that all cells come from the reproduction of pre-existing cells | actually stole the work of another scientist and got all the credit |
| cell theory | the theory that explains how all life is based off of cells | 1. All livings things = cells; 2. cells = structure and function; 3. cell come from pre-existing cells |
| compound light microscope | a microscope that uses multiple lens and a light source to magnify specimens | compound = more than one lens |
| total magnification | eyepiece magnification x objective lens magnification | The eyepiece is always x10 (so just multiply the objective lens x 10) |
| prokaryote | unicellular organism that lacks a nucleus | example: bacteria (NOT plants) |
| eukaryote | organism whose cells contain a nucleus | example: plants, animals, fungi |
| nucleus | the structure in a eukaryotic cell that contains the cell's DNA | PROkaryotes have NO _____ |
| cell wall | strong, supporting layer around the cell membrane in some cells | found in plants, fungi, and bacteria, but NOT animals |
| cytoplasm | all cellular contents outside the nucleus | the liquid inside a cell |
| organelles | specialized structure that performs important cellular functions within a cell | the "organs" of the cell |
