osmosis

Front

What is osmosis?

Back

The diffusion of water across a semi-permeable membrane.

Front

What happens to a cell in a hypotonic solution?

Back

Water moves into the cell, causing it to swell.

Front

What is a semi-permeable membrane?

Back

A membrane that allows certain molecules to pass through while blocking others.

Front

What is the difference between osmosis and diffusion?

Back

Osmosis specifically refers to the movement of water, while diffusion refers to the movement of any substance from high to low concentration.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What occurs to a cell in a hypertonic solution?

Back

Water moves out of the cell, causing it to shrink.

Front

Define isotonic solution.

Back

A solution with the same concentration of solutes as another solution, resulting in no net movement of water.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is passive transport?

Back

The movement of molecules across a membrane without the use of energy, following the concentration gradient.

Front

What role do aquaporins play in osmosis?

Back

Aquaporins are proteins that facilitate the rapid transport of water across cell membranes.
