The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell
• Certain things can enter while others cannot
• The cell manually sorts through all materials
• Only certain cells can interact with the cell.

A can of air freshener is sprayed in the opposite side of the room.  Ten minutes later you start to smell the scent.  This is an example of 

• diffusion
• active transport
• endocytosis
• osmosis

Controlling what goes into or out of the cell without energy is called

What is it called when molecules move across the cell membrane from an area of high concentration to an area of low concentration through a carrier protein?

• Diffusion
• Osmosis
• Active Transport
• Facilitated Diffusion

When molecules are spread evenly across the cell membrane, ______________________ is reached.

• difference
• transportation
• equilibrium
• solution

What is the difference between active and passive transport?

• Active does not need energy and passive uses ATP (energy)
• Active uses ATP (energy) and passive does not need energy
• Active stores transport proteins and passive releases 
• Active uses hormones and passive does not 

Permeable means

• things can pass through
• the concentration levels are different
• it is permanent
• things are stuck
