1. Good Morning!
Unfortunately I cannot be with you guys today as I am at a professional development, but no worries I will be back tomorrow.  Mr. Hamm will be your sub and has instructions from me as well. This powerpoint will give you the run down of todays activities and hopefully answer any questions. All work is to be done individually.

2. Bell Ringer: 3/15/17
Objective: Identify organelles in prokaryotic and eukaryotic (plant and animal) cells.
Question: Using your Chromebook research the difference between Prokaryotes and Eukaryotes. Create a chart comparing the two.

3. Amoeba Sisters: Introduction to Cells
Worksheet that goes along with this is at station 7. When done place the finished worksheet into the turn it in bin.

4. Cell Organelle Chart Use the following slides to complete the chart.
State the function based on slide description.
Where is it found: Plant, Animal, or both?
Cell City Role: If you were to relate the cell to a city what role would this organelle have. Example: Mitochondria could be Duke Energy because they make energy.
Quick Sketch: Use the slides to make a quick drawing.

5. Cell Organelles!

6. Organelles
Specialized subunits of cells that have a particular function
Prokaryotes have a few (e.g., ribosomes)
Eukaryotes have many, usually surrounded by a membrane
This where we get the term “Membrane-bound organelles”

7. Cell Membrane Also called plasma membrane
Protects and supports the cell
Controls what enters and leaves the cell
It is a lipid bilayer (what does this mean??)
Found in all types of cells – prokaryotes and eukaryotes!

8. Cell Wall Found in eukaryotic plant cells
Main function is protection and support
Outside of cell membrane
Made of cellulose (a carb!)
Plant cells are surrounded by a rigid outer wall composed of cellulose.
The cell wall can also contain other components, mainly lignin.
Lignin: fills in the spaces between cellulose molecules which makes the cell wall even stronger
Major component of wood
Present in cells that make up the vascular system
Plant cells glued together by pectin

9. The Nucleus Controls most activities in the cell
Contains DNA – the coded instructions for making proteins and other molecules for the cell
The nuclear envelope has nuclear pores, where things can enter or leave
Largest organelle
Usually one per cell
Typically the easiest organelle to see
Contains the DNA
Surrounded by the nuclear envelope which is a double-layered membrane containing nuclear pores
Pores allow certain substances to pass from the cytoplasm to the nucleus and vice versa.
Pores are a selective filter
See?

10. Nucleolus Small, dense region in the middle of the nucleus
This is where ribosomes are formed.
The nucleolus is located inside the nucleus.
It is not an organelle, but rather a visible region within the nucleus.
It is the site of ribosome production

11. Cytoplasm Clear fluid within cell that contains all organelles
Moves materials throughout the cell
It’s the light blue/gray stuff in this picture

12. Ribosomes Makes proteins in the cell
May be free in cytoplasm or attached to ER
Proteins are vital to life – THE MOST IMPORTANT PRODUCT OF THE CELL!!
In prokaryotes and eukaryotes

13. Golgi Apparatus (Bodies)
Stacks of membranes used for storing, modifying, or packaging (the cell’s packaging plant!)
Packaged chemicals can be stored inside the cell or move outside the cell
Cells that make saliva or hormones have many Golgi bodies

14. Endoplasmic Reticulum
Series of folded membranes that form sacs or tubes
Two types – smooth and rough

15. Smooth ER vs. Rough ER Rough ER Smooth ER
Ribosomes make it look rough or bumpy
Ribosomes synthesize (make) proteins, so the Rough ER is where this happens!
Smooth ER
Smooth - no ribosomes!
Synthesizes (makes) lipids
Detoxifies drugs

16. Lysosomes Found in animal cells
Full of digestive enzymes to digest unwanted particles
Help white blood cells to destroy bacteria
Clean-up crew!

17. Vacuoles Store food, water, or waste materials
In plant cells, one large vacuole
In animal cells, a few small ones
Vacuoles and lysosomes working together! Amazing! Astounding!

18. Chloroplasts Found in eukaryotic plant cells
Capture light energy and convert it into chemical energy during photosynthesis

19. Mitochondria Energy producers – the “powerhouse” of the cell!
Convert chemical energy into useable energy thru cell respiration (Glucose ATP)
Found in animal and plant cells
Many mitochondria in muscle cells – why??

20. Cytoskeleton
Overlapping network of filaments and fibers that support the cell and help it maintain its shape
Can also help cells move
Microfilaments and microtubules

21. Centrioles are made of microtubules
They migrate to either side of the cell and help to pull it apart during cell division
Only found in animal cells!
Centrioles are made of microtubules

22. Flagellum
Extension of the cytoskeleton- Allows movement, main source of transportation for cells
Only some animals and some prokaryotes have these
Has rotary engine made of proteins that spins it, very similar to a car

23. Cilia/Pili
Extension of the cytoskeleton- Allows things to move around the cell. Propels mucus in your throat, helps with hearing in your ears, and helps move food particles in your stomach.
Only some animal cells and some prokaryotes
Has rotary engine made of proteins that spins it, very similar to a car

24. Plant and Animal Cell Label
Station #7 has a plant and animal cell. Use the words on the next slide to label the image. You may use your Biology book or google to assist you.
