Chapter 6 Biology Crossword

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

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
