Animal Cell
Cytoplasm
Nucleolus
Nucleus
Ribosomes
Cell Membrane
Mitochondria
Rough Endoplasmic
Reticulum
Golgi Bodies
Smooth Endoplasmic
Reticulum
Eukaryotic Cell Organelles and
Function
Cell Membrane
Nickname: “The Screen Door”
Function:




Hold and protect the cell
Control the movement of materials into and
out of the cell
Eukaryotic Cell Organelles and
Function
Nucleus



Nickname: “The Control Center”
Function: Holds the DNA
Parts:
1.
Nucleolus: dark
spot in the middle
of the nucleus that
helps make
ribosomes
Eukaryotic Cell Organelles and
Function



DNA
Nickname: “The Info”
Function

hereditary material that is passed on to
you from your parents and is kept safe
inside the Nucleus
Eukaryotic Cell Organelles and
Function
Cytoplasm


Nickname: “Jell-O”
Function: A watery, gel-like material in
which cell parts move
Eukaryotic Cell Organelles and
Function
Vesicle
Nickname: “The Bag”
Function:



Small membrane-enclosed organelle that can
store or transport substances
Eukaryotic Cell Organelles and
Function
Ribosomes






Nickname: “The Factory”
Function: makes proteins
Made in Nucleolus
Found in all cells
NOT membrane bound
Smallest & most abundant
organelle in the cell
Eukaryotic Cell Organelles and
Function
Endoplasmic Reticulum (ER)



Nickname: “The Highway”
Function: The internal delivery system of
the cell
There are 2
types: Rough &
Smooth
Eukaryotic Cell Organelles and
Function
Golgi Bodies (Golgi Complex)



Nickname: “The Post Office”
Function: packages and transports
materials to different location
inside/outside of the cell
Appearance: stack of pancakes
Eukaryotic Cell Organelles and
Function
Lysosomes: circular shape but larger
than ribosomes


Nickname: “The Trash Man”
Function: to break down food into
particles the rest of the cell can use and
to destroy old cells
Eukaryotic Cell Organelles and
Function
Mitochondria


Nickname: “The Powerhouse”
Function: Breaks down food molecules to
release energy for the cells

Section:
Eukaryotic Cell Organelles and
Function

Cell Wall


Nickname: “The Fence”
Function

Tough, rigid structure found outside of cell
membrane that provide support for plants and
fungi
Eukaryotic Cell Organelles and
Function
Chloroplasts
Nickname: “The Hulk”
Function:



traps energy from the sun to produce food
for the plant cell

Green in color because of chlorophyll, which is
a green pigment
Eukaryotic Cell Organelles and
Function
Vacuoles


Nickname: “The Water Tower”
Function: stores water & give support

This is what makes lettuce crisp

When there is no water, the plant wilts

They are also found in animal cells, but are
smaller
PROKARYOTIC CELLS
Bacteria Cell
Only in Prokaryotic Cells
Gelatin-Like Capsule:
Nick Name: “The Armor”
Function: outer covering protects the cell
when it is eaten by other organisms



Allows Bacteria to survive and be dormant for
many years until the conditions are right
Only in Prokaryotic Cells
Flagellum:
Nickname: “The tail”
Function:




Helps the cell move
Used as a sensory organ
