Across
  1. 1. a monosaccharide or disaccharide, like glucose and sucrose.
  2. 4. form of energy in sunlight.
  3. 7. short-term energy carrier; temporarily stores energy during photosynthesis.
  4. 8. common name of a plant-like protist, which contains chloroplasts and makes food by photosynthesis.
  5. 11. organic compound that supplies energy to the body, such as sugar and starch.
  6. 14. an individual living thing.
  7. 15. energy-carrying molecule that cells use to power their metabolic processes; provides the cell with an immediate usable form of energy.
  8. 16. mixture of gases that surrounds a planet such as Earth.
  9. 18. fluid-filled space inside a chloroplast where the second stage of photosynthesis (Calvin cycle) occurs.
  10. 19. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis.
  11. 20. plant organ that generally grows down into the soil to absorb water and nutrients from the soil.
  12. 22. large, complex carbohydrate found in foods such as grains and vegetables that the body uses for energy.
  13. 23. tiny pore in the leaf of a plant that can open and close to control transpiration (release of water vapor) and gas exchange with the air.
  14. 26. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis.
  15. 27. structure within the cytoplasm of a cell that is enclosed within a membrane and performs a specific job.
Down
  1. 2. third stage of cellular respiration, which occurs on the inner membrane of mitochondria, requires oxygen, and produces up to 34 molecules of ATP.
  2. 3. membrane in a chloroplast where the light reactions of photosynthesis occur.
  3. 5. first stage of photosynthesis in which light energy from the sun is captured and changed into chemical energy that is stored in ATP and NADPH.
  4. 6. simple sugar that all living things use to store and transport energy.
  5. 9. type of blood vessel that generally carries deoxygenated blood toward the heart.
  6. 10. eukaryotic organism in the protist kingdom.
  7. 12. multicellular, heterotrophic eukaryote with specialized cells that lack cell walls; member of the animal kingdom.
  8. 13. process that occurs when one or more substances, called reactants, is changed into one or more new substances, called products.
  9. 17. the ability to do work.
  10. 19. second stage of photosynthesis in which carbon atoms from carbon dioxide are combined, using the energy in ATP and NADPH, to make glucose.
  11. 21. single-celled prokaryotic organism that is a member of the Bacteria domain.
  12. 24. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis (light reactions) occurs.
  13. 25. smallest particle of a compound that still has that compound’s properties.
