Catalyst: What can plants do that animals
can’t? 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.

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
Mitochondria
Think-Pair-Share
If West Jeff 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 found in plant
cells
Chloroplast
Think-Pair-Share
If West Jeff 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 West Jeff 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 found in
plant cells
PLANT CELLS
ANIMAL CELLS
Think-Pair-Share
If West Jeff 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
Which organelle is this arrow pointing to? What is its function?

Plant cell or animal cell?
Plant cell or animal cell?
