For each picture say what type of
solution it is and where water will go

Passive
transport
Cornell notes in your notebook
Passive transport

Requires NO energy- the body
is trying to reach homeostasis
•
•
Solutes move DOWN the
concentration gradient
From high concentration to low
concentration
1. Osmosis
WATER moving DOWN the concentration
gradient
 Water is polar, so it goes through the
phospholipid bilayer

2. Diffusion
 Movement
of a small particle
DOWN the concentration
gradient
Ex:
Diffusion
in blood:
exchange CO2
and O2
3. Facilitated diffusion
 Movement
of a big particle DOWN the
concentration gradient with the help
of a protein in the plasma membrane
 Ex:
glucose
