1. Mind Stretcher – Copy Both
Which is larger: prokaryotic or eukaryotic cells?
What type of cells make up the human body? (Eukaryotic or Prokaryotic)
Eukaryotic

2. Directions Get out your organizer from Friday
Complete the back using pages 68 & 69 in the textbook

3. cytoplasm
Cell membrane

4. Discovering the Cell Standard S7L2b:
Relate cells structures (cell membranes, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions

5. Did You Know?
We are made up of microscopic living things called: CELLS
There are Approximately 100 TRILLION cells in the Human Body.
100 Trillion

6. The Parts Cells are made up of different parts called organelles.
Each part has a specific function!
The Organelles:
Nucleus
Mitochondria
Cytoplasm
Endoplasmic Reticulum
Ribosomes
Golgi Bodies (Apparatus)
Vacuoles
Lysosomes
Cell Membrane
Cell Wall
Chloroplast

7. Cell Membrane
Function- To protect the cell and allow things IN and OUT.
Analogy- A Cell Membrane is like a FENCE.
Found- Animal & Plant Cells

9. Cytoplasm
Function- Gel-like fluid found all throughout the cell; All other organelles are suspended (floating) in it.
Analogy- The Cytoplasm is like Jell-O, constantly moving & swishing around
Found- Plant & Animal Cells

11. Cyto + Plasm = Cell Shape
Cyto = Cells
Plasm= Shape
Cyto + Plasm = Cell Shape

12. Cytoplasm
Cytoplasm is basically the thick gel like substance that fills the cell sometimes called cytosol.
It helps move materials around the cell.
It contains enzymes, fatty acids, sugars, and amino acids that are used to keep the cell working.
It breaks down larger molecules so other organelles can use them.
Waste products are also dissolved before they are taken in by vacuoles or sent out of the cell.

13. The Nucleus
Function- DNA (our genes) is found here. It directs the cell’s activities and houses the nucleolus.
(Tells all the other parts what to do! )
Analogy- Acts like the Brain
Found- Animal & Plant Cells

14. Found INSIDE the Nucleus!
Nucleolus
Found INSIDE the Nucleus!

15. Mitochondria
Function- Performs respiration which breaks down sugar to produce energy! (In the form of ATP)
Analogy- “Power plant” of the Cell
Found- Animal & Plant Cells

16. Mitochondria
They are very small and cells may contain several thousand of them. It all depends on the cells needs.
If the cell feels it is not getting enough energy, than more can be created.
Food such as glucose (sugar) is broken down into carbon dioxide and water which releases energy.
We breathe in oxygen to help this process.

17. Where is Mitochondria??

18. What does it look like on the inside?

20. Ribosomes
Function- Makes protein out of amino acid. All cells need protein to function!
Analogy- Ribosomes are like a Protein Factory
Found- Animal & Plant Cells

21. Where are Ribosomes?

22. Endoplasmic Reticulum
Function- Carry proteins and other cell materials from one part of cell to another.
Two Types- Smooth ER and Rough ER
Rough E.R. has Ribosomes
Smooth E.R. does NOT have Ribosomes!
Analogy- Like Roadways/Highways
Found- Animal & Plant Cells

23. Where is the Endoplasmic Reticulum:
Rough E.R.?
Smooth E.R?

24. Golgi Bodies/Golgi Apparatus :
Function- Recieves Proteins (mail) from the E.R., Packages them (puts it in envelope) then Distributes them to other parts of cell (Mailman)
Analogy- Like Post office
Found- Plant & Animal Cells

25. Where are Golgi Bodies???

27. Vacuoles Function- Stores food and water;
Largest are found in plant cells and smallest in animal cells.
Analogy- Like a Storage Container
Found- Plant & Animal Cells

28. Some Animal Cells have Vacuoles while Others Don’t!!
Where is the Vacuole?
Some Animal Cells have Vacuoles while Others Don’t!!

29. Lysosomes
Function- Break down old cell parts & release them for recycling
Analogy- Like the Janitors of the Cell
Found- Plant & Animal Cells

31. Recap: Plant and Animal Cells are made of parts called ORGANELLES.
Each Organelle has a Function/Job:
Cytoplasm
Surrounds and Constantly Moves Organelles
Nucleus
Brain
Mitochondria
Powerplant
Endoplasmic Reticulum
Roadways
Ribosomes
Protein Factories
Golgi Bodies
Post Office
Vacuoles
Food Storage Containers
Lysosomes
Janitors

32. A plant cell has two more organelles that animal cells don’t!
But Wait…There’s More!
A plant cell has two more organelles that animal cells don’t!

33. Chloroplast Function- Makes food for the cell through Photosynthesis
Chlorophyll is a green pigment inside the chloroplast that traps the sunlight needed and gives plants their green color.
Analogy- Like a Restaurant/Chef
Found- Plant Cells

34. Cell Wall
Function- Rigid, cellulose structure that gives support to a cell.
Although made of different materials algae, fungi, bacteria, and archaea also have cell walls.
Analogy- Like a brick wall surrounding a building!
Found- Plant Cells
