Cell processes Review (active and passive)

Front

What is Endocytosis?

Back

An active transport process where a cell membrane surrounds a particle and encloses it in a vesicle to bring the particle into the cell.

Front

What is diffusion?

Back

The process where molecules move from a high concentration to a low concentration.

Front

What does permeable mean?

Back

It means that things can pass through.

Front

What is Selective Permeability?

Back

The ability of the cell membrane to allow some things to pass through while preventing others.

Front

How do substances diffuse by osmosis in and out of a cell?

Back

Substances move from greater to lesser concentration.

Front

What is active transport?

Back

The movement of substances across a cell membrane that requires energy.

Front

What is passive transport?

Back

The movement of substances across a cell membrane without the use of energy.

Front

What is osmosis?

Back

The diffusion of water molecules across a selectively permeable membrane.

Front

What is a hypertonic solution?

Back

A solution with a higher concentration of solutes compared to another solution.

Front

What is a hypotonic solution?

Back

A solution with a lower concentration of solutes compared to another solution.
