Across
- 4. a biochemical pathway of photosynthesis in which carbon dioxide is converted into glucose using ATP
- 5. an organism that produces its own nutrients from inorganic substances or from the environment instead of consuming other organisms
- 7. stacks of thylakoids in a chloroplast
- 12. an organelle found in plant and algae cells where photosynthesis occurs
- 13. an organism that obtains organic food molecules by eating other organisms or their byproducts and that cannot synthesize organic compounds from inorganic materials
- 14. a substance that gives another substance or a mixture its color
- 15. in plants, the solution that surrounds the thylakoids in a chloroplast
Down
- 1. in the thylakoid membranes of chloroplasts, a cluster of chlorophyll and other pigment molecules that harvest light energy for the light reactions of photosynthesis
- 2. a series of molecules, found in the inner membranes of mitochondria and chloroplasts, through which electrons pass in a process that causes protons to build up on one side of the membrane
- 3. a water-conserving, carbon-fixing process; CAM plants take in carbon at night and fix it into various organic compounds and release it during the day
- 6. the initial reaction in photosynthesis, which is triggered by the absorption of light by photosystems I and II and includes the passage of electrons along the electron transport chains
- 8. the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen
- 9. a membrane system found within chloroplasts that contains the components for photosynthesis
- 10. a green pigment that is present in most plant and algae cells and some bacteria, that gives plants their characteristic green color, and that absorbs light to provide energy for photosynthesis
- 11. one of many openings in a leaf or a stem of a plant that enable gas exchange to occur (plural, stomata)
- 12. orange pigment that is present mostly in plants and aids in photosynthesis
