Passive Transport

Front

What is Passive Transport?

Back

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

Front

What is the main goal of Passive Transport?

Back

To have molecules reach equilibrium.

Front

Define Selective Permeability.

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

What happens to a cell in a hypertonic solution?

Back

The cell undergoes plasmolysis, causing it to shrink.

Front

What is Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration.

Front

What is Facilitated Diffusion?

Back

A type of passive transport that uses protein channels to help move molecules across the cell membrane.

Front

What is Osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

How do water molecules move during osmosis in a hypertonic solution?

Back

Out of the cell, causing the cell 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.

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.
