Across
  1. 2. Damage to plant cells due to water loss in a hypertonic environment.
  2. 5. A type of endocytosis where the cell "eats" large particles, such as bacteria or food.
  3. 7. The optimal state for a plant cell in a hypotonic solution, where the cell wall prevents bursting, leading to firm support.
  4. 11. Type of fatty acids that increases membrane fluidity
  5. 12. Diffusion of substances across the membrane with the help of transport proteins
  6. 13. A type of endocytosis where the cell "drinks" extracellular fluid and dissolved solutes.
  7. 14. A solution with a lower solute concentration than the cell, causing water to move into the cell.
  8. 15. This lipid acts as a "fluidity buffer" in animal cell membranes
  9. 17. Forms bilayers, main lipid component
  10. 18. The state of a plant cell in an isotonic solution, where there is no net movement of water, and the cell is limp.
  11. 20. The process by which cells release substances to their external environment by fusing vesicles with the plasma membrane.
Down
  1. 1. Passive movement of substances from an area of higher concentration to an area of lower concentration.
  2. 3. The bursting of an animal cell when placed in a hypotonic solution due to excessive water intake.
  3. 4. A solution with the same concentration of solutes as the cell, cell neither loses or gains water
  4. 6. This type of transport requires energy.
  5. 8. The shriveling of an animal cell when placed in a hypertonic solution due to water loss.
  6. 9. Neither plant nor animal cells like to find themselves in this solution!
  7. 10. The passive movement of water across a selectively permeable membrane.
  8. 14. A solution with a lower solute concentration than the cell, causing water to enter the cell.
  9. 16. Cells take in substances from their external environment by engulfing them in a vesicle.
  10. 19. Greatly facilitates the rapid movement of water across the cell membrane.
