Do Now Review
• Answer: TO MOVE!
• Tiny, one-celled organisms don’t have legs like we do.
But they need to be able to move, either to eat or to
get close to the sun to make their own food.
• So, since they don’t have legs,
they need another way to move!

8I: Prokaryotes v Eukaryotes
Cellular Movement
Discussion
Homework: #40
S.O.T.D.
Today’s Objectives
1 . Scientists will be able to support
ideas about cell movement with a
demonstration.
2. Speaking: Students will describe the
different types of cellular
movement.
How I know you’ve got it…
When you can describe the different types of
movement and what the organelles are that
help organisms move, you’ve got it!
Compare and Contrast
• The back of your worksheet has a prokaryotic cell and a
eukaryotic cell. Time to make some observations!
• Use the graphic organizer to write similarities and differences.
• Think-Pair-Share! 3 minutes alone, 2 with partner.
Prokaryotic Cell
Eukaryotic Cells
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Wanted RAFT
You will be creating a RAFT according to the directions. Follow
the expectations to get the A+ today. Let’s read the directions
together!
You will need to use the books to help you out with the
information about these two cell types!
Prokaryotic Cell
Eukaryotic Cells
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Practice: Hands Up!
•
I’m going to show you a cell.
•
Your job is to tell me whether it’s:
– A Prokaryotic Cell (1 hand up)
– A Eukaryotic Cell (2 hands up)
•
So everyone has time to think,
DO NOT PUT UP YOUR CARDS OR
HANDS UNTIL I SAY GO.
•
Expectations: silent, everyone tries!
Today’s Objective: Scientists will be able to explain the difference between
prokaryotic and eukaryotic cells.
Prokaryote (1 Hand)
or Eukaryote (2 Hands)?
Prokaryote
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Prokaryote (1 Hand)
or Eukaryote (2 Hands)?
Eukaryote
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Prokaryote (1 Hand)
or Eukaryote (2 Hands)?
Eukaryote
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Prokaryote (1 Hand)
or Eukaryote (2 Hands)?
Prokaryote
Today’s Objective: Scientists will be able to compare and contrast prokaryotic
and eukaryotic cells.
Prokaryotes vs. Eukaryotes
• Bacteria and other small, simple organisms have prokaryotic cells.
– Another way to say this is that bacteria are prokaryotes.
• Animals (such as humans), plants and other large, complicated
organisms have eukaryotic cells.
– Another way to say this is that animals are eukaryotes.
Prokaryotic Cell
Eukaryotic Cells
Today’s Objective: Scientists will be able to compare and contrast prokaryotic and
eukaryotic cells.
Prokaryotic Cells (Prokaryotes)
• Prokaryotic Cells:
– Are simple cells.
– Do NOT have a nucleus to hold their DNA
(the body’s blueprints).
– Do NOT have most organelles
(for example, mitochondria
or lysosomes).
Today’s Objective: Scientists will be able to explain the difference between
prokaryotic and eukaryotic cells.
#1: Flagella (One = Flagellum)
What do you
observe?
Video 1: Flagella
What does it
look like?
A flagellum looks like a very long hair, or like a whip.
How does it
work?
It moves the cell by spinning,
like a plane’s propeller.
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
#2: Cilia
What do you
Play Video 2 Cilia
observe?
What does it
look like?
Cilia look like tiny hairs
covering a cell.
How does it
work?
They work together like oars,
moving in a wave to help the
cell move.
cilia
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
#3: Pseudopods
What do you
Play Video 3 Pseudopods
observe?
What does it
look like?
Pseudopods look like arms reaching out
from the cell.
How does it
work?
Cytoplasm flows to one part of the cell, making a
temporary arm that pulls the cell along.
pseudopod
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
Practice: Hands Up!
•
I’m going to show you a cell that can move.
•
Your job is to tell me whether it’s moving with a:
– Flagellum (1 arm up)
– Cilia (wiggle fingers)
– Pseudopod (reach out)
•
So everyone has time to think,
DO NOT PUT UP YOUR
HANDS UNTIL I SAY GO.
•
Expectations: silent, everyone tries!

Ever Heard of this Show?
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
So You Think You Can Move!
• You are about to go on the new hit show, “So You Think You
Can Move!” So, you need some new dance moves!
• For each way a cell can move –
by using flagella, cilia or pseudopods – you must:
– Describe the dance move.
– Draw the dance move.
– Explain why the dance move makes
sense for that organelle.
(It might help to begin, “This dance
move makes sense because …”)
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
Example
• Describe: To do the pseudopod, you reach out with your arms
and pull yourself along. Come on, do it with me!
• Draw:
• Explain: This dance move makes tons
of sense because pseudopods are
temporary arms of cytoplasm that
pull the cell along.
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
So You Think You Can Move!
• You have 10 minutes to work on your dances.
What you don’t finish is homework.
• Each column will start with a different dance.
• When time is up, one person will TEACH each dance.
• To get a 4.0 class performance grade for today:
Today’s Objective: Scientists will be able to support ideas about cell
movement with a dance.
HW: #40
Careful, it has a front and back!

make their food through photosynthesis.
