Across
- 2. one of the lamellar stacks of chlorophyll-containing thylakoids found in plant chloroplasts.
- 3. the transfer of proton across a membrane to create a proton gradient that drives ATP synthesis.
- 5. an organism that eats other plants or animals for energy and nutrients.
- 6. a chemical entity that accepts electrons transferred to it from another compound.
- 8. a process that plants and algae use to turn carbon dioxide from the air into sugar
- 9. requiring only carbon dioxide or carbonates as a source of carbon and a simple inorganic nitrogen compound for metabolic synthesis of organic molecules
- 12. process by which plants use sunlight,water, and carbon dioxide
- 14. minute openings found in the epidermis of leaves, stems and other plant organs.
- 16. give color to plant parts such as ripe tomatoes and autumn leaves.
- 18. evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night.
Down
- 1. the reaction which occurs as the first phase of photosynthesis
- 4. the movement of ions across a semipermeable membrane bound structure, down their electrochemical gradient.
- 7. plastid that contains chlorophyll and in which photosynthesis takes place.
- 10. carries out the absorption of light photons and the transfer of electrons
- 11. substances produced by living organisms that have a color resulting from selective color absorption.
- 13. the process by which plants assimilate carbon from carbon dioxide in the atmosphere to form metabolically active compounds.
- 15. a pigment that gives plants there green color
- 17. any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid
