|---|---|
| cell membrane | controls what enters and exits a cell |
| cell wall | provide protection in plants, found outside cell membrane |
| mitochondria | takes energy from food and converts into ATP which is usable by our bodies |
| centrioles | used during cell division in animal cells only |
| lysosomes | break down materials in the cell and digest dead or bad materials |
| chloroplasts | convert energy from the sun into food through photosynthesis in plants |
| vacuoles | store waste, water, salts, nutrients, large one in plants, many small ones in animals |
| ribosomes | site of protein synthesis |
| diffusion | moving substances from a high to low concentration without energy |
| osmosis | movement of water in a cell |
| endocytosis | requires ATP, takes items into a cell |
| exocytosis | requires ATP, takes items out of a cell |
| pinocytosis | requires ATP and a vesicle, moves items into a cell |
| phagocytosis | requires ATP, engulfs material |
| benedict's solution | used to indicate for glucose, requires heat, turns orange |

| diaphragm | controls flow of light into the microscope |
| objectives | magnify the object on the slide, multiply the eye piece x objecstives to get the magnification |
| diffusion through a membrane lab | created a cell and monitor how size limits what can enter and exit a cell, recommend looking over state lab questions |
| What are the 3 parts of the cell theory | cells come from pre-existing cells, cells have structure and function, all living things are made of cells |
| What is the exception to the cell theory | viruses |
| what is the procedure for staining a slide | keep cover slip on, add stain on one side of slip and paper towel on the other side to draw the stain through |
