What is the function of the mitochondria?

Structures that converts nutrients to energy

Structure that manufactures ribosomes

Stack of membranes that packages chemicals

Structure that contains DNA and directs the cell

What is the function of the vacuole?

Sac that stores water, nutrients, and waste products

Sac filled with digestive chemicals

Jelly-like substance within the plasma membrane

stack of membranes that packages chemicals

What is the difference between rough and smooth ER ?

Rough has ribosomes, smooth does not.

Plants have rough ER, animals have smooth ER.

What type of injuries the Doctors treat.

The following data was collected by observing subcellular structures of three different types of cells. How can you determine these are eukaryotic cells?

They have membrane bound organelles

Cells in the pancreas will incorporate radioactively labeled amino acids into proteins. This "tagging" of newly synthesized proteins enables a researcher to track their location. Predict the most likely pathway of an enzyme secreted by pancreatic cells.

ER -> Golgi apparatus -> vesicles that fuse with the plasma membrane

ER -> lysosomes -> vesicles that fuse with the plasma membrane

Golgi apparatus -> ER -> lysosome

Nucleus -> ER -> Golgi apparatus

Which of the following uses passive transport without the help of proteins to move materials across the plasma membrane?

the movement of carbon dioxide across the plasma membrane

the depolarization of a muscle cell by transporting ions across the plasma membrane

the uptake of glucose by the microvilli of cells lining the stomach

the movement of large proteins across the plasma membrane

Which of the following is true of small, nonpolar molecules?

They easily pass through a membrane's lipid bilayer

They very slowly pass through a membrane's lipid bilayer

They require transport proteins to pass through a membrane's lipid bilayer

They are actively transported across the cell membrane

The endosymbiont theory is supported by which pieces of evidence? (Select all that apply)

mitochondria have circular DNA like prokaryotes

chloroplasts contain ribosomes like prokaryotes

mitochondria use ATP like prokaryotes

chloroplasts have a contractile vacuole like prokaryotes

Which of the following is most likely to impose a limit on cell size?

ratio of surface area to volume

total volume of endoplasmic reticulum

rate of ATP production by the mitochondria

Match the following cells in solutions to their outcomes:

Animal cell placed in hypertonic solution

Animal cell placed in hypotonic solution

Plant cell placed in hypertonic solution

Plant cell placed in hypotonic solution

Plant cell placed in isotonic solution

A cell with a water potential of -1.5 bars is placed in a beaker of sugar water with $$\Psi s$$ = -4.0 bars. In which direction will the net flow of water be?

Neither into nor out of the cell

The value for $$\Psi$$ in root tissue was found to be -3.3 bars. If you take the root tissue and place it in a 0.1 M solution of sucrose at 20 $$\degree$$ C in an open beaker, what is the $$\Psi$$ of the solution, and in which direction would the net flow of water be?

$$\Psi s$$ = -2.43, net flow into the root

$$\Psi s$$ = -3.3, net flow into the root

$$\Psi s$$ = 3.3, net flow out of the root (into the solution)

$$\Psi s$$ = 2.43, net flow out of the root (into the solution)

NaCl dissociates into 2 particles in water: Na+ and Cl-. If a solution in an open beaker contained 0.1M NaCl at 20undefinedC , what is the $$\Psi$$ of the solution, and in which direction would the net flow of water be?

-4.87 bars, net flow out of the root (into the solution)

-3.3 bars, net flow out of the root (into the solution)

3.3 bars, net flow into the root

4.87 bars, net flow into the root
