Cell Processes 1

How are active transport and passive transport different?

• Passive transport requires energy and active transport does not. 
• Active transport includes diffusion, and passive transport does not. 
• Active transport requires energy, and passive transport does not.

Diffusion is the natural movement of molecules from...

• cold to hot environments
• areas of high concentration to areas of low concentration
• areas of low concentration to areas of high concentration

How the cell processes help to maintain the basic needs of organisms?

• It allows the cell to remove waste and take in nutrients

• Helps them move

• Helps them reproduce

Which active transport process releases substances from a cell?

• hypocytosis
• endocytosis
• exocytosis
• mesocytosis

What is osmosis? 

• the same as photosynthesis
• the division of cells
• the movement of water molecules through a selectively permeable membrane

What is diffusion?

• when molecules move 
• when molecules move from a high concentration to a low.
• no movement 
• molecules move everywhere

Passive transport

•  always occurs slowly
•  does not require energy
• requires energy
