3.2 Cell Organelles

Eukaryotic Cell Posters: Organelles pg. 73-79 in textbook

1. Determine whether you are going to make a plant or animal cell

2. Draw the outline of your cell on your poster 3. Out of construction paper- construct organelles

(using a different color for each type of organelle)

4. Label each organelle5. Write the function of each type of organelle

3.2 Cell Organelles

Mitochondria

• Convert molecules from the food you eat into usable energy

• Powerhouse of the cell

Rough E.R.

Example

3.2 Cell Organelles

Cell City Directions

1. Determine what parts/jobs of a city are similar to that organelles function? •Ex: Nucleus is like City Hall

*Organelles may have more than one job (Ex: lysosomes have many cityjobs/locations)Include:ChloroplastNucleusLysosomeVacuoleRough E.R. Golgi apparatusCell WallCell MembraneCytoplasmMitochondriaRibosomes

2. Make a rough draft of your city on a lined sheet of paper

3. Final Draft: On a poster paper provided by Mrs. McCobb, draw/cut-out your city parts and organize them on the poster like a real city would be organized. Make sure it is clearly written and drawn.

4. Label each part of the city and underneath it in parentheses label the organelle it represents. Ex. City Hall (nucleus)

Topic: 3.2 Cell Organelles

Essential Question:

Compare: What similarities do mitochondria and chloroplasts share?

2.1 Atoms, Ions, and Molecules

Compare: What similarities do mitochondria and chloroplasts share?

3.2 Cell Organelles

Key Concept: Eukaryotic Cells share many similarities

3.2 Cell Organelles

Please get 12 colors

You can mix/match highlighters/crayons/colored pencils/pens

As we go through the function of each of the organelles, you will color code:

The organelle on your plant and animal cell on pg. 24

Your vocabulary words on pg. 25

Can you find some similarities????

3.2 Cell Organelles

Like your body, eukaryotic cells are highly organized structures.

3.2 Cell Organelles

•Skin:

• Receives sensory information (touch)

• Protects

•Intestines:

• Digest food

•Kidneys:

• Filter waste

•Bones:

• Protect and support other organs

3.2 Cell Organelles

•Cell membrane:

• Separates interior material from outside environment

• Selectively permeable (only certain things can move in and out)

How can we compare the cell membrane to our skin?

3.2 Cell Organelles

• The cytoskeleton is made of small protein subunits that form long threads, or fibers, that crisscross the ENTIRE cell.

3.2 Cell Organelles

– provides strength, shape, and support– helps position and transport organelles

– assists in cell division

How can we compare the Cytoskeleton to our human Skeleton?

3.2 Cell Organelles

• *The nucleus stores and protects genetic information or DNA (deoxyribonucleic acid).

– Contains instructions to make proteins– “Town Hall” or the “Boss” of the cell

3.2 Cell Organelles

Cell Nucleus Video 1m39s

3.2 Cell Organelles

There are two types of endoplasmic reticulum.

–* Rough endoplasmic reticulum

– Have bumps called ribosomes which link amino acids together to form proteins

–protein synthesis occurs here

– Ex: “Factory” of cell

3.2 Cell Organelles

–* Smooth endoplasmic reticulum

Makes lipids

3.2 Cell Organelles

* Golgi apparatus- processes, sorts, and delivers proteins to different parts of the cell

Ex: The “Post Office”

3.2 Cell Organelles

• Vesicles transport materials from place to place within the cell

Ex: Mailman/UPS

3.2 Cell Organelles

• * Mitochondria supply energy to the cell.

– convert the molecules you eat into usable energy– Where cellular respiration occurs

Ex: The “Power Plant”

3.2 Cell Organelles

Centrioles help divide DNA between splitting animal cells (mitosis and meiosis)

*only in animal cells

3.2 Cell Organelles

• Vacuoles are fluid-filled sacs that hold materials needed by the cell (water, food molecules, ions, and enzymes)

– Central vacuole only found in plant cells

Animal cell Plant cell

Ex: “Water Tanks/Grocery Store/Storage Facility”

3.2 Cell Organelles

• Lysosomes contain enzymes. – They They defend the cell from invading bacteria and defend the cell from invading bacteria and

virusesviruses– Break down damaged or worn out cell parts

*only in animal cells

– Ex: “Police” “Waste Treatment Center”

3.2 Cell Organelles

• A cell wall gives shape to the cell and provides protection– support the entire organism.support the entire organism.

*Only in plants

– Ex: Border of town-Wall around town

3.2 Cell Organelles

• * Chloroplasts convert solar energy to chemical energy. They carry out photosynthesis

*Only in plants

– “Solar Power Plant”
