Lab Osmosis and Diffusion

Question 1

How do water molecules diffuse

Answer 1

From area of high concentration to low concentration

Question 2

The concentration of water vs solute in aqueous solution

Answer 2

Water decreases when solute increases, vise versa ( since the solute takes up space that would otherwise be full of water.

Question 3

Osmosis

Answer 3

The diffusion of water across a cell membrane

Question 4

The direction water moves depends on

Answer 4

The concentration gradient across the membrane

Question 5

In an aqueous solution water tends to diffuse either into or out of cells. Why

Answer 5

Because the cytoplasmic membrane is permeable to water but impermeable to polar solutes dissolved in the water.

Question 6

Tonicity

Answer 6

Refers to the concentration of solute compared to inside of the cell

Question 7

a solution hypertonic to the cell

Answer 7

High solute/ low water

Question 8

The effect of hypertonic solution on a cell

Answer 8

cell: low solute /high water

The water would diffuse out the cell would shrink

Question 9

Hypotonic

Answer 9

Low solute/High water

Question 10

The effect of hypotonic solution on a cell

Answer 10

high solute/ low water

Water will diffuse in and possibly burst
