| Three aspects of cell theory | 1) every living thing is made of cells 2)cells are the basic unit of life 3) All cells are made from other cells |
| Cell Wall | Rigid structure found outside the cell membrane in plants, supports the plant (IN PLANTS ONLY) |
| Cell membrane | Barrier that controls what goes into and out of the cell |
| Nucleus | The control center of the cell |
| Vacuole | Storage place for food, water, wastes, and more |
| Golgi Bodies | Packages and moves proteins |
| Cytoplasm | Gel that fills cells, cushions organelles (the parts inside the cell) |
| Mitochondria | Responsible for creating the energy to run cell processes |
| Lysosome | Break down food particles |
| Endoplasmic reticulum (ER) | Carries material from one part of the cell to another |
| Ribosomes | protein producers |
| Chloroplasts | Turn sunlight into energy (IN PLANTS ONLY) |
| Robert Hooke | First person to describe cells. he looked at cells in 1663 |
| Anton van Leevenhoek | First to see single-celled organisms |
| Light microscope | Focuses light up through specimen, up to 1,000 times magnification |
| Semi-permeable membrane | A membrane that will only allow certain things through it |
| Diffusion | Movement from high concentrations to low concentrations |
| Osmosis | diffusion of water |
| Active transport | Movement of things from low concentration to high concentration (requires the cell to provide energy for this to happen) |
