Question 1

What do we call the phenomenon of all atoms and molecules constant motion?

Answer 1

Heat

Question 2

Diffusion

Answer 2

Occurs in all stages - the random motions of molecules from an area of high concentration to an area of low concentration

Question 3

Osmosis

Answer 3

Diffusion of water across a selectively permeable membrane

Question 4

Osmotic pressure

Answer 4

Pressure that can be produced by the osmosis of water

Question 5

Hyperosmotic

Answer 5

If one solution has a greater solute concentration that that of the second solution, the first solution is hyperosmotic to the second.

Question 6

Hypoosmotic

Answer 6

If one solution has a greater solute concentration that that of the second solution, the second solution is hypoosmotic to the first.

Question 7

Isosmotic

Answer 7

Two equally concentrated solutions are isomostic.

Question 8

Plasmolysis

Answer 8

The shrinking of a living cell due to osmotic water loss.

Question 9

Turgid

Answer 9

The swelling of a plant cell - doesn’t burst do to rigid cell wall

Question 10

Turgur Pressure

Answer 10

Pressure caused by osmosis - supports non-woody plants

Question 11

Independent Variable

Answer 11

The factor that you manipulate

Question 12

Dependent Variable

Answer 12

The factor you measure that varies in response to the manipulated variable.
