| Cell | Smallest unit of any living organism. |
| An example of a 1-celled organism. | Amoeba |
| An example of a many-celled organism. | Human |
| Two organelles found in plant & not in animal cells. | Cell wall & chloroplast. |
| Function of the nucleus | Controls all cell activities & contains genes. |
| Function of the cell membrane | Allows nutrients to enter & waste to leave the cell. |
| Function of the cell wall | Gives shape to plant cells. |
| Function of cytoplasm | Holds organelles in place & moves things around the cell. |
| Function of chloroplast | Holds chlorophyll to carry out photosynthesis |
| Function of mitochondria | Uses oxygen to release energy in nutrients |
| Why do plant cells need chloroplasts and animal cells do not? | Plants need to carry out photosynthesis to make food. |
| Cell division | Process that cells use to reproduce so there are many of them in a body. |
| Nutrients taken in by plant cells are used for this. | energy |
| DNA or genetic information is found in this organelle. | nucleus |
| Field of vision | Circle of light that shows the amount of the specimen viewed under the microscope. |
| Magnify | To look larger |
| How do you safely carry a microscope? | Using 2 hands - 1 on the arm & 1 under the base. |
| How do you safely unplug a microscope? | Pull the plug, not the wire. |
| Specimen | Object mounted on a slide. |
| Slide | Object to mount a specimen on. |
| Focus | Make clearer with the wheel adjustment. |
| This happens to the to the field of vision as the microscope power increases. | It decreases |
| The amount of the specimen you see when you switch to a higher power. | Less |
| As the microscope power gets larger this is what happens to to how the specimen looks. | It looks larger. |
| The direction specimens are in as compared to how they are put on the slide. | Upside down. |
| How do objects under the microscope appear to move as compared to how you move the slide? | The opposite way. |
| Microscopic | Too small to be seen with the unaided eye. |
| Function of the lens (objective) | Lens closest to the specimen that magnifies. |
| Wheel adjustment | Used to focus |
| Stage | Holds the slide |
| Barrel | Holds the lenses |
| Revolving eyepiece | Changes the power of the objective. |
| Stage opening | Lets the light shine onto the object. |
| Stage clips | Holds the slide in place on the stage. |
| Eyepiece | To look through to see the specimen. |
| General shape of a plant cell | Squarish |
| General shape of an animal cell. | Roundish |
| Purpose of a stain, such as methylene blue. | Show more detail of the specimen. |
