Cell Organelle Review
¡ For each clue…
¡  THINK: What organelle could this be?
¡  Turn-and-Talk to your neighbor:

Finish Notes from Yesterday
¡  Take out your “Cells! Notes” from yesterday.

¡  We will be starting on the back, “VI. Cell
movement & Classification”
Cell Movement and
Classification
Cilia
¡ Function: Small,
hair-like
structures that
vibrate to help the
cell move
¡ Analogy: Small
vibrating hairs
Flagella
Function: Whiplike tail that
helps the cell
move
Analogy: Whip

Pseudopodia
“Pseudo” = false
Pseudopodia
“pod”= foot
¡ Means “false
foot”
¡ Function:
moves the cell
by RESHAPING
itself
Analogy: the blob

II. Classification of Cells
¡ 2 classifications
¡ Prokaryotic and Eukaryotic
Definitions
¡ Pro= before
¡ Eu= true
¡ Kary = nucleus
¡ Prokaryote= before nucleus
¡  It is a cell that does not contain a nucleus
¡ Eukaryote = True nucleus
¡  Type of cell that contains a nucleus and
membrane bound organelles
Thought Question
¡ Looking at your notes about cell organelles,
and the diagrams of the plant, animal, and
bacterial cells…
¡  Which of these types of cells are prokaryotes?
¡  Which are eukaryotes?
¡  What evidence do you have to support your choice?
Animal and Plant Cells
THE EUKARYOTES
Prokaryotic Cells
¡ Prokaryotic cells are generally less
complex than eukaryotic cells.
¡ They do not contain as many organelles,
but they are still considered a cell
¡  They contain-
¡  Cell wall
¡  Cell membrane
¡  Ribosomes
¡  Cytoplasm
¡  DNA
Cell Organelle Stations
¡  You will further explore cell organelles by completing station
activities. Stay with your group at each of the 8 stations. You
will have 5 minutes at each station—stay on task!
¡  DO NOT write on any of the cards, models, or booklets!!

¡  If you finish early at a station, quiz the other group members
about the functions of organelles. Ask, "What is the function of
the ______?" to the others.
