Osmosis Information

Question 1

What is the concentration gradient?

Answer 1

Going from a high concentration to a low concentration.

Question 2

What is osmosis?

Answer 2

Osmosis is the movement of water from an area of high concentration to one of a low concentration.

Question 3

Why do we repeat tests?

Answer 3

It makes our investigation more valid, as it shows that the result is not an “one-off” or an outlier result.

Question 4

If the concentration of water is greater outside the cell than inside the cell, what will happen?

Answer 4

Water will flow into the cell via osmosis, the cell will become more turgid

Question 5

If the concentration of water is lower outside the cell than inside the cell, what will happen?

Answer 5

Water will flow out of the cell via osmosis, the cell will become more turgid

Question 6

What should I include in my evaluation?

Answer 6

• Is my conclusion justified?
• What did I do to make my investigation more valid?
• What could I have done better to make my investigation more valid?

Question 7

What should I include in my discussion?

Answer 7

Link the results you got, and your conclusion, to the theory around osmosis.
