  1. 2. Dioxide During photosynthesis, plants take in carbon dioxide (CO2) from the air and soil. The carbon dioxide is reduced, meaning it gains electrons. The carbon dioxide turns into glucose.
  2. 5. Transports the soluble organic compounds made during photosynthesis.
  3. 6. A green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
  4. 8. Stomata allow a plant to take in carbon dioxide.
  5. 11. Cell A plant cell is a eukaryotic cell enclosed by a cell wall, containing a membrane-bound nucleus and other cell organelles.
  6. 12. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.
  7. 16. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
  8. 17. six carbon dioxide molecules and six water molecules.
  9. 18. The sun gives off a mix of mostly red and blue light, these are the colors that chlorophyll absorbs best. Without sunlight, plants would not be able to live and there would be no oxygen for people to breathe.

  1. 1. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  2. 3. Cellular respiration converts oxygen and glucose into water and carbon dioxide.
  3. 4. The main function of xylem is to transport water upwards from the roots to the rest of the plant.
  4. 7. Any of a class of small organelles, such as chloroplasts, in the cytoplasm of plant cells, containing pigment or food.
  5. 9. During photosynthesis, plants take in water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons. This transforms the water into oxygen.
  6. 10. A green plant is a plant having main pigment chlorophyll in it with which it is capable to perform the main function of photosynthesis to prepare its own food.
  7. 12. a sugar molecule and six oxygen molecules. C6H12O6 + 6O2
  8. 13. Oxygen is produced in photosynthesis from the water that is oxidized.
  9. 14. Light The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm).
  10. 15. Cells Regulate the entry of materials necessary for photosynthesis
