Across
- 2. cube-like structure
- 5. water solutes are forced through a membrane by fluid, or hydrostatic, pressure
- 8. allows communication between neighboring cells
- 10. 1 layer
- 12. transports lipid-insoluble and large substances
- 14. transparent barrier for cell contents, fluid mosaic model
- 16. type of tissue that contracts, or shortens, to produce movement. Includes skeletal, cardiac, and smooth.
- 19. propels the cell, only in sperm
- 20. increase surface area for absorption
- 22. dissolving medium present in larger quantity
- 24. flattened
- 27. solutions contain fewer solutes (more water) than the cells do, cells will enlarge
- 29. column-like structure
- 30. substances are transported across the membrane without any input from cell
- 31. "cell eating"
- 32. prevent cells from being pulled apart
- 33. solutions contain more solutes than cells, causes cells to shrink
Down
- 1. active transport example
- 3. the cell provides the metabolic energy (ATP) to drive the transport process
- 4. type of tissue found everywhere in the body to connect body
- 6. move materials across the cell surface. (located in respiratory system to move mucus)
- 7. waterproof
- 9. "cell drinking"
- 11. more than 1 layer
- 13. unassisted process, solutes are lipid-soluble enough to pass through membrane pores
- 15. substances are moved across membrane "in bulk" without actually crossing the plasma membrane
- 17. components in smaller quantities within a solution
- 18. contents of vesicle are emptied inside the cell
- 21. simple diffusion of water across a selectively permeable membrane
- 23. contents of vesicle are emptied outside the cell
- 25. type of tissue that covers and lines body surfaces
- 26. type of tissue that receives and conducts electrochemical impulses to and from body parts.
- 28. solutions have same solute and water concentrations as cells
