Unit 2 Aca - Cell Transport Review

Front

What is an Isotonic Solution?

Back

A solution that has the same concentration of solutes and water as the cell, resulting in no net movement of water across the cell membrane.

Front

What is Active Transport?

Back

The movement of particles across a membrane from an area of lower concentration to an area of higher concentration, requiring energy.

Front

What does Semi-Permeable mean?

Back

A property of the cell membrane that allows certain substances to pass through while blocking others.

Front

What is Diffusion?

Back

The movement of molecules from an area of high concentration to an area of low concentration until equilibrium is reached.

Front

What is Homeostasis?

Back

The process by which a cell or organism maintains a stable internal environment despite changes in external conditions.

Front

What is a Hypertonic Solution?

Back

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

Front

What is Osmosis?

Back

The diffusion of water molecules across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is Facilitated Diffusion?

Back

The process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is Equilibrium in the context of cell transport?

Back

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