Cell Transport

Front

What is Active Transport?

Back

Active Transport is the movement of molecules into or out of a cell from low concentration to high concentration, using energy.

Front

What is Endocytosis?

Back

Endocytosis is a type of cell transport where the cell engulfs material from outside, bringing it into the cell.

Front

What is Exocytosis?

Back

Exocytosis is the process where a cell expels materials to the outside environment.

Front

What is Osmosis?

Back

Osmosis is the movement of water molecules through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is Diffusion?

Back

Diffusion is the movement of molecules from an area of high concentration to an area of low concentration without using energy.

Front

What is Facilitated Diffusion?

Back

Facilitated Diffusion is the process where molecules pass through a cell membrane via a protein channel, moving from high to low concentration.

Front

What is Passive Transport?

Back

Passive Transport is the movement of substances across a cell membrane without the use of energy.

Front

What is a Hypotonic Environment?

Back

A Hypotonic Environment is when the concentration of solutes outside the cell is lower than inside, causing water to enter the cell.

Front

What is a Hypertonic Environment?

Back

A Hypertonic Environment is when the concentration of solutes outside the cell is higher than inside, causing water to leave the cell.

Front

What is a Semi-Permeable Membrane?

Back

A Semi-Permeable Membrane is a barrier that allows certain substances to pass while blocking others.
