___ is particle movement from an area of lower concentration to an area of higher concentration.

• Active transport

• Passive transport

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

Active transport requires energy because...

• The cell is moving something against a concentration gradient
• The cell is moving something with a concentration gradient

The cell membrane is responsible for allowing molecules to diffuse into or out of the cell. What type of movement is diffusion?

• Passive transport

• Active transport

Passive transport is when molecules move ________ the concentration gradient.

• against

• up

• down

This picture is a representation of what type of transport?

• Osmosis because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of high concentration to low concentration.

• Facilitated diffusion because it is diffusing through a protein from an area of low concentration to high concentration.

• Simple diffusion because it is diffusing through a protein from an area of high concentration to low concentration.
