Agenda:
•Bell-ringer
•Objective
•Finish “Multicellular and
Unicellular” Venn diagram
•Prokaryotic and Eukaryotic
reading/jig-saw activity
•“Prokaryotic and Eukaryotic”
notes (if time)

Title page 20, Multi-cellular and Uni-cellular
Venn Diagram
Directions:
• Complete the Venn diagram to identify the
similarities and differences between multicellular
and unicellular Organisms.
• Use page 19/21, if you need help coming up with
similarities and differences
• Add 2 facts that relate to the unicellular and
multicellular organism reading.
• Paste the Venn diagram unto page 20.
Eukaryotic and Prokaryotic Reading/Jig-saw Activity
1. Mrs. Plaza and myself are going to divide the class. One
half of you will read about Eukaryotic cells with Mrs. Plaza,
and the other half will read about Prokaryotic cells with
me.
2. Use your paper to underline important information about
your type of cell; you can even highlight.
3. After the reading, you will find a student who has the other
type of cell, and you will share the information that you
have read. Then, they will share their information that they
have read.
4. Once you have finished teaching each other about your
cells, see me about a worksheet that you and your partner
will complete together. *It’s for points, make sure you
complete it!!!*
Tuesday, Sept. 29th – 4th period

yesterday, and get out your

Prokaryotic Cells
Eukaryotic Cells
•These are single celled organisms.
•They have no nucleus, but have DNA.
•Their DNA is scattered throughout the
cell.
•They are very small even under a
microscope.
•These are the largest cells.
•All living things that are not bacteria or
archaea are made of eukaryotic cells.
•They have a nucleus with DNA inside.
Examples: Bacteria and Archaea
Examples: Animals, plants, and fungi

Directions:
1. Fold your “Cell Structures: Cell Organelle Graphic Organizer” like a
hamburger. It should flip open like a book with the title on the front
and “Glue Here” on the back.
2. Apply glue to the “Glue Here” box. The best way to get the sheet to
stick is to trace over the “Glue Here” box and then make an “X”
through the center of the box.
3. To place in your notebook –line up the folded edge of your sheet
with the red margin line on the left to ensure it is straight. To make
sure the page doesn’t stick out the bottom of your notebook, line up
the top of the sheet with the top blue line- press firmly to glue in
place.
4. Now, you have your sheet on the right side of your notebook, you
*First entry on the sheet*
Cell Theory tells us…
1. All living things are
made of cells.
2. Cells are the smallest
working units of all
living things.
3. Cells come from preexisting cells through
cell division.

What is a Cell?
A cell is the smallest unit that is capable of
performing life functions – i.e. has all of the
characteristics of living things.
Notice how the shape of the cell determines what its function is…

Characteristics of
Prokaryotic Cells
• Simple, unicellular organisms
• Do not have membrane-bound
organelles
• Bacteria ONLY!
• Includes Kingdoms Eubacteria
and Archaebacteria
• We like to say “PRO?” “NO!”…
meaning NO nucleus, NO
organelles
© Getting Nerdy, LLC
Characteristics of
Eukaryotic Cells
• Complex organisms - most living
things
• Can be unicellular or multicellular
• Contain organelles surrounded by
membranes
• For this, We like to say “EU
(YOU)?” “TRUE!”… meaning TRUE
nucleus, TRUE organelles
