What property of the cell membrane makes it selectively permeable?

The fact that the majority is hydrophobic

The fact that the majority is hydrophilic

What is one major difference between passive and active transport?

Active transport uses energy; passive transport does not.

Passive transport uses energy; active transport does not.

Both types of transport use energy.

No difference. They are both the same.

When looking at the cell membrane, where are the phosphate heads located?

Floating between bilayer levels

Located at different parts throughout the bilayer

When looking at the cell membrane, where are the lipid tails located?

Goes through each end of the bilayer

How is diffusion (left) different from the process on the right?

Diffusion transfers particles from an area of high to low concentration.

Diffusion takes place due to osmotic pressure.

Diffusion requires cellular energy for the transfer of molecules.

Diffusion requires protein channels as a passage-way for particles

Describe the movement of molecules going through the proteins in the illustration.

Molecules are moving from a lower concentration to a higher concentration.

Molecules are moving from a higher concentration to a lower concentration.

Molecules are moving from a higher concentration to a lower concentration and then from a lower to higher concentration.

Molecules are moving from a lower concentration to a higher concentration and then from a higher concentration to a lower concentration.

An animal cell that is surrounded by fresh water will burst because the osmotic pressure causes

solutes to move out of the cell.

Osmosis occurs when there is a different concentration of solute molecules on each side of the membrane. The drawing below shows a beaker containing a 30% salt solution and a suspended cell containing a 10% salt solution. What statement best describes the cell after 20 minutes?

Water will move from the cell into the beaker, resulting in a smaller cell.

Water will move from the beaker into the cell, resulting in a larger cell.

Salt will move from the cell into the beaker, resulting in a smaller cell.

Salt will move from the beaker into the cell, resulting in a larger cell.

If you put a plant in salt water it will ...

shrivel because water diffuses out of the cell

swell because water diffuses into the cells

swell because water diffuses out of the cell

When a cell is placed in a hypertonic solution water

moves from the inside of the cell to the solution

moves from the solution to the inside of the cell

moves equally in and out of the cell

A cell will __________________ in a hypotonic solution.

the size of the cell will not change

the size of the cell will change from large to small and from small to large

An organism that lives in a hypertonic environment may develop an adaptation to slow down water loss to the environment. If an organism were to develop in a hypotonic environment, what sort of adaptation might it develop?

One that would allow it to slow water gain from its environment

One that would allow it to have better camouflage

One that would pump water into the cell

It wouldn’t need an adaptation because there would be no net water movement

If there is 5 percent water inside a cell and 5 percent water outside a cell

There will be no movement of water cells

more water will move inside the cell

more water will move outside the cell

A plant cell is placed in a solution whose solute concentration is twice as great as the concentration of the cell cytoplasm. The cell membrane is selectively permeable, allowing water but not the solutes to pass through. What will happen to the cell?

The cell will shrivel because of osmosis.

The cell will swell because of osmosis.

The cell will shrivel because of active transport of water.

The cell will swell because of active transport of water.
