Section:
Regulates what enters and leaves the
cell: semi-permeable membrane
Provides protection and support
Cell identification
B. Transportation
1. Diffusion

Movement of molecules from an area of high concentration to
area of low concentration

Movement occurs without any ATP

Eventually looking for equilibrium, or stability
2. Passive Transport

Movement of molecules across a membrane going along its
concentration gradient

Concentration gradient:

the amount of molecules in a certain area where there is
movement from a highly concentrated area to a low
concentrated area
07_11Diffusion_A.html
3. Osmosis
Diffusion of water through a semi-permeable membrane from
area of high concentration to low concentration

Water will move across the membrane until equilibrium has
been reached
4. Questions: Movement of Water
1. If high concentration of water molecules in the cell where
will the water go?
2. If there is a low concentration of water molecules, where will
the molecules go?
3. When equilibrium is reached is the concentration of the
solution in the cell compared to outside of the cell different or
the same?


Isotonic:
The amount of solutes compared to the amount in a cell are equal to
the amount outside the cell
Hypertonic:
The amount of solutes in the solution are high
Hypotonic:
Amount of solutes in a solution are low

were placed in a salt water solution?
What is the preferred solution for a plant
cell?
Why can a red blood cell not live in the
same type of solution as a plant?
D. More Types of Transport
A. Facilitated Diffusion
If a molecule is too large to pass through the membrane, it needs assistance
via protein channel.
B. Active Transport
 Transport of material through the membrane with the use of ATP
 The molecules are going against the concentration gradient
