Aim: How does
Osmosis and Diffusion
compare?
What is the diffusion of
water called?
Osmosis
What is meant by concentration?
The amount of a
substance
Distilled water
100% pure water
What happens
when we add a
SOLUTE like
salt or sugar?
Solvent: The liquid
(ex. Water)
Solute: The solid added
to the liquid (Salt/sugar)
Concentration Differences:
1)
A 90% salt solution vs. a 20% salt
solution
Which solution has more salt particles?
Which solution has more water molecules?
2) A 60% salt solution vs. 80% salt
solution?
Which container has a greater
concentration of water molecules?
= Solute (salt)
= Solvent (water)
Which container has a greater
concentration of solute molecules?
In which direction is osmosis going
to occur?
= Solute (sugar)
= Solvent (water)
Selectively Permeable
Why does this happen?
Why are the water molecules
diffusing to the left?
Water molecules are red
Why does water go in and out
of the cell?
To in
maintain
EQUILIBRIUM of
Solutions
whichDYNAMIC
the concentrations
solute are equal are said to be ISOTONIC
What happens to an animal
cell if it is surrounded by a
high concentration of water?
The solution with the higher concentration of water
Is said to be HYPOTONIC
What happens to an animal
cell if it is surrounded by a
low concentration of water?
The solution with the lower concentration of water is
said to be HYPERTONIC
What about Plant Cells?
Plant cell placed in
a hypertonic
solution
Plant cell placed in a
hypotonic solution
Will osmosis happen?
In which direction will
osmosis happen?
How is osmosis a form of
passive transport?
Osmosis is the movement of water from
an area of high concentration to an
area of low concentration. No ATP
