lower, higher

Front

What are the 2 kinds of passive transport?

Back

Diffusion and osmosis

Front

What is osmosis?

Back

The movement of water molecules through a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is active transport?

Back

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

Front

What is a selectively permeable membrane?

Back

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

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.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to the inside of the cell, causing water to move out of the cell.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to the inside of the cell, causing water to move into the cell.
