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.

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

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

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?
