6. The Membrane

The movement of molecules across the capillary wall due to differences in hydrostatic pressure is called:

Which of the following structures acts as a barrier that restricts the flow of water during osmosis in animal cells?

Which of the following best describes what happens to a red blood cell when placed in a hypertonic solution?

Which of the following best describes osmosis?

Decreased volume and increased concentration of the extracellular fluid (ECF) is defined as:

When will water stop moving across a semipermeable membrane during osmosis?

A human cell placed into a hypertonic solution is likely to:

Diffusion and osmosis are examples of which type of cellular transport?

The concentration of solutes in a red blood cell is about 2%, but red blood cells contain almost no sucrose or urea. Sucrose cannot pass through the membrane, but water and urea can. Osmosis would cause red blood cells to shrink the most when immersed in which of the following solutions?

What happens to a plant cell when it is placed in a salt water (hypertonic) solution?

Which of the following would result in no change in osmotic pressure across a semipermeable membrane?

The internal solute concentration of a plant cell is about 0.8 M. To demonstrate plasmolysis, it would be necessary to suspend the cell in what solution?

A single plant cell is placed in an isotonic solution. Salt is then added to the solution. Which of the following would occur as a result of the salt addition?

If a plant cell loses water at the same rate that it takes in water, what type of solution is it in?

Which of the following best describes osmosis as a special kind of diffusion?
