Across
  1. 2. structure in an animal cell that helps to organize cell division
  2. 4. An organelle containing digestive enzymes
  3. 5. encloses the cell, regulates the passage of materials into and out of the cell; found in all cells
  4. 9. Having a higher concentration of solute than another solution.
  5. 10. A rigid layer of nonliving material that surrounds the cells of plants and some prokaryotes
  6. 16. Powerhouse of the cell, organelle that is the site of ATP (energy) production
  7. 19. contains a cell wall, chloroplast and large vacuole
  8. 21. An organelle found in plant and algae cells where photosynthesis occurs
  9. 25. process by which a cell takes material into the cell by infolding of the cell membrane
  10. 26. smallest unit of life
  11. 27. cell that does not have a nucleus or other membrane-bound organelles.
  12. 28. the movement of substances across a cell membrane without the use of energy by the cell
  13. 29. idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
Down
  1. 1. The transportation system of the cell. It moves materials around the cell
  2. 3. process of diffusion in which molecules pass across the membrane through cell membrane channels
  3. 6. A sac inside a cell that acts as a storage area
  4. 7. Having a lower concentration of solute than another solution
  5. 8. stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
  6. 11. does not have a cell wall or chloroplast and a small vacuole
  7. 12. the movement of materials through a cell membrane using energy
  8. 13. cell that has a nucleus and other membrane-bound organelles
  9. 14. example of a prokaryote
  10. 15. when the concentration of two solutions is the same
  11. 17. A jellylike fluid inside the cell in which the organelles are suspended, found in all cells
  12. 18. Found inside the nucleus and produces ribosomes
  13. 20. Makes proteins, found in all cells
  14. 22. Diffusion of water through a selectively permeable membrane
  15. 23. movement of a solute from an area of high concentration to an area of low concentration
  16. 24. a process by which the contents of a cell vacuole are released to the exterior through fusion of the vacuole membrane with the cell membrane.
