Cell transport

Front

What is passive transport?

Back

Passive transport is the movement of molecules across a cell membrane without the use of energy, moving with the concentration gradient.

What is diffusion?

Back

Diffusion is the process by which molecules spread from areas of high concentration to areas of low concentration.

Front

What type of movement is described when dye molecules move from high to low concentration?

Back

Diffusion; the dye molecules are moving from high to low concentration.

Front

What regulates what can enter and leave the cell?

Back

The cell membrane regulates what can enter and leave the cell.

Front

What is the function of the plasma membrane?

Back

The plasma membrane protects the cell and controls the movement of substances in and out.

Front

What type of solution causes a cell to swell?

Back

Hypotonic solution causes a cell to swell as water enters the cell.

Front

What type of solution causes a cell to shrink?

Back

Hypertonic solution causes a cell to shrink as water leaves the cell.

Front

What is osmosis?

Back

Osmosis is the diffusion of water molecules across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via a protein channel.
