Across
- 1. the material within a chloroplast that surrounds the thylakoids.
- 3. a flattened, membrane-bound sac inside a chloroplast where the light-dependent phase of photosynthesis takes place.
- 6. the process whereby plants, algae, and some bacteria form simple sugars from carbon dioxide and water in the presence of light and chlorophyll.
- 7. the first phase of cellular respiration, which glucose is broken down into pyruvate.
- 9. respiration the process by which cells break down glucose or other nutrients to produce usable energy.
- 10. acid cycle the second phase of aerobic cellular respiration in which pyruvate reacts with enzymes to produce acetyl CoA carbon dioxide, hydrogen ions, ATP, and electrons; called the Krebs cycle.
- 11. phase the portion of photosynthesis that does not require light energy in order to proceed. But the light-independent phase does require the products of the light-dependent phase; therefore, neither phase occurs during darkness. AKA Clavin cycle.
- 12. phase the portion of photosynthesis that requires light energy.
Down
- 2. process any chemical process that does not require oxygen.
- 4. the anaerobic breakdown of sugars to pyruvate and then to either lactic acid or carbon dioxide.
- 5. the green pigment of plant cells that is necessary for photosynthesis.
- 8. cycle The portion of photosynthesis that uses energy captured during the light-dependent phase to convert carbon dioxide and water into sugars; also known as the light-independent phase.
