Passive Transport

Front

What is Passive Transport?

Back

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

Front

What regulates what enters and leaves a cell?

Back

The Cell Membrane regulates what enters and leaves a cell.

Front

Does Passive Transport require energy?

Back

No, Passive Transport does not require energy.

Front

What is Equilibrium in the context of cell transport?

Back

Equilibrium is when there is an equal amount of substance on either side of the membrane.

Front

What is Osmosis?

Back

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

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 a semi-permeable membrane?

Back

A semi-permeable membrane allows certain substances to pass through while blocking others.

Front

What is diffusion?

Back

Diffusion is the movement of particles from an area of high concentration to an area of low concentration.

Front

What is the role of the Cell Membrane?

Back

The Cell Membrane protects the cell and controls the movement of substances in and out.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.
