Tonicity

Front

What is the process called when solute moves through the cell membrane from high to low concentration?

Back

Diffusion

Front

What type of solution causes a cell to swell due to water moving into it?

Back

Hypotonic solution

Front

In a hypotonic solution, which direction does water move in relation to the cell?

Back

Water moves into the cell.

Front

What is the term for a solution that has the same concentration of solutes as the inside of a cell?

Back

Isotonic solution

Front

What happens to a cell placed in a hypertonic solution?

Back

The cell shrinks as water moves out.

Front

Define tonicity in the context of cell biology.

Back

Tonicity refers to the ability of a surrounding solution to cause a cell to gain or lose water.

Front

What is the effect of an isotonic solution on a cell?

Back

There is no net movement of water; the cell remains the same size.

Front

What is the primary factor that determines the direction of water movement across a cell membrane?

Back

The concentration gradient of solutes.

Front

What occurs during osmosis?

Back

The movement of water across a selectively permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

How does a hypertonic solution affect the osmotic pressure of a cell?

Back

It increases osmotic pressure, causing water to leave the cell.
