Organelles...
Golgi Apparatus
• The Golgi Apparatus is very similar to the ER in
both function and appearance.
• It is responsible for transporting proteins or
lipids made by the ER to various parts of the
cell.
Golgi Apparatus
Golgi Apparatus
• The Golgi acts like a Post Office.
Golgi Apparatus
• The Golgi acts like a Post Office.
• It receives proteins, “addresses” them by
attaching different carbohydrates, and then
delivers them to the correct part of the cell.
Golgi Apparatus
• The Golgi acts like a Post Office.
• The Golgi is very important in ensuring that
proteins get delivered to the correct area of
the cell.
Play-Doh
• Create the Golgi Apparatus
• Place it inside your cell.
Vesicles
• Vesicles are responsible for transporting
substances throughout the cell
(like the Post Office’s Trucks.)
• They are spherical organelles, surrounded by
their own membrane layer.

What are cell membranes made
out of?

Phospholipids
Vesicles
• Two important vesicles are:
– Lysosomes
– Peroxisomes
Lysosomes
• Lysosomes are vesicles that form from the
Gogli Apparatus.
• Lysosomes are the cell’s “clean up crew.”
Lysosomes
• Lysosomes are vesicles that form from the
Gogli Apparatus.
• Lysosomes are the cell’s “clean up crew.”
• These vesicles contain digestive enzymes that
break down biological molecules and
organelles.
Lysosomes
• Lysosomes in the liver break down
carbohydrates in order to release sugar into
the blood stream
• White blood cells use lysosomes to break
down invading bacteria cells.
Lysosomes
• Lysosomes are also responsible for breaking
down cells when it is time for the cell to die.
• This function is very important in maintaining
the health of the organism.
Peroxisomes
• Peroxisomes are also vesicles that contain
digestive enzymes.
• These vesicles, however, are not produced by
the Golgi Apparatus.
Peroxisomes
• Peroxisomes are responsible for neutralizing
compounds which would normally harm the body.
• Peroxisomes are help detoxify alcohol and other
drugs within the body.
Play-Doh
• Create some vesicles:
– A Lysosome
– A Peroxisome
(make them different colors)
• Place them inside your cell.
Cytoskeleton
• The cytoskeleton gives
shape to the cell.
• It is composed of a
network of crisscrossing
tubes and filaments in
the cytoplasm.
Cytoskeleton
• The cytoskeleton is composed of three specific
elements:
– Microtubules
– Microfilaments
– Intermediate filaments
Play-Doh
• Create the cytoskeleton
(crisscrossing filaments in the cytoplasm)
• Place them inside your cell.
Cilia and Flagella
• Many cells have either cilia or flagella to help
them move.
Cilia and Flagella
• Cilia – hair-like
structures on the
surface of the cell that
assist in movement.
• Cilia are short and
present in great
numbers.
Cilia and Flagella
• Flagella – tail-like structure on the surface of a
cell that assists in movement.
• Flagella are longer than cilia and are far less
numerous when found on cells.
Play-Doh
• Create both cilia and flagella for your cell
• Place them on the outside of your cell
1) Our bodies treat alcohol as a poison.

who frequently abuses alcohol to have a higher
number of __________ than someone who does
not drink alcohol.
