Across
  1. 4. The movement of the molecules across the cell membrane is assisted by specific proteins in the membrane
  2. 5. Doesn’t have Concentration Gradient because all concentrations are equal
  3. 6. The pressure that water molecules exert against the cell wall
  4. 7. The process used for molecules that cannot readily diffuse through cell membranes, even when there is a concentration gradient across the membrane
  5. 8. When the concentrations of solutes outside and inside the cell are equal. Water diffuses into and out of the cell at equal rates, so there is no net movement of water
  6. 10. Organelles that remove water
  7. 11. The process by which cells ingest external fluid, macromolecules, and large particles, including other cells.
  8. 13. One of the examples of active transport in animal cells involves a carrier protein
  9. 17. When the concentration of solute molecules outside is lower than the concentration in the cell, and when water diffuses INTO the cell
  10. 18. The process by which a substance is released from the cell through a vesicle that transports the substance to the cell surface and then fuses the membrane to let the substance out of the cell
  11. 19. The movement of molecules from an area of higher to an area of lower concentration
  12. 20. Also known for when water leaves the cells through osmosis
Down
  1. 1. The movement of large particles or whole cells
  2. 2. When the concentration of solute molecules outside the cell is higher than the concentration in the cell, and when water diffuses OUT OF the cell
  3. 3. The difference in the concentration of molecules across a distance
  4. 9. Involves the transport of solutes or fluids
  5. 12. Diffusion across a membrane
  6. 14. In many cases, cells have to move materials from an area of lower concentration to and area of higher concentration
  7. 15. Diffusion of water (in a cell)
  8. 16. The bursting of cells
