Flashcard Set Questions
1. In reporting lab results, what should be ...
Independent variable is always on the X axisDependent variable is always on the Y axissee mnemonics
2. During osmosis, what structures allo...
aquaporins (special protein channels)
3. Water always travels from a region of ___...
Water always travels from a region of _higher__ water potential to a region of _lower____ water potential.
4. What are the components of water potentia...
Water potential = solute potential + pressure potentialsee explanation
5. Imagine a dialysis tubing bag used to mod...
The bag will LOSE water/mass because a 5% sucrose solution is 95% water and the 10% sucrose in the beaker is only 90% water. The water will follow the gradient from high to low concentration of water. Therefore the water will go from 95 % to 90 % (i.e. OUT of the bag)
6. Imagine a dialysis tubing bag used to mod...
The bag is hypotonic and the beaker is hypertonic.
7. Does water have a net movement from hyper...
Water moves toward the hypertonic solution, meaning it moves from hypo to hyper.see mnemonic
8. An animal cell is placed in distilled wat...
The animal cell is hypertonic because it must have more solutes than distilled water (and therefore it has a lower water concentration).The cell will gain water and burst/lyse.
9. What will happen to a plant cell in salt ...
cell will lose water because the salt water is hypertonic to the cell.the cell becomes flaccid.
10. Compare the results of placing animal and...
animal cells burst, but plant cells become turgid since they have cell walls which prevent bursting.

In reporting lab results, what should be recorded on the X axis of your graphs? What about the Y axis? Independent variable is always on the X axisDependent variable is always on the Y axissee mnemonics Dry Mix (Dependent or Responding variable goes on the Y Manipulated or Independent variable goes on the X)Or just remember that the Dependent goes on the Y and Independent goes on the X
