Across
  1. 4. A type of channel protein that allow water to move in and out of cells
  2. 6. Molecule used to transfer energy in the cell (involved in phophorylation)
  3. 7. Organelles that make ATP in eukaryotic cells
  4. 10. A molecule, like an enzyme, that lowers activation energy
  5. 11. Animal cells need this type of 'tonicity' so they do not explode or shrivel
  6. 13. Viruses attach to these molecules that are embedded in the cell membrane
  7. 14. Site of protein synthesis in bacteria and eukaryotic cells
  8. 16. Type of energy associated with movement of molecules
  9. 18. A protein that has a carbohydrate attached to it (used for recognizing different cells)
  10. 20. Green pigment in plant cells, used in photosynthesis
  11. 21. Type of vacuole used to remove water from paramecium cells
Down
  1. 1. Process of cells eating large amounts of material at once (a form of bulk transport)
  2. 2. This molecule carries information from DNA in the nucleus to ribosomes in the cytoplasm
  3. 3. Membrane ____________ describes how the cell membrane a + and - charge outside and inside the cell
  4. 5. Phospholipids and these molecules are the major parts of the cell membrane
  5. 6. Reactions that build up or make larger molecules
  6. 8. Organelle that is used for digestion within the cell
  7. 9. An amphipathic molecule with a polar head and non polar tail
  8. 12. Means 'before the nucleus' and these are bacterial cells like E. coli
  9. 15. Organelle used for storage in both plant and animal cells
  10. 17. Region in bacteria that has DNA and protein
  11. 19. Diffusion and osmosis are examples of this type of transport (requires no energy)
