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 |

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 |
