Front

In a solution of salt water, salt is considered the _____.

Back

Solute

Front

In the cell pictured, where would water move?

Back

Out of the cell, causing it to shrink

The picture below is an example of _________________

Diffusion

Front

Osmosis is the diffusion of ____ across a selectively permeable membrane.

Back

Water

Front

Osmosis is specifically.....

Back

Diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

Define diffusion.

Back

The process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What is a selectively permeable membrane?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

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

Front

What is an isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
