Cell Activities
| Term | Definition |
|---|---|
| Osmosis | diffusion of water across a membrane |
| Semipermeable | only some substances can pass through |
| Photosynthesis | process where plants capture energy from the sun and change it into food |
| Chlorophyll | pigment that absorbs light and gives plants their green color + absorbs sunlight for energy |
| Endocytosis | process where a cell absorbs a particle |
| Exocytosis | process where a particle "exits" a cell |
| Cellular respiration | process by which cells use oxygen to produce energy from food |
| Fermentation | breakdown of food |
| Diffusion | movement of material from areas of high concentration (crowded) to low concentration (spread out) |
| Chloroplast | organelle that contains chlorophyll |
| Fermentation | the breakdown of food without the use of oxygen |
| Active transport | movement of substances across a membrane + REQUIRES ENERGY |
| Passive transport | movement of substances across a membrane + DOES NOT REQUIRE ENERGY |
| Element "C" | Carbon |
| Element "O" | Oxygen |
| Element "H" | Hydrogen |
| CO2 | Carbon dioxide |
| H2O | Water |
| C6 H12 O6 | Glucose (sugar) |
| O2 | Oxygen |
| Important organelle for photosynthesis | Chloroplast |
| Important organelle for respiration | Mitochondria |
