• concentration gradient

• concentration

• [high] --> [low]

Way to display that molecules are moving from an area of high concentration to an area of low concentration.

• concentration gradient

• concentration

• high --> low

Facilitated diffusion is the movement of materials into and out of the cell

• with the use of energy

• with the use of proteins but no energy

• by moving water

• by using ATP

The  movement of water from a high concentration to a low concentration is called

• diffusion

• osmosis

• facilitated diffusion

• active transport

Semi-permeable mean to allow

• all materials across the membrane

• only some materials across the membrane

• no material to cross the membrane

• to allow only water across the membrane

What process occurs when WATER diffuses across a membrane?

• endocytosis

• mitosis

• osmosis

• nuclear fission 

Osmosis is the movement of _____ across a membrane.

• food

• energy

• oxygen

• water

In passive transport, .............

• energy is required

• energy is not required

The picture below is an example of _________________ .

• osmosis

• isotonic

• diffusion

• active transport

In PASSIVE TRANSPORT, substances move from:

• High concentration to low concentration

• Low concentration to high concentration
