Osmosis is specifically.....

diffusion of water molecules through a semi-permeable mebrane from an area of low concentration to an area of high concentration

the diffusion of particles from an area of high concentration to an area of low concentration

diffusion of water molecules through a semi-permeable membrane from an area of high concentration to an area of low concentration

the diffusion of particles from an area of low concentration to an area of high concentration

In which case would a cell most likely shrink?

when placed in a solution containing a high salt concentration

when placed in a isotonic solution

when placed in a solution containing a low pH

when placed in a solution containing distilled water

Active transport requires energy because...

The cell is moving something against a concentration gradient

The cell is moving something with a concentration gradient

A student noticed that placing wilted lettuce in a bowl of cool water caused the lettuce to become more crisp and firm. What is the best explanation for his observation?

Water moved into the lettuce cells by active transport.

Water moved into the lettuce cells by osmosis.

Salt moved into the lettuce cells by diffusion.

Water moved out of the lettuce cells by osmosis.

_______ regulates what enters and leaves a cell.

Cell Membrane

Nucleus

Mitochondria

Cytoplasm

Where is there a low concentration of dye?

at the bottom of cup

in the color

at the top of cup

no concenteraion gradient

The picture below is an example of _________________.

osmosis

isotonic

diffusion

active transport

Where will the water go?

Into the cell

Out of the cell

Equally in & out - it's isotonic

There is no water

Nemo and other ocean dwelling fish cannot survive in freshwater because......

freshwater is hypertonic to Nemo's cells and will result in water leaving them causing the cells to shrink

freshwater is hypotonic to Nemo's cells and will result in water leaving them causing the cells to shrink

freshwater is hypertonic to Nemo's cells and will result in water entering them causing the cells to swell and burst

freshwater is hypotonic to Nemo's cells and will result in water enter them causing the cells to swell and burst

10.

In the cell pictured, which way would water move?

Into the cell, causing the cell to swell

Out of the cell, causing the cell to shrink

In and out of the cell equally, keeping the shape the same

11.

In the cell pictured, where would water move?

Into the cell, causing it to swell

Out of the cell, causing it to shrink

In and out of the cell equally, causing the shape to stay the same

12.

In the cell pictured, which way would water move?

Into the cell, causing the cell to swell

Out of the cell, causing the cell to shrink

In and out of the cell equally, keeping the shape the same

13.

In the given scenario what will happen? An egg is placed in pure water for 48 hours.

The egg will gain water and swell.

Water will move in and out of the cell equally, and the cell with neither shrink nor swell.

The egg will lose water and shrink.

14.

Ideally, your cells should be in a(n) _______ solution

Hypertonic

Hypotonic

Isotonic

Cola

15.

The cell below is in a _________ solution.
