100

The solute concentration of this solution is lower than the solute concentration inside the cell.

Hypotonic

100

When calculating solute potential, what is i (ionization constant) for sucrose?

i=1

100

Red blood cells containing 10% NaCl are surrounded by a 10% NaCl solution.

No net movement

100
This is what it's called when plant cells lose water from their vacuoles and their cell membranes pull away from the cell membrane.

Plasmolysis

200

The solute concentration in this type of solution is equal to the solute concentration inside the cell.

Isotonic

200

When calculating solute potential, what is i (ionization constant) for NaCl?

i=2

200

A cell that has a 2.0 M sucrose concentration is placed in a 1.0 M sucrose solution.

Into the cell

200
This is what it's called when animal cells swell and burst with water.

Cytolysis

300

The solute concentration of this solution is higher than the solute concentration inside the cell.

Hypertonic

300

What is the water potential of solution in an open air beaker with solute potential of -5.4 bars?

-5.4 bars

300

A cell that is 0.2% NaCl is placed in a beaker containing a 1.0% NaCl solution.

Out of the cell

300

When a plant cell is immersed in a hypotonic solution, what happens to turgor pressure?

It increases

400

Putting a plant in this solution will result in plasmolysis and cause the plant to wilt.

Hypertonic

400

Calculate solute potential for a 0.5 M sucrose solution at 30°C. Round to tenths.

-12.6 bars

400

Plant cells containing 0.6 M sucrose are placed in pure water.

Into the cell

400

What would happen to plant cells exposed to very salty soil?

They would undergo plasmolysis (lose water)

500

When an animal cell is placed in this solution, water enters the cell and causes cytolysis.

Hypotonic

500

Calculate water potential for a 0.8 M NaCl solution in an open air beaker at 0°C.

-36.3 bars

500

Plant cells containing 0.4 M NaCl are immersed in 3.0 M NaCl.

Out of the cell

500
Red blood cells are 0.9% NaCl. What happens to the red blood cells when a patient is given an IV with pure water?

They burst (cytolysis)
