Water Lab Terminology

7. A cell releasing substances by merging a vesicle with the membrane—like releasing a bubble.
9. The flexible nature of the cell membrane that lets parts move freely—like oil on water.
17. The concentration of dissolved substances in solutions separated by a membrane—affecting water movement.
19. Movement of molecules from high to low concentration without using energy—like a scent spreading in a room.
20. Movement of water through a membrane from low to high solute concentration—like water moving to a saltier area.
21. A cell taking in substances by engulfing them—like absorbing a bubble.
22. The thin outer layer of a cell that controls what goes in and out—like a security gate.
23. A protein that helps substances move in and out of the cell—like a doorway.
24. The main energy molecule cells use—like a battery for the cell.

1. When something gets smaller or shrinks.
2. Attracted to water—water-loving.
3. A protein that helps substances cross the cell membrane—like a ferry.
4. A solution with more dissolved substances than another—like salty water.
5. When molecules keep moving but are evenly spread out—like people evenly spaced but still moving around.
6. How much substance is dissolved in a liquid—how much stuff is in the water.
8. Movement of substances across a membrane with help from proteins, without energy—like sliding down with assistance.
10. When something gets bigger or swells up.
11. Movement of substances from low to high concentration across a cell membrane using energy—like pushing something uphill.
12. Two solutions with the same amount of dissolved substances—balanced.
13. A solution with fewer dissolved substances than another—like pure water.
14. When something doesn't change in size.
15. A membrane that lets some substances pass but blocks others—like a filter.
16. Transport Movement of substances from high to low concentration without energy—like rolling downhill.
18. Repelled by water—water-fearing.
