6. Take your best guessAt your tables… • You have a pile of animal eukaryotic cells, plant eukaryotic cells, and prokaryotic cells. • With out gluing them, put them where you think they belong in the following table • After I check you off, write down your observations related to each cell type. • What do they look like? What’s inside and what do they look like? How are they similar? Do they have similar parts? How are they different? Do they have different parts?

7. 1.3 Eukaryotic Vs. Prokaryotic • On the back • You have a pile of animal eukaryotic cells, plant eukaryotic cells, and prokaryotic cells. • With out gluing them, put them where you think they belong in the following table • After I check you off, write down your observations related to each cell type. • What do they look like? What’s inside and what do they look like? How are they similar? Do they have similar parts? How are they different? Do they have different parts? • Eukaryotic cells • Anmial Cell • Observations • Plant Cell • Observations • Prokaryotic cells • Observations

8. Animal Cell

9. Plant Cell

10. Prokaryotic Cell

11. What’s similar between prokaryotes and eukaryotes • Both Prokaryotes and Eukaryotes are surrounded by membranes • Both Prokaryotes and Eukaryotes have DNA • Both Prokaryotes and Eukaryotes DNA make proteins that carry out the functions of the cell

12. 1.3 Eukaryotic Vs. Prokaryotic What’s similar between prokaryotes and eukaryotes • Both Prokaryotes and Eukaryotes are surrounded by membranes • Both Prokaryotes and Eukaryotes have DNA • Both Prokaryotes and Eukaryotes DNA make proteins that carry out the functions of the cell

14. What’s the difference between Eukaryotic and Prokaryotic Cells • Eukaryotic Cells are multi-cellular organisms that have membrane bound organelles: nucleus, endoplasmic reticulum, golgi apparatus, vacuoles, vesicles, mitochondria and chloroplast (plants) • DNA is stored in the membrane bound nucleus • Prokaryotic cells are single celled bacteria with no membrane bound organelles or nucleus. • DNA is free floating in the cell MORE TO COME ON ORGANELLES NEXT TIME!!!!!

15. 1.3 Eukaryotic Vs. Prokaryotic What’s similar between prokaryotes and eukaryotes What’s the difference between Eukaryotic and Prokaryotic • Both Prokaryotes and Eukaryotes are surrounded by membranes • Both Prokaryotes and Eukaryotes have DNA • Both Prokaryotes and Eukaryotes DNA make proteins that carry out the functions of the cell • Eukaryotic Cells are multi-cellular organisms that have membrane bound organelles: • DNA is stored in the membrane bound nucleus • Prokaryotic cells are single celled bacteria with no membrane bound organelles or nucleus. • DNA is free floating in the cell

16. Prokaryotic cell versus Eukaryotic cell

17. HW • Write a 6 sentence paragraph telling me how Eukaryotic and prokaryotic cells are similar and how they are different.

18. Math Minute

19. Compounds in Bacteria and Mammals • All cells contain carbohydrates, lipids, proteins, and nucleic acids, as well as water and other inorganic compounds. But do all cells contain the same percentages of these compounds? The graph compares the percentage of some compounds found in a bacterial cell and a cell from a mammal.

20. Red bars represent percentages of compounds in bacterial cells; blue bars represent percentages of compounds in mammalian cells. Reading Graphs: What do the red bars represent? What do the blue bars represent? Compounds in Bacteria and Mammals

21. About 70%; the percentages are the same. Interpreting Data: What percentage of a mammalian cell is made up of water? How does this compare to the percentage of water in a bacterial cell? Compounds in Bacteria and Mammals

22. Proteins Interpreting Data: Which kind of compound–proteins or nucleic acids–makes up the larger percentage of a mammalian cell? Compounds in Bacteria and Mammals

23. Drawing Conclusions: In general, how do a bacterial cell and mammalian cell compare in their chemical composition? Compounds in Bacteria and Mammals • They are similar, though mammalian cells have a lower percentage of nucleic acids, and bacterial cells have a lower percentage of lipids and fewer proteins.
