Which structures are found in plant cells, but not in animal cells?

• Cell membranes and mitochondria
• Vacuoles and cholorplasts
• Cell walls and cytoplasm
• Chloroplasts and cell walls

What is the function of the cell membrane, in ALL living organisms?

• Provides support and structure in the cell.
• Synthesizes protein for ATP for the cell.
• Storage of raw materials (food) and ATP for the cell. 
• Regulates the transport of materials into and out of the cell.

The cell membrane contains channels and pumps that help move materials from one side to the other. What are these channels and pumps made of?

• carbohydrates
• lipids
• bilipids
• proteins

During diffusion, when the concentration of molecules on both sides of a membrane is the same, the molecules will

• move across the membrane to the outside of the cell.
• stop moving across the membrane.
• continue to move across the membrane in both directions.
• move across the membrane to the inside of the cell.

The diffusion of water across a selectively permeable membrane is called

• osmotic pressure.
• osmosis.
• pinocytosis.
• active transport.

Which means of particle transport requires input of energy from the cell?

• diffusion
• osmosis
• facilitated diffusion
• active transport

Which means of particle transport is shown in this diagram?

• endocytosis
• exocytosis
• facilitated diffusion
• protein pump
