Across
  1. 3. mixture of gases that surrounds a planet such as Earth
  2. 5. diffusion of water molecules across a membrane
  3. 9. specialized tissue inside plant leaves where photosynthesis takes place
  4. 10. organic molecules, such as glucose, that organisms use for chemical energy
  5. 12. all the living things in a given area together with the physical and chemical factors of the nonliving environment
  6. 13. release of water vapor into the atmosphere from stomata in the leaves of plants
  7. 14. outer layer of skin that consists mainly of epithelial cells and lacks nerve endings and blood vessels
  8. 16. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar
  9. 19. chemical element such as calcium or potassium that is needed in relatively small amounts for proper body functioning
  10. 22. chemical reaction that occurs inside the cells of living things
  11. 24. simple sugar that all living things use to store and transport energy
Down
  1. 1. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis
  2. 2. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis
  3. 4. type of vascular tissue in a plant that transports food from photosynthetic cells to other parts of the plant
  4. 6. 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
  5. 7. basic unit of structure and function of living things
  6. 8. a group of organisms that can mate with one another to produce fertile offspring
  7. 11. organic compound that supplies energy to the body, such as sugar and starch
  8. 12. the change in a substance from a liquid to a gas by the addition of energy
  9. 15. the ability to do work
  10. 17. waxy, waterproof substance produced by epidermal cells of leaves, shoots, and other above-ground parts of plants to prevent damage and loss of water by evaporation
  11. 18. type of vascular tissue in a plant that transports water and dissolved nutrients from roots to stems and leaves
  12. 20. bean-shaped schlerenchymal cell in the epidermis; swells and shrinks by osmosis to open and close stomata
  13. 21. type of blood vessel that generally carries deoxygenated blood toward the heart
  14. 23. group of specialized cells of the same kind that perform the same function
