cells and diffusion
| Term | Definition |
|---|---|
| Diffusion | Diffusion is the natural movement of particles from an area of higher concentration to an area of lower concentration, due to random molecular motion |
| Osmosis | movement of water molecules from high concentration of water to low concentration |
| Permeable | allows any molecules to diffuse across membrane |
| Semi permeable | allows certain molecules to diffuse across membrane |
| non permeable | allows no molecules to diffuse across membrane |
| nucleus | controls all activities of the cell growth and reproduction |
| cell membrane | allows certain molecules to go in or out of the cell/molecules |
| cell wall | supports and protects the cell down allow molecules in or out |
| chromosomes | proteins that contains DNA which has coded information for making molecules |
| RER | produces and stores proteins |
| SER | produces and stores fats and oils |
| Golgi Bodies | modifies and packages proteins from rough ER with enzymes |
| Ribosomes | helps Rough ER make proteins is attached to rough ER |
| Centrioles | helps with cell division |
| mitochondria | converts sugar into energy for the cell |
| cytoplasms | fluid in the cell allows organelles to move around |
| vacuoles | stores water minerals and vitamins |
| lysomes | breaks down food invading bacteria |
| chloroplasts | uses sunlight to make it own food |
