Controlling what goes into or out of the cell with the help of energy is called

• active transport
• endocytosis
• passive transport
• exocytosis

Which form of active transport is being shown? (Inside of  the cell is tan colored) 

• Facilitated Diffusion
• Exocytosis
• Endocytosis
• Receptor-mediated endocytosis

The sodium-potassium pumps requires energy to move ions across the cell membrane against their concentration gradient so it is a type of

• active transport
• osmosis
• diffusion
• facilitated diffusion

A saltwater snail is placed in freshwater. What happens to its cells?

• They shrink
• They swell
• Nothing happens

 Engulfing of bacteria by white blood cells is called as

• Phagocytosis
• Pinocytosis
• Exocytosis
• Endocytosis

If you looked at red blood cells under a microscope and saw the blood cells exploded, what would you say happened?

• The cells were placed in a hypotonic solution.
• the solution was isotonic.
• The solution was hypertonic.

A lab tech performed a routine RBC count.  The cells appeared shriveled and were difficult to count.  What was wrong with the cell storage solution.

• It was hypertonic
• It was hypotonic
• It was isotonic

A shrinking of the cytoplasm away from the wall due to outward osmotic flow of water

• turgor pressure
• hemolysis
• Osmotic pressure
• plasmolysis

A cell in an isotonic solution will

• swell
• shrink
• stay the same size
• impossible to tell
