Cell Transport

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

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 diffusion of water molecules only through a membrane 

• diffusion 
• osmosis
• facilitated diffusion 

Why are there more dye particles in the right side of the membrane after 30 minutes?

• The membrane allowed active transport to take place.

• The membrane is not like the cell membrane, so the dye can get through.

• Only dye particles could move through the membrane.

• Some of the dye molecules diffused through the membrane.

What process is shown in the image?

• endocytosis

• active transport

• facilitated diffusion

• osmosis

​ ​ (a)   does NOT require energy.

• passive transport
• active transport
• endocystosis
• exocytocisi

What does “high concentration area” mean?

• Spread out
• Tightly packed together
• Uncrowded
• Spacious

When particles move from areas of high concentration to areas less concentrated, this has taken place.

• diffusion
• mitosis
• endocytosis
• photosynthesis
