100 What is the difference between a prokaryotic and eukaryotic cell?

100 Prokaryotic - No nucleus Eukaryotic - Has nucleus

200 The demonstration I did with the aerosol spray is what kind of passive transport?

200 Diffusion

300 What type of cell is able to makes it own food?

300 Plant cell

400 Fat cells contain lots of these organelles?

400 Vacuoles - Responsible for storage

500 Name three of the people who helped to develop the cell theory.

500 Schleiden, Schwann, Virchow, Hooke, and Leeuwenhoek

100 What effects the rate of diffusion?

100 Size of the molecules diffusing and temperature

200 Bulky molecules enter a cell membrane by what process?

200 Endocytosis

300 Explain Exocytosis. What does it need? What does it do?

300 Requires energy, moves bulky molecules out of a cell

400 Explain Endocytosis. What does it need? What does it do?

400 Requires energy, moves bulky molecules into a cell

500 How do small ions pass through a cells membrane?

500 Facilitated Diffusion

100 True or False: The solution a cell is in effects the type of transport a cell uses?

100 True

200 A solution that has the same concentration inside as outside of the cell is called what?

200 Isotonic

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?

400 HypOtonic

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

500 What would happen to a cells membrane if it was placed in hypotonic starch solution?

500 It would swell

100 What organelle is responsible for the production of energy?

100 The mitochondria

200 What is the difference between vacuoles in plant and animal cells?

200 Animal - Numerous Small Vacuoles Plant - One Large Vacuole

300 What organelle is responsible for making energy from sunlight?

300 Chloroplasts

400 What organelle is responsible for the breakdown of nutrients and old organelles?

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
