Cellular Transport Flashcard

Front

What happens to a cell placed in extremely salty water?

Back

Water would leave the cell.

Front

What is it called when the number of molecules of a substance are equal on either side of a cell membrane?

Back

Equilibrium.

Front

What process caused the changes in the egg from our experiment?

Back

Osmosis.

Front

What does semipermeable mean?

Back

Some substances can cross the membrane while others cannot.

Front

Which type of cellular transport does not require energy from the cell?

Back

Passive transport.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is osmosis?

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

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 the role of the cell membrane?

Back

To protect the cell and control what enters and leaves the cell.
