Passive Transport

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

Front

Does Passive Transport require cell energy?

Back

No, Passive Transport does NOT require cell energy.

Front

What is diffusion?

Back

Diffusion is when molecules move from a high concentration to a low concentration.

Front

Which process moves with the concentration gradient?

Back

Diffusion moves with the concentration gradient.

Front

What is the main characteristic of Passive Transport?

Back

Passive Transport involves the movement of materials across the cell membrane without the use of energy.

Front

What is osmosis?

Back

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

Front

What happens to a cell in a hypertonic solution?

Back

In a hypertonic solution, water moves out of the cell, causing it to shrink.

Front

What happens to a cell in a hypotonic solution?

Back

In a hypotonic solution, water moves into the cell, causing it to swell.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is the process of passive transport of molecules across a cell membrane via specific transmembrane integral proteins.

Front

What is the concentration gradient?

Back

The concentration gradient is the difference in the concentration of a substance between two areas.
