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.

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

• active transport
• endocytosis
• passive transport
• exocytosis

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

What is the name of the process in which molecules move from an area of high concentration to an area of low concentration directly across a selectively permeable membrane?

• 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 

Two examples of passive transport are

• Earth and Sun

• Diffusion and Osmosis

• Energy and Wind

• Protein Pumps and Exocytosis

Most active transport proteins use energy from the breakdown of:

• nucleus
• cell membrane
• ATP
• mitochondria

The movement of molecules against a concentration gradient

• simple diffusion
• facilitated diffusion
• active transport
• osmosis
