Photosynthesis Vocab
| Term | Definition |
|---|---|
| Photosynthesis | The process by which plants convert sunlight, water, and carbon dioxide into food energy. |
| Cellular Resperation | The chemical process that generates most of the energy in the cell. |
| Chloroplast | An elongated cell organelle containing chlorophyll where photosynthesis takes place. |
| Chlorophyll | A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into sugar and oxygen. |
| Glucose | The food for the plant. |
| Mitochondria | Rod-shaped organelles with a double membrane which converts the energy stored in glucose into ATP for the cell. |
| Photosynthesis Equation | H2O + CO2 + light --> O2 + C6H12O6 |
| Respiration Equation | O2 + C6H1206 --> H20 + CO2 + ATP |
| Carbon Dioxide | Enters the plant through small openings on the underside of the leaves called stomata. Once in the leaves, the water and carbon dioxide move into the chloroplasts. |
| Diffusion | The movement of molecules from an area in which they are highly concentrated to an area in which they are less concentrated. |
| Osmosis | The diffusion of water across a selectively permeable membrane. |
| Active Transport | The movement of materials through a cell membrane using cellular energy. |
