Moving Cellular Material

What a cell membrane is because it allows only certain substances to enter and leave a cell

• permanent
• plasma
• semipermeable
• flex wall

The movement of substances through a cell membrane without using the cell's energy

• osmosis
• passive transport
• active transport
• diffusion

A flexible covering that protects the inside of a cell from the environment outside the cell 

• Cell Membrane
• Exocytosis 
• Aerobic Respiration 

The process during which a cell's vesicles release their contents outside the cell 

• Exocytosis
• Endocytosis 
• Osmosis 

The process during which a cell takes in a substance by surrounding it with the cell membrane 

• Endocytosis 
• Exocytosis 
• Anaerobic Respiration 

Which of the following describes a state of equilibrium?

• When water molecules have stopped moving or vibrating 
• When the concentration of water outside a cell is the same as the concentration of water inside a cell 
• When a cell with a lot of water in it continues to absorb water 

The cell membrane is semi-permeable. What does "permeable" mean?

• Extremely thick
• Extremely thin
• Able to be penetrated 

What is the difference between active and passive transport?

• Active transport requires energy; passive transport does not
• Active transport moves molecules across cell membranes; passive transport does not 
• Active transport involves oxygen and water molecules; passive transport does not 

The movement of substances from an area of higher concentration to an area of lower concentration

• diffusion
• osmosis
• cellular respiration

The movement of substances through a cell membrane only by using the cell's energy 

• active transport
• passive transport
• endocytosis
