Cell Transport

Front

What regulates what molecules enter and leave the cell?

Back

Cell Membrane

Front

What do diffusion, osmosis, and facilitated diffusion have in common?

Back

They move molecules DOWN the concentration gradient.

Front

What is the term for the movement of water across a selectively permeable membrane?

Back

Osmosis

Front

What is the process called when molecules move from an area of high concentration to an area of low concentration?

Back

Diffusion

Front

What is the term for the state when the concentration of a certain molecule is the same on both sides of a cell membrane?

Back

Equilibrium

Front

What type of transport requires energy to move molecules against the concentration gradient?

Back

Active Transport

Front

What happens to a cell when water moves out of it?

Back

The cell will shrink.

Front

What is facilitated diffusion?

Back

A process that allows molecules to cross the membrane with the help of transport proteins, moving down the concentration gradient.

Front

What is hypertonicity?

Back

A condition where the concentration of solutes outside the cell is greater than inside, causing water to move out of the cell.

Front

What is isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.
