Cell tonicity

Which of the following terms describes a solution that contains the same solute concentration as the cell?

• Hypotonic

• plasmotonic

• Hypertonic

• Isotonic

In a solution of 10% sugar and 90% water, I have placed a simulated cell that contains 30% sugar and 70% water. Which of the following describes OSMOSIS in this situation?

• Water moves into the cell

• Water moves in and out equally

• Water does not move in the above situation

• Water moves out of the cell

In a solution of 20% sugar and 80% water, I have placed a simulated cell that contains 13% sugar and 87% water. Which of the following describes OSMOSIS in the situation?

• Water moves into the cell

• Water does not move in the above situation

• Water moves out of the cell

• Water move in and out equally

In a solution of 20% salt and 80% water, I have placed a simulated cell that contains 20% salt and 80% water. Which of the following describes OSMOSIS in the situation?

• Water moves into the cell

• Water moves in and out equally

• Water does not move in the above situation

• Water moves out of the cell

A cell loses water to the outside solution when the solution is:

• Intravenous

• Hypotonic

• Hypertonic

• Isotonic

A person is lost at sea for 10 days. The person is out of drinkable water, decides as a last resort to consume ocean water. What will happen to the body cells?

• The cells will take in so much water they explode

• The cells will regain water and return to the normal state

• The cells lose water and crenate

• None of the above

A solution in which the cell contains more solute than the solution is:

• Hypotonic

• Isotonic

• Intravenous

• Hypertonic

Celery stocks that are immersed in freshwater for several hours become stiff and hard. Similar stocks left in a salt solution become limp and soft. From this we can deduce that the cells of the celery stocks are

• Hypertonic to both fresh water and the salt solution

• Hypertonic to freshwater but hypotonic to the salt solution

• Hypotonic to freshwater but hypertonic to the salt solution

• Hypotonic to both freshwater and the salt solution

A cell would lose water and shrink in which of the following solutions:

• Hypertonic

• Isotonic

• Ringers

• hypotonic
