Across
  1. 5. type of plastid located in roots and non-photosynthetic tissues of plants; may make molecules such as fatty acids and many amino acids or may become specialized for bulk storage of starch, lipid, or protein.
  2. 7. group of specialized cells of the same kind that perform the same function.
  3. 8. complex carbohydrate that is a polymer of glucose and that makes up the cell wall of plants.
  4. 13. tough, hydrophobic carbohydrate molecule that stiffens and waterproofs vascular tissues of plants.
  5. 14. membrane in a chloroplast where the light reactions of photosynthesis occur.
  6. 15. water-insoluble organic compound that organisms use to store energy such as fats and oils.
  7. 21. fluid-filled space inside a chloroplast where the second stage of photosynthesis (Calvin cycle) occurs.
  8. 22. Membrane that surrounds the central vacuole and has proteins that control the flow of water into and out of the vacuole.
  9. 23. the ability to do work.
  10. 26. organism that has cells containing a nucleus and other membrane-bound organelles.
  11. 27. structure within the cytoplasm of a cell that is enclosed within a membrane and performs a specific job.
  12. 29. flattened sac of membrane inside a chloroplast where the first stage of photosynthesis (light reactions) occurs.
  13. 30. large sac-like organelle in plant cells that stores substances such as water and helps keep plant tissues rigid.
  14. 32. any substance in food that the body needs.
  15. 33. single-celled prokaryotic organism that is a member of the Bacteria domain.
  16. 34. rigid layer that surrounds the cell membrane in plants, fungi, and bacteria that helps support and protect the cell.
  17. 35. a complex carbohydrate polymer formed from the linkage of many monosaccharide monomers.

  1. 1. group of closely related membrane-bound organelles that carry out many functions; they are responsible for photosynthesis, for the storage of products such as starch, and for the synthesis of many types of molecules that are needed as cellular building blocks.
  2. 2. process in which cells use carbon dioxide, water, and light energy to make oxygen and glucose, an energy-storing sugar
  3. 3. thin coat of phospholipids that surrounds a cell and controls what enters and leaves the cell.
  4. 4. maintain turgor pressure against the cell wall
  5. 6. green pigment in a chloroplast that absorbs light energy during the light reactions of photosynthesis.
  6. 8. basic unit of structure and function of living things.
  7. 9. large, complex carbohydrate found in foods such as grains and vegetables that the body uses for energy.
  8. 10. organic compound made up of amino acids.
  9. 11. largest component of the cytoskeleton; hollow protein cylinder made of alpha and beta tubulin.
  10. 12. structure found in all cells that is the site of protein synthesis.
  11. 16. type of plastid that makes and stores other pigments.
  12. 17. organelle in the cells of plants and algae, that contains chlorophyll and is the site of photosynthesis.
  13. 18. multicellular, heterotrophic eukaryote with specialized cells that lack cell walls; member of the animal kingdom.
  14. 19. double-stranded nucleic acid that stores genetic information; also known as deoxyribonucleic acid.
  15. 20. within the chloroplast, consists of sac-like membranes, known as thylakoid membranes.
  16. 24. watery substance that makes up cytoplasm, and contains other cell structures such as ribosomes.
  17. 25. an atom or group of bonded atoms that has a positive or negative charge.
  18. 28. Most mature plant cells have a __________________ that occupies more than 30% of the cell's volume
  19. 31. a protein that acts as a biological catalyst, increasing the rate of a biochemical reaction.
