  1. 4. first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
  2. 6. the transport of dissolved substances into cells.
  3. 12. energy-carrying biological molecule, which, when broken down, drives cellular activities
  4. 13. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
  5. 15. the main organ of photosynthesis and transpiration in higher plants
  6. 16. process that does not require oxygen
  7. 18. process that requires oxygen
Down
  1. 1. process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches
  2. 2. process that releases energy from food in the presence of oxygen
  3. 3. organelle that is the site of ATP (energy) production
  4. 5. pairs of cells that surround stomata and control their opening and closing.
  5. 7. the form of sugar that circulates in the blood and provides the major source of energy for body tissues.
  6. 8. an organism that makes its own food
  7. 9. a substance or molecule that participates in a chemical reaction
  8. 10. an organ in vascular plants that anchors the plant and enables it to absorb water and minerals from the soil.
  9. 11. the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
  10. 13. green pigmnet in plants the absorbs light energy used to carry out photosynthesis
  11. 14. Produced in muscle cells under anaerobic conditions so that glycolysis can continue.
  12. 17. a substance that forms in a chemical reaction
