| Term | Definition |
|---|---|
| Cell Wall | Supports (like an outer skeleton), protects cell, allows materials to go in and out. |
| Cell Membrane | Protects the cell, allows materials to go in and out. |
| Selectively Permeable | Allows only selective items to go in and out. |
| Nucleus | Control center of the cell- Controls everything that the cell does. |
| Chromosomes | Hold the DNA that passes on the traits to offspring |
| Endoplasmic Reticulum | Long tubes that transport materials around the cell. |
| Ribosomes | Make protein which is used to repair cell parts. |
| Mitochondria | Breaks down food, (glucose), to release energy for the cell |
| Vacuole | Stores food and waste for the cell. |
| Chloroplast | Use chlorophyll to capture sun's energy to make molecules of sugar-food, (glucose) |
| cytoplasm | Jelly like substance in the cell that the organelles float in |
| Lysosome | Breaks apart damaged material in the cell and recycles it |
| Nucleoulus | Produce ribosomes |
| Golgi Bodies | Package Proteins and bring them where needed |
| Photosynthesis | When a cell captures the sun's energy with chlorophyll, and uses the energy to make glucose from water and Carbon Dioxide. |
| Glucose | simple sugar molecule that a plant uses to make energy |
| Robert Hooke | Looked at cork- tree bark- slices and saw cells-- named them cells because they looked like an empty room to him. |
| Anton van Leeuwenhoek | Invented the microscope. First time we saw microscopic cells. |
