Osmosis Review

Front

What is an isotonic solution?

Back

An isotonic solution is one that has the same concentration of solutes as the cell placed in it, resulting in no net movement of water.

Front

What does hypertonic mean in terms of osmotic conditions?

Back

Hypertonic refers to a solution that has a higher concentration of solute outside the cell than inside, causing water to move out of the cell.

Front

What happens to cells in a hypotonic solution?

Back

Cells in a hypotonic solution will swell and may burst because water rushes into the cell.

Front

What is the effect of drinking seawater on human cells?

Back

Drinking seawater, which is hypertonic, causes dehydration as water moves out of the cells to balance the salt concentration.

Front

What is a hypertonic solution's effect on cells?

Back

A hypertonic solution causes cells to lose water and shrink due to the higher solute concentration outside the cell.

Front

Define osmosis.

Back

Osmosis is the movement of water across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is a hypotonic solution?

Back

A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water entering the cell.

Front

Explain the term 'solute'.

Back

A solute is a substance that is dissolved in a solvent, forming a solution.

Front

What is the role of a selectively permeable membrane in osmosis?

Back

A selectively permeable membrane allows certain molecules, like water, to pass through while restricting others, facilitating osmosis.

Front

What occurs during osmosis when a cell is placed in a hypertonic solution?

Back

Water moves out of the cell, leading to cell shrinkage and potential dehydration.
