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. |
