cell transport mechanisms

Diffusion and is it passive or active

Diffusion is passive

When molecules go from a higher concentration to a lower concentration

Filtration

Filtration is passive

Materials moving out of the capillaries due to the force of blood pressure.

Passage of water containing dissolved materials through membranes as a result of mechanical pressure (pushing)

Active transport

Active transport is active

Moves molecules from an area of low concentration to high concentration

Osmosis

Osmosis is passive

The movement of water from a higher concentration concentration to a lower concentration

An example of osmosis is the water from extracellular fluid into the cells or the movement of water from cells to extracellular fluid
