Passive Transport

Front

What is Passive Transport?

Back

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

Front

What is Diffusion?

Back

The process where molecules move from a high concentration to a low concentration.

Front

What is the role of the Cell Membrane?

Back

Regulates what enters and leaves a cell.

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing others.

Front

What happens when there is equal concentration of water inside and outside a cell?

Back

There will be no movement of water cells.

Front

What is Osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between Active and Passive Transport?

Back

Active transport requires energy, while passive transport does not.

Front

What is facilitated diffusion?

Back

A process where molecules pass through the cell membrane with the help of transport proteins.

Front

What is a concentration gradient?

Back

A difference in the concentration of a substance across a space.

Front

What is equilibrium in terms of diffusion?

Back

A state where the concentration of a substance is equal throughout a space.
