Cells and Diffusion
| Term | Definition |
|---|---|
| Nucleus | Found in both animal and plant cells - controls all the activities of the cell |
| Vacuoles | Found in both animal and plant cells - stores water, minerals and vitamins; much bigger in plant cells |
| Cell Membrane | Found in both animal and plant cells - allows certain molecules to go in and out of the cell ; molecules diffuse in or out of the cell ; made up of a phosphorus layers interconnected |
| Cell Wall | Found in plant cells - does not allow molecules in or out; supports and protects the cell |
| Chromosomes | Found in both animal and plant cells - proteins that contain DNA which has coded information for making molecules |
| Rough Endoplasmic Reticulum | Found in both animal and plant cells - produces and stores proteins |
| Smooth Endoplasmic Reticulum | Found in both animal and plant cells - produces and stores fats and oils |
| Golgi Bodies | Found in both animal and plant cells - modifies and packages proteins from rough endoplasmic reticulum with enzymes |
| Ribosomes | Found in both animal and plant cells - helps rough endoplasmic reticulum make proteins ; is attached to the rough endoplasmic reticulum |
| Centrioles | Found in animal cells - helps with cell division (mitosis) ; spindle fibres come from here |
| Mitochondria | Found in both animal and plant cells - converts sugar into energy |
| Cytoplasm | Found in both animal and plant cells - fluid in cells ; allows organelles to move around |
| Centrioles | Found in animal cells - helps with cell division (mitosis) ; spindle fibres come from here |
| Lysosomes | Found in animal cells - breaks down food, invading bacteria and old/damaged organelles |
| Chloroplasts | Found in plant cells - uses sunlight to make its own food ; photosynthesis ( CO2 + H2O + light --> C6H12O6 + O2) |
| Mitochondria | Found in both animal and plant cells - converts sugar into energy |
| Osmosis | the movement of molecules from areas of low concentration to high concentration |
| Cytoplasm | Found in both animal and plant cells - fluid in cells ; allows organelles to move around |
| Lysosomes | Found in animal cells - breaks down food, invading bacteria and old/damaged organelles |
| Chloroplasts | Found in plant cells - uses sunlight to make its own food ; photosynthesis ( CO2 + H2O + light --> C6H12O6 + O2) |
| Diffusion | the movement of molecules from areas of high concentration to low concentration |
| Osmosis | the movement of water molecules from high concentration to low concentration |
