Across
  1. 1. location within the plant where photosynthesis occurs
  2. 6. morphologically distinct leaves that are usually smaller, thicker, having larger palisade cells, typically found in parts of the plant with certain light availability (two words)
  3. 9. the microbe-rich environment immediately surrounding plant roots, which includes the root cortex
  4. 10. the location where the dark reactions occur
  5. 12. Plants that utilize CAM photosynthesis separate CO2 fixation and the dark reactions _______________ so as to concentrate CO2 at rubisco
  6. 13. the intensity of light is measured in photon micromoles per meter per second, also referred to as this
  7. 15. a plant sexual system in which both male and females occur on the same plant, separately
  8. 19. this enzyme is crucial for photosynthesis, being responsible for “fixation” (attaching) of atmospheric CO2 to another molecule
  9. 20. variation in the phenotype of a single genotype caused by environmental conditions (two words)

  1. 2. plants in this family form symbiotic associates with nitrogen fixing bacteria in structures called “nodules” in their roots (common name of family)
  2. 3. Plants that utilize C4 photosynthesis separate CO2 fixation and the dark reactions _______________ so as to concentration CO2 at rubisco
  3. 4. in plant life cycle, the products of meiosis
  4. 5. one of the products of the light reactions that carries high energy electrons for use in the dark reactions
  5. 7. the pores on a plant that allow for gas exchange
  6. 8. in C3 plants, the first stable molecule produced after carbon fixation has ________ carbons.
  7. 11. Light ___________ point refers to the amount of light energy required to fix sufficient CO2 to make up for CO2 lost due to respiration
  8. 14. the plant cell wall is composed of a considerable amount of this polysaccharide
  9. 16. the lower side of a leaf where stomata are found
  10. 17. in alternation of generations, the generation that is diploid and produces spores
  11. 18. the upper side of a leaf (facing the sun), and where photosynthetic activity is highest
  12. 21. the number of hours of light and darkness in a 24-hour period
