Structure of the Cell
Organelles and their
functions
We’ll Explore the Cell Parts by
doing the following:
 Stating
the organelle
 Stating what the organelle is like by
comparing to parts in a city
 Draw the organelle
 State where it is found (animal cell, plant
cell or both)
Cell Wall




A rigid layer of nonliving
material that surrounds
the cell membrane.
Protects and supports the
cell.
Found in plants and some
other organisms.
Like a wall surrounding a
city.
Cell Membrane

Like the gate keeper
of a city.
 Controls what comes
into and leaves the
cell.
 Found in plant and
animal cells.
 Consists of a lipid
bilayer.
Nucleus

Control center of the
cell (directs all cell
activity)
 Contains DNA
 Like city hall in a city
 Found in both plant
and animal cells
Endoplasmic Reticulum

A passageway for
which proteins and
other materials are
carried throughout the
cell.
 Found in both plant
and animal cells
 Like a delivery truck
in a city.
Golgi Body



Receives and packages
proteins and other
materials from the E. R.
for distribution throughout
the cell.
Like the post office in a
city.
Found in both plant and
animal cells.
Mitochondria

Produces energy for
the cell.
 Like a power plant in
a city.
 Found in both plant
and animal cells.
 More active cells
contain more
mitochondria.
Ribosomes

Protein producing
organelles found in
the cytoplasm and on
parts of the E. R.
 Like factories in a city.
 Found in both plant
and animal cells.
Ribosomes on the E. R.
Cytoplasm

Gel-like matrix within
the cell.
 Like roadways within
a city.
 Acts as a medium
within which
molecules can move
through the cell.
lysosome

A small round
structure containing
chemicals that break
down particles.
 Like the refuse
collector in a city.
 Found in plant and
animal cells.
Chloroplast

Captures energy from
sunlight and uses it to
produce food.
 Like solar panels in a
city.
 Found in plants and
some other
organisms.
Vacuole

A sac inside the cell
that acts as a storage
area.
 Like a warehouse in a
city.
 Found in both plant
and animal cells but
generally larger in
plant cells.
