500 Facilitated Diffusion
100 True or False: The solution a cell is in effects the type of transport a cell uses?
200 A solution that has the same concentration inside as outside of the cell is called what?
300 There are numerous molecules embedded into the cell membrane, but what is it chiefly made of?
300 Phospholipid bilayer
400 If these are very large molecules, then this is what type of solute?
500 Why cant most organisms live in salt solutions more concentrated than salt water?
500 They would dehydrate
100 The passage of materials into and out of the cell is regulated by?
100 The cell membrane
200 True or False: Cell membranes are able to trap small molecules from leaving?
200 False – Small molecules can move through the membrane through osmosis
300 True or False: Ions can not pass through a cell membrane without the cell expending energy?
300 False – Facilitated Diffusion can move ions
400 A cell membrane regulates what three things?
400 Waste, Water, and Nutrients

400 The lysosome
500 What organelle is the FedEx of the cell?
500 Golgi Apparatus
Final Jeopardy Name two differences and two similarities between active and passive transport.
Similarities Both move molecules Both (can) move down the concentration gradient Differences Passive doesnt need energy while active does Active can go up or down the concentration gradient and passive can only go down
