Organelles
A detailed description of each organelle’s
structure and function
Recall the similarities and
differences between prokaryotes and
eukaryotes.
What kind of human cells are in
these pictures?
How is each cell’s function related to its structure?

The Cell is Like a Factory
Just like a factory has many departments to
help it run smoothly, a cell has many
compartments, called organelles, that help it
function.
Cell Organelle Jigsaw
Each lab group will research one set of organelles for the
rest of the class.

Visit each station collecting information for each structure
The nucleus is like the boss of the
factory…
Nucleus: Holds the DNA & Controls the
cell’s activities
Nucleolus: A dark region inside the
nucleus. Produces ribosomes
Chromatin: DNA and
proteins inside the
nucleus
Ribosomes: Found in the cytoplasm
and on Rough ER. Assemble proteins
Rough ER: Makes proteins for export;
Provides roadway for proteins
Smooth ER: Makes lipids (fats).
How will you remember the difference
between the Rough ER and the Smooth ER?
The ribosomes are like the machines in the
factory, and the endoplasmic reticulum is
like the conveyor belts…
Golgi apparatus: a complex of flattened
membranes; chemically modifies products
from ER, and ships them to other locations
The Golgi is like the packaging and
shipping department…
The vesicle is like a forklift because it
transports materials inside the cell.
Once they get packaged, the products
can be stored, trashed and recycled or
exported through the cell membrane…
Vacuole: stores
chemicals, food,
waste or water
Lysosome: filled
with digestive
enzymes; digests
and recycle
materials
Cell membrane:
controls what
enters and exits
the cell
The Endomembrane System

Journal of a Protein


Cells manufacture proteins which serve many different
functions within the cell or beyond the cell.
Imagine you are a protein—write journal entries
describing your adventures as you are created and travel
through the cell to your final destination.

Include your relationship with the following structures in your
entries: nucleus, nucleolus, ribosome, rough Er, smooth ER,
Golgi apparatus, vesicles, vacuole, lysosome and cell membrane
Stop and Think:


Or Kahoot questions
What are the similarities between these? What are the
differences?

Draw a Cell



Choose either an animal or plant cell
Copy from any diagram you choose, or draw your own
interpretation
Include all internal structures
Color!!
Hold on to this: It will become part of a larger project!
 Just
like different factories manufacture
different products, the cell will make
different products
The mitochondria and chloroplasts
are the energy producers…
Mitochondria: converts
energy from sugar into
ATP (energy the cell can
use)—Cell Respiration
Chloroplasts: Captures
energy from sun to make
sugar—Photosynthesis
The cytoskeleton is like the building’s
framework…
Cytoskeleton: a network of protein fibers
throughout the inside of the cell; gives it
structure and enables movement.
Microtubules: thin
protein tubes which
organelles travel along.
Microfilaments:
supports the cell’s
shape, and allows it to
move.
Cell Motility
Some cells have external structures that
enable them to move, or to move things
around them!
Some cells have tiny projections, called Cilia
that help to move things around them, like
how a crowd moves a crowd surfer!
…Or their cilia may help to move the
whole cell.
Some other cells have flagella, long, whip-like
structures, to help propel them.
DNA and Chromosomes

DNA: Located in the cell nucleus (for nucleoid for
Prokaryotic) in the chromatin, DNA contains biological
instructions that make each species unique

Chromosomes: thread like molecules that house hereditary
information (found in nucleus)
Cytoplasm

Cytoplasm/cytosol: liquid substance between the cell
membrane and the nucleus that holds the other
organelles
Other parts of the nucleus

Nuclear Envelope: the
two layered membrane that
encases the nucleus.

Nuclear Pore: protein
lined channel that regulates
the transportation of
molecules that can go in and
out of the cell.
(Both similar to cell membrane)
Animal or plant cell extras


Centriole (animal cell only): two centrioles help animal
cells divide during cell division (reproduction), they also
make cytoskeletons (microtubules and microfilaments).
Cell wall (Not in animal cells): provides plant cell with
support and protection.
The Inner Life of a Cell
Cell Analogy Poster


Choose a theme that you can compare to the cell (factory)
Decide which elements of your theme have functions
analogous to cell structures (the factory line is like the rough
ER).


Write a title on your poster “A Plant Cell is Like a Factory”
Use the entire poster to draw your theme and label the
elements with the analogous cell structure
(manager:nucleus)

On the back, write a sentence explaining how each
element of your theme is like a structure in a cell (The
factory line makes circuit breakers like the rough ER makes
proteins)
