Download 10% SALT

Goal:
To understand
transport through a membrane.
• Sit down facing the screen
• Take out Guided Notes
• Take out pen or pencil
• Examples: Diffusion & Facilitative Diffusion
• Movement of substances from
an area of higher concentrations
to an area of lesser concentrations.
NO ENERGY is needed!!!

• Example: Osmosis
• Movement of water from an area of
high concentrations to an area
of lesser concentrations.

– Movement of substances from an area of
lesser concentrations to an area of greater
concentrations.
– Requires ENERGY!
• Exocytosis
Process in which the cell expels
large particles (waste matter)
out of the cell. Exo = exit
• Endocytosis
Process in which the cell
engulfs large particles (food)
into the cell.
Homeostasis
The cell membrane, using passive and active
transport, determines what gets into or out of
the cell.
The selective flow of material helps the cell to
maintain constant internal conditions: called
Homeostasis.
Solution
• a solution is a
homogeneous mixture
composed of two parts.
• a common example is a
solid, such as salt or
sugar, dissolved in water.
• Solventthe part that does the
dissolving, usually larger.
• solutethe part that dissolves,
usually smaller.
Cells in 3 Types of Solutions
1. Isotonic(equal)
2. Hypotonic(less)
3. Hypertonic(more)
• When talking about types
of solution, always think
about the solution outside
the cell.
• Ask the question does the
solution have an equal,
more or less solute outside
the cell than inside.
• Iso-Hypo-Hyper?????
• Then figure out if the
there is more or less water
outside the cell than
inside.
• Osmosis - water moves
from greater to lesser
Isotonic
1.
Isotonic literally translates
to equal tension.
2.
Solute concentration of
solution outside the cell is
equal to that inside the cell.
Iso-Hypo-Hyper?????
3.
Water concentration is equal
inside & outside the cell
4.
No net water movement
Hypertonic Solution
1. Solute concentration of 40% salt
solution is higher outside 60% water
the cell than inside.
2. Hyper = more (think
hyperactive).
3. Less water outside the
cell than inside.
4. Water moves out of cell
into solution･ Cell shrinks

water
Hypotonic
1. Hypo = less
Think HIPPO = cell gets large
2. Solute concentration of solution
is lower than the solute inside
the cell.
3. More water outside the cell.
4. Water moves into cell from
solution.
5. Cell expands (and may burst)
