Across
  1. 3. An aquatic organism commonly used in required practicals to investigate the effect of light intensity on photosynthesis rate.
  2. 4. A large carbohydrate molecule synthesized in animals to store glucose for energy.
  3. 6. The amount of extra oxygen required after vigorous exercise to react with and remove accumulated lactic acid
  4. 8. The product of the incomplete breakdown of glucose during anaerobic respiration in animal muscle cells.
  5. 10. The state of an enzyme at high temperatures when its active site changes shape and can no longer bind to its substrate.
  6. 11. A type of chemical reaction like cellular respiration that continuously occurs in living cells to release energy.
  7. 12. The plant tissue that transports water and dissolved mineral ions up from the roots to the leaves.
  8. 13. A chemical solution used to test a leaf for the presence of starch to prove that photosynthesis has taken place.
  9. 15. Organisms like plants that can make their own food using light, water, and carbon dioxide.
  10. 16. The sum of all the chemical reactions continually occurring in a cell or the body of an organism.
  11. 17. A chemical reaction such as photosynthesis in which energy is transferred from the environment to the chloroplasts by light.
  12. 18. Lipid molecules formed from one glycerol and three fatty acids used for energy storage and insulation in animals.
  13. 19. Tiny pores on a leaf through which carbon dioxide diffuses into the plant and oxygen diffuses out.
Down
  1. 1. An insoluble molecule used by plants to store excess glucose in their stems, leaves, and roots without affecting osmosis.
  2. 2. The term given to anaerobic respiration in yeast cells, which produces ethanol and carbon dioxide.
  3. 5. A type of environmental factor that is in shortest supply and restricts the overall rate of photosynthesis.
  4. 7. The green pigment in chloroplasts that absorbs light energy required for photosynthesis to take place.
  5. 9. A complex carbohydrate made from glucose that strengthens plant cell walls.
  6. 14. A chemical compound formed in animals by the breakdown of excess proteins which is then excreted.
  7. 16. The cellular organelles where most of the reactions for aerobic respiration take place.
