Across
  1. 2. (A and B); the two major pigments involved in photosynthesis.
  2. 4. _____ bisphosphate (RuBP); an organic substance that is involved in photosynthesis, notably as the principal CO 2 acceptor in plants.
  3. 8. a class of more than 750 naturally occurring pigments synthesized by plants, algae, and photosynthetic bacteria
  4. 11. plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process
  5. 12. the set of compounds that have an intense color and are used in the coloring of other materials
  6. 14. _____ Cycle; the cycle of chemical reactions where the carbon from the carbon cycle is fixed into sugars. It occurs in the chloroplast of the plant cell.
  7. 15. Photosystem _____ (PSI); an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin
  8. 17. the molecules known as hydrocarbons and found in orange and yellow fruits and vegetables, for example, pumpkin, cantaloupe, sweet potatoes, apricots and carrots.
  9. 18. _____ spectrum; an electromagnetic spectrum in which a decrease in intensity of radiation at specific wavelengths or ranges of wavelengths characteristic of an absorbing substance is manifested especially as a pattern of dark lines or bands.
  10. 19. The cells and tissues that support and give structure to organs, glands, or other tissues in the body.
  11. 20. Glyceraldehyde 3-phosphate or G3P is the product of the Calvin cycle
Down
  1. 1. _____ reactions; use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.
  2. 3. Ribulose bisphosphate carboxylase/oxygenase; a key enzyme in photosynthesis catalyzing carbon dioxide fixation.
  3. 5. _____ spectrum; the complete range of all types of radiation that has both electric and magnetic fields and travels in waves.
  4. 6. Photosystem _____ (PSII); a membrane protein supercomplex that executes the initial reaction of photosynthesis in higher plants, algae, and cyanobacteria.
  5. 7. a coenzyme that functions as a universal electron carrier, accepting electrons and hydrogen atoms to form NADPH, or nicotinamide adenine dinucleotide phosphate.
  6. 9. _____ membrane; the site of the light-dependent reactions of photosynthesis with the photosynthetic pigments embedded directly in the membrane
  7. 10. technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase
  8. 12. a quantum of radiant energy with a visible wavelength
  9. 13. the breakdown of any particular substance in presence of light
  10. 16. _____ fixation; the process by which CO2 is incorporated into organic compounds.
