Water Balance

Question 0

Osmosis (passive)

Answer 0

Diffusion of water

Question 1

Simple diffusion (passive)

Answer 1

Movement from an area of high conc to an area of low conc

Question 2

Osmotic pressure

Answer 2

The force (thrust) of water movement into the higher concentration solution

Question 3

Osmolarity

Answer 3

Number of osmoles/L solution

Question 4

Tonicity

Answer 4

Ability of a solution to affect the cell

Question 5

Hypotonic solution has

Answer 5

A low concentration of solutes that do not cross the membrane. High water content (dilute) cells in this solution would absorb water and swell too dilute cell may burst (lysis)

Question 6

Hypertonic solution

Answer 6

Low water conc and high conc of solutes that do not cross membrane. Water moves to try and balance water/ion conc. cells in this solution would lose water and shrivel up
