Across
  1. 4. thin flexible layer made of phospholipids, let's things in and out of cells
  2. 7. movement of materials across the cell membrane using cellular activity
  3. 8. only in plants-captures energy from sunlight to make energy the plant cell can use
  4. 10. large particles are engulfed by the cell which changed shape to accomodate
  5. 13. molecules from an area of high concentration to low concentration
  6. 16. made of one cell (bacteria, amoeba)
  7. 17. a process where the cell membrane uses a channel to allow molecules in and out of the cell easily
  8. 18. only in plant cells rigid outer supporting layer
  9. 19. produces proteins, a key piece of building blocks within the cell
  10. 21. tiny cell structure that carries out specific functions
  11. 22. diffusion of water molecules across a selectively permeable membrane
  12. 24. processes lipids
Down
  1. 1. break down old cell parts and recycle materials to be used again
  2. 2. large particles are released by the cell after changing shape to accomodate
  3. 3. moving materials across the cell membrane without the use of energy
  4. 5. convert food energy into energy the cell can use to live and function
  5. 6. contains the cells genetic material (DNA) controls many of the cells activities
  6. 9. stores water and food that the cell might need also acts as a trash can because it collects unneeded material
  7. 11. filler between the membrane and nucleus, supports all organelles (pool)
  8. 12. some substances can cross the membrane while others cant
  9. 14. made of many cells
  10. 15. recives proteins plus other formed materials from the ER packages them and sends them else where
  11. 20. produces ribosomes
  12. 23. basic unit of structure and function in ALL living things
