Diffusion
| Question | Answer |
|---|---|
| Active Transport | The movement of materials across a membrane from LOWER to HIGHER concentration, using ATP |
| ATP | Produced in the MITOCHONDRIA, it is a molecule that is the source of an organism's ENERGY |
| Cell Membrane | Thin layer of lipids and proteins that surround a cell and controls the passage of materials in and out (AKA PLASMA MEMBRANE) |
| Diffusion | Passive movement of materials across a membrane from HIGH concentration to LOW concentration, requiring NO ENERGY |
| Glucose | The most common sugar used by living organisms. It is needed for cellular respiration to occur |
| Indicator | A chemical that causes an observable change that shows the presence of another substance |
| Osmosis | Diffusion of WATER across a membrane from HIGH concentration to LOW concentration, requiring NO energy |
| Passive Transport | Movement of substances across a membrane from high to low concentration WITHOUT using ENERGY |
| Semi-Permeable | Ability of a membrane to allow SOME but NOT ALL substance to pass through |
| Stain | Any chemical that makes the parts of the specimen under the microscope more visible |
| Starch | A large carbohydrate composed of simple sugars involved in energy storage in an organism |
