Across
  1. 2. type of transport that moves materials from low to high concentration and requires energy
  2. 7. cell part found only in plants and green algae; site of photosynthesis
  3. 9. cell part in eukaryote cells that produces energy during cellular respiration
  4. 11. diffusion of water from high to low amount/concentration
  5. 12. division of the entire cell into two new identical daughter cells after mitosis
  6. 14. outer boundary around cells that controls what enters and exits in order to maintain homeostasis
  7. 16. size of prokaryotes
  8. 18. when prokaryote cells split in half, but do not undergo mitosis
  9. 19. structure in Euglena that detects light for photosynthesis
  10. 22. this happens when a cell is placed in a solution that has a lower percent of water than the cell
  11. 24. the ability to maintain stable internal conditions
  12. 25. the main component of the cell membrane; has fatty acids that create a hydrophobic boundary around the cell
  13. 28. type of chromosome eukaryotes have
  14. 29. energy molecule created by the mitochondria and required during active transport
  15. 31. the only living thing that is a prokaryote cell
  16. 32. the part of interphase when the DNA is doubled
  17. 33. single-celled eukaryotes
  18. 34. found in the nucleus of eukaryotes; and free floating in the cytoplasm in prokaryotes
  19. 36. structure in Paramecium that controls water balance
  20. 37. the part of the cell cycle where the cell spends most of its time; where everything is doubled in preparation for cell division
Down
  1. 1. protective, outer structure around plant cells and some bacteria
  2. 3. process that occurs in eukaryotic cells when DNA coils into chromosomes and moves to separate sides of the cell so that each new cell will be identical when it divides
  3. 4. one or two long whip-like structures that produce movement in protists
  4. 5. many small hair-like structures used for movement in protists
  5. 6. type of chromosome prokaryotes have
  6. 8. cell part in all cells that produces proteins
  7. 10. contains DNA in eukaryote cells
  8. 13. large storage organelle in plants
  9. 15. this happens when a cell is placed in a solution that has a higher percent of water than the cell
  10. 17. a cell that has a nucleus and many compartments
  11. 20. an organism's movement toward light
  12. 21. the act of doubling the amount of DNA during interphase
  13. 23. type of random transport that does not require energy
  14. 26. a cell that has no nucleus or compartments
  15. 27. passive transport of any material from high to low amount/concentration
  16. 30. the process of turning on or activating certain segments of DNA (genes) and creating specialized cells
  17. 32. undifferentiated cells that can divide and create new cells
  18. 35. false feet in amoeba; produced by moving cytoplasm in one direction
