1. Prokaryotic vs. Eukaryotic Cells

2. Prokaryotic vs. Eukaryotic Cells
Animal and Plant cells are considered eukaryotic cells.
Eukaryotic: A type of cell that has membrane-bound organelles
Bacteria are considered prokaryotic cells.
Prokaryotic: A type of cell that has no membrane-bound organelles.

3. Do Now: Getting sick
Describe the last time in your life when you got sick. How did you feel? How long were you sick? How do you think you got sick? How did you eventually get better?

4. Contagion Why was everybody getting sick?

9. Prokaryotic Cells Usually smaller than eukaryotic cells
In organisms like bacteria and archaea
Only a part of unicellular (one cell) organisms
Reproduce asexually
Have NO MEMBRANE BOUND ORGANELLES
Contain ribosomes, a cell membrane, cell wall, cytoplasm and sometimes flagella
DNA is in a circular shape called a plasmid in the cytoplasm

10. Eukaryotic Cells Usually larger than prokaryotic cells
In animals, plants, fungi and protists
Can be part of unicellular or multicellular organisms
Reproduce sexually or asexually
Have MEMBRANE-BOUND ORGANELLES (mitochondria, nucleus, chloroplast, vacuoles)
DNA is packed into linear structures called chromosomes in the nucleus

11. All of these Organisms are made of Eukaryotic Cells

12. Prokaryotic vs. Eukaryotic DNA
Prokaryotic DNA: In a circular chromosome called a plasmid that floats in the cytoplasm.
Eukaryotic DNA: In linear chromosomes inside of the nucleus.
Note- Chromosome = a package of DNA

13. Do Now: 3-2-1
3 organelles that are in eukaryotic cells but not prokaryotic cells
2 differences in prokaryotic and eukaryotic genetic material
1 difference in size between prokaryotic and eukaryotic cells

14. Cells and Sickness Pathogenic Prokaryotic Cells cause... -strep throat
-food poisoning (salmonella, e. Coli)
-bronchitis
-cholera
-STI’s: chlamydia, syphilis, ghonarea
Pathogenic Eukaryotic cells cause...
Yeast infection
Malaria

15. Cells and Health Ways that eukaryotic cells help us
We are made of eukaryotic cells so they do everything for us!
Ways that prokaryotic cells help us
Help digest food
Help prevent stomach ulcers

16. Think about it …
Angel is looking at a cell under a microscope. She says that its eukaryotic. What is one way that she can know that its eukaryotic?
She sees that it has ribosomes
She sees that it has mitochondria
She sees that it has a cell membrane
She sees that it has cytoplasm
