Across
  1. 2. an organelle in which proteins are processed, sorted, or modified
  2. 4. the site for the production of lipids (fats) and hormones; also responsible for detoxification, or breakdown, of toxic chemicals
  3. 6. a place on the lipid bilayer that allows materials to move from one side of the membrane to the other, usually without using any energy
  4. 8. the living material of the cell found within the plasma membrane
  5. 9. units of hereditary data that dictate the activity and structure of the cell
  6. 13. structures in which cellular proteins are assembled
  7. 15. the pumping of molecules across the cell membrane that requires the use of energy
  8. 17. structures on which genetic information in the nucleus is organized
  9. 18. a place on the lipid bilayer that moves materials forcefully from one side of the membrane to the other, requiring energy
  10. 20. the intracellular fluid made of water, dissolved ions, and proteins
  11. 21. the movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached; a type of passive transport
  12. 22. the molecules that make up the flexible membrane that surrounds the contents of the cell
  13. 23. a state in which the number of molecules is equal on both sides of a membrane
Down
  1. 1. attracted to water molecules
  2. 3. the thin layer responsible for separating the internal structures of the cell from its surrounding environment, as well as providing support for the cell; also called the cell membrane
  3. 5. the site for the production of proteins for the cell secretions and cell membrane
  4. 7. the thin layer responsible for separating the internal structures of the cell from the surrounding environment, as well as providing support for the cell; also called the plasma membrane
  5. 10. the most basic unit of life, responsible for carrying out functions of life
  6. 11. repels water moleculesosmosis: the diffusion of water across a semipermeable membrane; a type of passive transport
  7. 12. the type of cell that contains membrane-bound organelles and has a distinct nucleus
  8. 14. reticulum: an internal network of membranes extending throughout the cytoplasm
  9. 16. the type of cell that lacks a nucleus and contains its genetic information in the cytoplasm
  10. 19. the movement of molecules across the cell membrane that does not require the use of energy
