1. Mind Stretcher - Friday 1.What are the two types of prokaryotic cells? 2.Which is larger: prokaryotic or eukaryotic cells? 3.Which type of cell has membrane bound organelles? 4.What type of cells make up the human body? Archea and Bacteria Eukaryotic

2. Standard S7L2b: Relate cells structures (cell membranes, nucleus, cytoplasm, chloroplasts, mitochondria) to basic cell functions

3. 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

4. The Parts Cells are made up of Different Parts! Each Part has a Specific Function! The Parts: –Nucleus –Mitochondria –Cytoplasm –Endoplasmic Reticulum –Ribosomes –Golgi Bodies (Apparatus) –Vacuoles –Lysosomes –Cell Membrane –Cell Wall –Chloroplast

5. Cell Membrane A protective barrier that encloses a cell. Separates the cells contents from the cells environment. Cell Membrane is like a Fence.

6. Cytoplasm Gel-like fluid found all throughout the cell. –Like Jell-O Constantly Moving (Swishing around) All Other Parts are Suspended in Cytoplasm!

7. The Nucleus DNA (our genes) Found here! Acts like the Brain! –Directs all of the cell’s activities i.e. tells all the other parts what to do! Houses Nucleolus

8. Nucleolus Found INSIDE the Nucleus!

9. Mitochondria Powerplant of the Cell Break down Sugar to Produce all Energy! –In the form of ATP

10. Where is Mitochondria??

11. Ribosomes Makes protein out of amino acid. All cells need protein to function. Ribosomes are like a Protein Factory!

12. Where are Ribosomes?

13. Endoplasmic Reticulum Carry Proteins and other cell materials from one part of cell to another! Two Types: Smooth and Rough –Rough E.R. has Ribosomes –Smooth E.R. does NOT have Ribosomes! Like Roadways!

14. Where is the: Rough E.R.?Rough E.R.? Smooth E.R?Smooth E.R?

15. Golgi Bodies : A.K.A Golgi Apparatus Recieves Proteins (mail) from the E.R. Packages them (puts it in envelope) Distributes them to other parts of cell (Mailman) Like Postoffice

16. Where are Golgi Bodies???

17. Vacuoles Stores food and water Large Vacuoles are found in Plant cells. Like a Storage Container

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

19. Lysosomes Break down old cell parts! Release them for recycling Like the Janitors of the Cell

20. Recap: Plant and Animal Cells are Made of Parts. Each Part has a Function: –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

21. Chloroplast Plant Cell Only!! Makes food for the cell. Chlorophyll traps the sunlight needed to perform photosynthesis and gives plants their green color. Like a Restaurant!

22. Cell Wall Plant Cell Only! Rigid, cellulose structure that gives support to a cell. Although made of different materials algae, fungi, bacteria, and archaea also have cell walls. Like a wall!
