Catalyst:
 What
is the difference between prokaryotic
and eukaryotic cells?
 What is the function of the cell membrane?
 If a cell’s nucleus is destroyed, the cell
immediately dies. Using the function of the
nucleus, explain why.
Write in complete sentences!

Objectives

By the end of today, SWBAT…
Describe
the structure and function
of cell organelles related to
energy
Determine if a eukaryotic cell is a
plant or an animal
Mitochondria
The mitochondria
are oval shaped
and have lines
through them
 They produce
energy (ATP) for
the cell

itochondria
Think-Pair-Share
If Higgins were a cell,
what would be the
mitochondrion?
Chloroplast
Chloroplasts are green
ovals, and look like
they contains stacks of
poker chips
 They allow plants to
photosynthesize (use
sunlight to make
sugar)

 Only
cells
found in plant
Chloroplast
Think-Pair-Share
If Higgins were a
cell, what would be
the chloroplast?
Vacuole
Circular storage space
for food and water
 In plant cells, it is
gigantic

VACUOLE
Think-Pair-Share
If Higgins were a
cell, what would be
the vacuole?
Cell Wall
The cell wall is found
outside the cell
membrane in plant
cells
 It holds plant cells in
a rectangular shape

 Only
cells
found in plant
PLANT CELLS
ANIMAL CELLS
Think-Pair-Share
If Higgins were a
cell, what would be
the cell wall?

Organelle Showdown
Choose a partner at your table, and
(using the flash cards) quiz him/her
 Ask difficult questions!
 Keep track of points

 First
student to earn 20 points wins
 I want to know who is the organelle master
at each table!
Whiteboard Practice

Please send someone up from your
group to grab…
One
whiteboard for each person
One dry-erase marker for each person

Behavioral expectations
Take
the work seriously
What is the
function of the
nucleus?
What two organelles that
we discussed today are
only found in plant cells?
This organelle is
MUCH larger in
plants than animals
What is the
function of the
mitochondria?
These types of cells
do not have a
nucleus
Both the chloroplast and
mitochondria make
energy, but different
types. What do each of
them produce?
What would happen
to a cell, if its
vacuole were
destroyed?
This part of the cell is
the reason why
plants are
rectangular in shape
Which of these cells is a plant cell?




Cell #1: cell membrane, nucleus, cytoplasm, vacuole
Cell #2: cell wall, cell membrane, nucleus,
chloroplast, cytoplasm
Cell #3: cell membrane, cytoplasm, DNA floating in
cytoplasm
Cell #4: cell membrane, nucleus, cytoplasm,
mitochondria, vacuole
