Eukaryotic Cell
Structure
7.3
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
protection
2. _________ the plasma
membrane
3. Found mostly in plants
(and some bacteria)
II. Cell Control

1. Control center
a. Contains blueprints to
make proteins (DNA)
b. The other organelles
depend on specific proteins
to do ____________

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
III. Assembly, Transport & Storage
3. The ER is a highly _____
membrane
a. Allows for a lot of
work to be done in a
small amount of
space
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
cell
4. Looks like a pancake stack
& syrup drops (vesicles)
III. Assembly, Transport & Storage
C. ___________
1. Temporary storage of
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
proteins???
Stay tuned to find out…
IV. Energy Transformers
A. Chloroplasts
1. Capture ______ and
convert it to chemical energy
(food)
2. Found mostly in ____ cells
IV. Energy Transformers
3. Type of _______
a. a group of plant organelles
used for _______ of food or
pigments
b. Chloroplasts store the
green pigment chlorophyll
1) Traps the sunlight
needed for photosynthesis
IV. Energy Transformers
B. _____________
1. Breaks down the _____ into a
form of energy that the cell can use
(ATP)
a. This process is called
_____________________
2. Folded membranes allow for a lot
of work to be done in a small space
a. Looks like kidney bean with
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. ______________
1. Support structure of the cell
a. Organelles don’t just
float around in the cell!
b. _________ (hollow) and
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.
2. Move like the oars of a row
boat to propel the cell forward
or bring things to the cell.
V. Support & Locomotion
C. _________
1. Long tail-like projections on
the cell
2. Usually a cell only has one or
two flagella
3. Makes a ________ motion
VI. Other

1. Play an important role in cell
division (mitosis)
a) _____ fibers come from
centrioles
2. Found only in ______ cells
and most protists
