									Prokaryotic and Eukaryotic Cells

    Catalyst (REMEMBER: MR. GORE!)
     Are green, growing leaves alive?
      Why/why not?
     Are computers alive? Why/why not?
     Which phone is older?
      Explain how you know.

FIRST FIVE.
Agenda
   Catalyst
   What is Life? review
   Prokaryotic vs. Eukaryotic cells
   Throw Your Hands in the Air
   EQ

EXTRA CREDIT HOMEWORK: Bring in one
    100 pack of 3x5 index cards for +2 points on your
    unit test!
To be alive, you must have ALL:

                 Metabolism
                 Reproduction
                 Growth
                 Organization
                 Response
                 Evolution
Objectives

   By the end of today, SWBAT…
    Compare   prokaryotic and eukaryotic
     cells
    Describe the role of DNA, the cell
     membrane, cytoplasm, and the
     nucleus in the cell
Why do we care about cells?

 You are alive
 Parts of you are alive!

 Parts of those parts are alive!

 Where does it end?

 The cell!

     The cell is the smallest form of life
     ALL living organisms are made of cells
Human Red Blood Cells
White Blood Cell Attacking Bacteria
Human Sperm Cell
Human Egg Cell
What makes them different?

   Key Point #1: The function of a cell
    (what it does) is determined by its
    structure (what it is made of)
    DNA (deoxyribonucleic acid) is the
      genetic code that instructs the cell
      how to run (it’s what makes you
      “you”)
    Organelle: Part of a cell
Cell membrane

 The cell membrane
  is a thin, flexible
  barrier around the
  cell
 It controls what goes
  in and out of the cell
 All cells have this
Cytoplasm

 The cytoplasm is
  everything inside of
  the cell membrane
 The cytoplasm
  contains all the cell
  organelles
 All cells have this
Nucleus

   Nucleus holds DNA
    and controls the cell’s
    activities
     The cell’s own mini-
      brain
   The nucleus has its
    own special
    membrane
So we have some organelles…
   To help you remember the function of each, create
    an analogy in your notes.

   Compare each cell organelle to a part of Helen
    Cox.

   The (cell organelle) is like a (make a comparison)
    because it ______________________________.
What makes them different?

   Key Point #2: Prokaryotic and
    eukaryotic cells have different
    structures
    Eukaryotic cells
   Eukaryotic cells have a
    nucleus
     Membrane-bound
      organelles
     All multi-celled
      organisms are
      eukaryotes
     So all PLANTS and
      ANIMALS are
      eukaryotes
     Can be single-celled
    Prokaryotic cells
   DNA is
    floating in the
    cytoplasm
    Always
     single-celled
     organisms

Quick Recap

            Eukaryotic?      Prokaryotic?
Cell        Yes              Yes
Membrane
Cytoplasm   Yes              Yes
Nucleus     Yes              No
DNA         Yes, inside of   Yes, floating
            nucleus          in cytoplasm
Study Time

 Take 5 minutes to study your note
  cards.
 If you realize that you don’t understand

  what you wrote down…
    Take notes in your own words!
    Ask your group members
    Raise your hand and ask me for help
“Throw your hands in the aaaaair” (GP)

   First round
 Discuss    in groups
   Second round
 Try    on your own
 ROUND
  ONE
(Groups)
Where all cell
organelles are
found
Controls everything
 that happens in the
 cell.
Prokaryote or Eukaryote?
Found on the edge of
 the cell.
Prokaryote or Eukaryote?
Everything inside of
 the cell membrane.
This cell is single-
 celled, its traits are
 controlled by DNA,
 and has a nucleus
  ROUND
    TWO
(Individual)
Missing in
prokaryotes.
All plants and
 animals are this
 type of cell
ALL CELLS have these
 TWO things. (Hold
 up both cards.)
Decides what gets to
 go into the cell, and
 what has to leave.
In eukaryotes, DNA is
 found here.
Prokaryote or Eukaryote?
A Bloopie is a single-celled
 organism, has a flagellum,
 and membrane-bound
 organelles. What type of
 cell does it have?
Which of the following is true?
1.   What enters/leaves the cell is controlled by “A”
2.   The presence of “B” makes this a eukaryotic cell
3.   The presence of “B” makes this a prokaryotic cell
4.   “C” is found in ALL cells  B

Quiz your partner

 With the person next to you, use the flash
  cards to quiz him/her
 Be difficult!

     Ask anything we have learned today
     Don’t take an answer unless it is perfect
     What we have learned today is fundamental to
      everything else we will learn about the cell… so
      get it right!!!
Exit Questions        Complete sentences!
                         Don’t talk!


1. Describe the differences between
   eukaryotic and prokaryotic cells.
   (Include at least two.)
2. Describe what TWO out of these
   three things do in the cell: cell
   membrane, cytoplasm, nucleus
