Passive transport

Front

What does it mean for a cell membrane to be selectively permeable?

Back

Cell membranes regulate which substances can enter and exit the cell.

Front

What type of passive transport uses proteins to help molecules pass through the membrane?

Back

Facilitated diffusion.

Front

What is the state called when both inside and outside of a cell have the same amount of water?

Back

Dynamic Equilibrium.

Front

Does passive transport require cell energy?

Back

No, passive transport does NOT require cell energy.

Front

Which part of the cell controls the movement of substances?

Back

Cell membrane.

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?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is facilitated diffusion?

Back

A type of passive transport that uses proteins to help move molecules across the cell membrane.

Front

What is the role of the cell membrane?

Back

To control the movement of substances in and out of the cell.

Front

What happens to a cell in a hypertonic solution?

Back

The cell loses water and may shrink.
