3
What are lipids and proteins?
The 2 main components of the cell membrane.

• Row 1, Col 1

4
Movement of molecules from high to low
concentration.
Define diffusion

• 1,2

5
The movement of molecules from low to high
concentration which requires energy.
Define active transport

• 1,3

6
The membrane only allows certain molecules into
or out of the cell (but keeps others out).
Define selective permeability

• 1,4

7
It got much bigger due to water diffusing into
the egg. Hypotonic.
TWO PART QUESTION Explain what happened to the
egg In exciting osmosis when we placed it
into Distilled water? Was the egg in a hypotonic,
Hypertonic or isotonic solution?

• 2,1

8
Osmosis
The diffusion of water is called

• 2,2

9
Movement of molecules that can not diffuse
through the membrane or protein channels and must
be brought into the cell using energy
Define endocytosis

• 2,3

10
Non-polar small molecules.
What type of molecule Easily diffuses through The
cell membrane.

• 2,4

11
What is hypotonic?
An animal cell is placed in pure water. The
pure water is considered what type of solution?

• 3,1

12
High to low.
Diffusion moves things from ____ to ____
concentration.

• 3,2

13
The movement of molecules out of a cell
requires energy.
Define exocytosis

• 3,3

14
What is a hypotonic solution
What type of solution is best for a plant cell
to be placed in?

• 3,4

15
The greater the concentration of solute, the
faster the rate of passive transport.
What is the correlation between Solute
Concentration and the rate of Passive
transport?

• 4,1

16
Hypertonic solution. The water will move into a
cell.
A cell surrounded by WICKED SALTY Water is in a
_____ (hypo, hyper or Isotonic) solution. In
which direction will the water Move?

• 4,2

17
Energy
Unlike, Passive transport, this is required for
active transport

• 4,3

18
In Facilitated diffusion, proteins help molecules
that are too big or too charge move from H --gt L
through the membrane. In Diffusion, molecules
can move through the lipid bilayer with out the
help of the proteins.
Contrast Facilitated diffusion diffusion

• 4,4

19
The iodine diffused because it is a smaller
molecules the starch did not b/c it is a large
molecule.
Explain what diffused What did not diffuse in
the Starch iodine experiment why?

• 5,1

20
The solution is hypertonic to the cell. There are
more solutes outside of the cell than inside.
A cell shrivels up. What Type of solution is
the cell Immersed in? Contrast the
solutes Concentration inside outside Of the
cell.

• 5,2

21
Pinocytosis
The movement of water into a cell is called

• 5,3

22
The phosphate heads are hydrophilic the lipid
tails are Hydrophobic.
Which part of the cell membrane Is hydrophilic
which Hydrophobic?

• 5,4
