Eukaryotic Cell
Just like on a sports team or in
an office, cells are composed
of many important
people/organelles that each
fulfill a different role!!!
I give you “The Cell Song”…
Snack factory assembly line
activity ???
I. Cellular Boundaries
A. Cell Wall
1. _______ barrier that
provides support and
2. _________ the plasma
3. Found mostly in plants
(and some bacteria)
II. Cell Control
A. __________
1. Control center
a. Contains blueprints to
make proteins (DNA)
b. The other organelles
depend on specific proteins
to do ____________
II. Cell Control
2. Contains ________
(DNA) which gives
instructions for making
II. Cell Control
B. Nucleolus

D. ___________
1. Clear, gelatinous fluid
that contains all of the
organelles except the
Let’s continue to follow the
trail of the protein!!
III. Assembly, Transport & Storage
A. _________________ (ER)
1. Rough ER—Ribosomes
make proteins here
2. Smooth ER—The proteins
undergo chemical reactions
a. ________ & storage
of lipids

3. The ER is a highly _____
a. Allows for a lot of
work to be done in a
small amount of
III. Assembly, Transport & Storage
B. ____________________
1. Sorts proteins into
packages called vesicles
(A.K.A. The Post Office)
2. Sends _________ to the
appropriate destination in the
4. Looks like a pancake stack
& syrup drops (vesicles)

materials in the cell
a. food
b. __________
c. water
d. ________________
III. Assembly, Transport & Storage
2. Animal cells usually do
NOT have _______. If so,
they are very small.
3. Plant cells usually have one
______ vacuole.
III. Assembly, Transport & Storage
D. __________
1. Digest worn out cell parts,
food particles, viruses, etc.
2. Lysosomes contain enzymes
a. The membrane around
the lysosome protects the
rest of the cell from being
III. Assembly, Transport & Storage
b. The lysosome _____- with
a vacuole and releases the
enzymes into the vacuole to
digest its contents.
Where does a cell get the
energy to make these
Stay tuned to find out…
IV. Energy Transformers

accordion folds.
IV. Energy Transformers
3. The number of
mitochondria depends on the
______ of the particular cell
a. Liver cell & muscle cells
have ________ mitocondria
b. Cellular respiration
occurs here
Can cells move???
You bet! Here’s how…
V. Support & Locomotion
A. ______________

microfilaments (solid) make up
a framework for cell shape and
movement of materials
V. Support & Locomotion
B. _________
1. Short, hair-like projections
that cover the cell surface.
