Across
  1. 1. the process of moving ions (e.g. protons) to the other side of a biological membrane, and as a result, an electrochemical gradient is generated
  2. 3. a collection of proteins bound to the inner mitochondrial membrane and organic molecules, which electrons pass through in a series of redox reactions, and release energy.
  3. 5. When a photon raises a chlorophyll electron to a higher energy level, that energy, and ultimately an electron, has to go somewhere. That somewhere, ideally for the photosynthesizing organism, is known as the Primary Electron Acceptor
  4. 6. each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, and arranged in stacks or grana.
  5. 9. initial carbon fixation takes place in mesophyll cells and the Calvin cycle takes place in bundle-sheath cells.
  6. 10. specialized pores or openings present in the epidermis of plant cells
  7. 12. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  8. 15. an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.
  9. 16. a biochemical mechanism in plants by which chlorophyll absorbs light energy for photosynthesis. There are two such mechanisms ( photosystems I and II ) involving different chlorophyll-protein complexes.
  10. 17. The series of biochemical reactions in photosynthesis that require light energy that is captured by light-absorbing pigments (such as chlorophyll) to be converted into chemical energy in the form of ATP and NADPH.
Down
  1. 1. adapted in plants to perform photosynthesis under stress
  2. 2. a fat-soluble pigment found naturally in plants
  3. 4. the process by which plants fix atmospheric carbon to form organic compounds
  4. 7. are accessory pigments that are typically yellow, red and orange
  5. 8. a stack of coin-shaped thylakoids in the chloroplasts of plant cells
  6. 9. an essential part of the photosynthetic process in plants, algae, and some bacteria
  7. 10. the supportive tissue of an epithelial organ, tumor, gonad, etc., consisting of connective tissues and blood vessels.
  8. 11. an organism deriving its nutritional requirements from complex organic substances.
  9. 13. the set of compounds that have an intense colour and are used in the colouring of other materials
  10. 14. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
