Catalyst: What is the BIG 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.

FIRST FIVE.

Catalyst Energy Organelles Energy Organelles Challenge Independent Practice EQ

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

REMEMBER:

Organelles are the small parts of a cell

We have already learned about… Nucleus Cytoplasm Cell membrane

Mitochondria

The mitochondria are oval shaped and have lines through them

They produce energy (ATP) for the cell

Mitochondria

Write – Pair – Share

Create an analogy:

If Helen Cox was 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

Write – Pair – Share

Create an analogy:

If Helen Cox was a cell, what would be the chloroplast?

Vacuole

Circular storage space for food and water

In plant cells, it is gigantic

VACUOLE

Write – Pair – Share

Create an analogy:

If Helen Cox was 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

REMEMBER OUR OBJECTIVES:

Describe the structure and function of cell organelles related to energy

Determine if a eukaryotic cell is a plant or an animal

Whiteboard Practice

Please send someone up from your group to grab… One whiteboard for each person One dry-erase marker for each person Two erasers for your group

Behavioral expectations Take the work seriously Stay focused and on task

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?

(throwback!)

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?

OPTIONS EXPLAIN HOW YOU KNOW THIS IS OR IS NOT A PLANT

CELLCell #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

(throwback!)

Using your knowledge of the characteristics of life, explain why the parts of cells are alive or not alive.
