1. Cell types, structures and functions

2. Good morning!
Get your journals out
On the next page of your journal title it Prokaryotes and Eukaryotes
On the next line write:
EQ: How are prokaryotes and eukaryotes a like and different?
Make sure that you put prokaryote and eukaryote in your table of contents!

3. Cells exploration guide
With your group look at the 3 pictures of cells
Use the pictures to fill in the chart
Write YES if it is there
Write NO if it is not there
Highlight all of the boxes that say YES – this will help later
Answer the questions on the back
Tape/glue this on the left side of the page

4. Abiotic vs Biotic Bio = life Biotic = living organisms Examples:
Abiotic = not living

5. What are the Characteristics of Life?

6. Biotic or Abiotic?

7. Biotic or Abiotic?

8. Biotic or Abiotic?

9. Biotic or Abiotic?

10. How do we define life? Cell Theory
All living organisms are composed of cells
Cells are the smallest structures that perform the functions of life
All cells come from preexisting cells

11. What do all cells have in common?
All cells have common structures
Cell membrane
Ribosomes
Cytoplasm
Cells contain DNA
Cells are the basic unit of life

12. Make a three column chart

13. Two Cell Types Prokaryotic Pro = before Eukaryotic Kary = nucleus
Eu = true
A cell type before the evolution of a nucleus
Cell with a true nucleus
Example = bacteria
Example = animal

14. Cell History Prokaryotic Eukaryotic Ancient cells Modern cells
Evolved 3.5 bya
Modern cells
Evolved 1.4 bya
Stromatolites, ancient bacterial formations

15. Cell Size Prokaryotic Eukaryotic Smaller cells Larger cells 1 to 10 µm

16. Cell Size Comparison

17. Cell Organization Prokaryotic Eukaryotic
Simple cells with all parts in “one room”
Complex cells with many compartments

18. Location of DNA Prokaryotic Eukaryotic
DNA is loose in the cytoplasm (no nucleus)
DNA is protected in the nucleus

19. Presence of Organelles
Prokaryotic
Eukaryotic
Ribosomes only
Many, membrane – bound organelles

20. Type of Organisms Prokaryotic Eukaryotic Bacteria only! Plants Animals
Fungi
Protists

21. Size of Organisms Prokaryotic Eukaryotic
Always unicellular (single cell)
Mostly multicellular (more than one cell)
Bacteria are cell size
Range from cell size to the size of a giant tree

22. What are Viruses? Viruses are not considered living because:
They are not made up of cells
They need a host to reproduce
Viruses are much smaller than cells
Viruses and cells both contain DNA

23. Gallery Walk
In your notebook write down if the cell is prokaryotic or eukaryotic A B C D

24. Prokaryote or Eukaryote?
It’s time to play is it a Prokaryote, Eukaryote or both!

25. Card sort
Work in partners and match which cards are prokaryotes and which ones are eukaryotes

26. Venn Diagram
Use or cell exploration guide and your notes and make a Venn Diagram in your journal
Use one whole page
Animal Cell
Plant Cell

27. What are organelles?
An organelle is a “mini organ” inside a eukaryotic cell that carries out a specific function

28. Make a T chart One side says organelle One side says Function

29. Cell Membrane Lipid bilayer that surrounds the cell
Embedded proteins control what materials enter and leave the cell

30. Cytoplasm Jelly – like fluid inside the cell membrane
Supports and holds all the organelles

31. Ribosomes
Where proteins are assembled
Translate genes into proteins

32. Cell Wall Support, strength, and protection
Found outside plasma membrane
In prokaryotes and plant cells
Made out of cellulose
Bacteria Cell Wall
Plant Cell Wall 

33. Flagella/Cilia
Extensions of the plasma membrane that allow for movement

34. Nucleus Membrane bound area where chromosomes are found
Holds the DNA, or genetic information

35. Nucleolus
Dense region found in the nucleus where ribosomal RNA is made

36. Mitochondria
Produce ATP (energy) for the cell during cellular respiration
C6H12O6 + 6O H2O + 6CO2 + ATP
Composed of inner and outer membrane
Powerhouse of the cell

37. Chloroplasts Contains chlorophyll Site of photosynthesis reactions
6H2O + 6CO C6H12O6 + 6O2
Plant cells only
sunlight

38. Endoplasmic Reticulum
Membranous stacks with rough and smooth sections
Participates in making (synthesizing) proteins and membranes

39. Golgi Apparatus
Modifies and packages proteins for secretion by budding of vesicles

40. Lysosomes Contains enzymes that break down cell wastes and foods
Recycle old cell parts
Lysosomes contain digestive enzymes 

41. Vacuole
Stores water and pigments in plant cells

42. Centrioles
Used to organize chromosomes during cell division using spindle fibers
