Across
  1. 4. double-layered sheet that forms the core of nearly all cell membranes
  2. 8. process by which a cell releases large amounts of material
  3. 10. small particle in the cell on which proteins are assembled
  4. 14. separate roles for each type of cell in multicellular organisms
  5. 16. internal membrane system in cells in which components of the cell membrane are assembled & some proteins modified
  6. 19. organism whose cell contains nuclei
  7. 20. small, dense region within most nuclei in which the assembly of ribosomes begin
  8. 21. inside the cell membrane other than the nucleus
  9. 22. group of similar cells that perform a particular function
  10. 24. specialized structure that performs important cellular functions within a eukaryotic cell
  11. 28. energy-requiring process that moves material across a cell membrane against a concentration difference
  12. 32. group of organs that work together to perform a specific function
  13. 33. organelle found in cells of plants & some other organisms that uses energy from sunlight to make energy-rich food molecules by photosynthesis
  14. 34. threadlike structure within the nucleus containing the genetic information that is passed from 1 generation of cells to the next
  15. 36. large structure in cells that contains the cell’s DNA & controls the cell’s activities
  16. 37. group of tissues that work together to perform closely related functions
Down
  1. 1. process in which extensions of cytoplasm surround & engulf large particles & tale the, into the cell
  2. 2. strong layer around the cell membrane in plants, algae, & some bacteria
  3. 3. stack of membranes in the cell in which enzymes attach carbohydrates & lipids to proteins
  4. 5. long, thin fibers that functions in the movement & support of the cell
  5. 6. process by which a cell takes material into the cell by infolding the cell membrane
  6. 7. basic unit of all forms of life
  7. 9. property of biological membranes that allows only certain substances to pass through them
  8. 11. thin, flexible barrier around a cell
  9. 12. hollow tube of protein that maintains cell shape & can also serve as a “track” along which organelles are moved
  10. 13. process by which molecules tend to move from an area where they are more concentrated to an area where they are less concentrated
  11. 15. movement of specific molecules across cell membranes through protein channels
  12. 17. the mass of solute in a give volume in solution
  13. 18. cell organelle that stores materials such as water, salts, proteins, & carbohydrates
  14. 23. cell organelle that releases energy from stored food molecules
  15. 25. network of protein filaments within some cells that helps the cell maintain its shape and are involved in many forms of cell movement
  16. 26. idea that all living things are composed of cells
  17. 27. single-celled microorganism that lacks a nucleus
  18. 29. envelope double-membrane layer that surrounds the nucleus of a cell
  19. 30. cell organelle filled with enzymes need to break down certain materials in a cell
  20. 31. granular material visible within the nucleus
  21. 35. diffusion of water through a selectively permeable membrane
