2. Review What are the 6 characteristics of living organisms?
What are the 3 parts to cell theory?

3. Prokaryotes and Eukaryotes

4. Cells are broken into two categories :
Prokaryote “style”
Eukaryote “style”

5. Prokaryote cells are smaller and simpler
Do not contain a nucleaus
Commonly known as bacteria
microns in size

6. These are prokaryote
E. coli bacteria on the head of a steel pin.

7. Prokaryote cells are simply built (example: E. coli)
capsule: slimy outer coating
cell wall: tougher middle layer
cell membrane: delicate inner skin

8. Prokaryote cells are simply built (example: E. coli)
cytoplasm: inner liquid filling
DNA in one big loop
pilli: for sticking to things
flagella: for swimming
ribosomes: for building proteins

9. Prokaryote lifestyle unicellular: all alone colony: forms a film
filamentous: forms a chain of cells

10. Prokaryote Feeding Photosynthetic: energy from sunlight
Disease-causing: feed on living things
Decomposers: feed on dead things

13. Eukaryotes

14. Eukaryotic Have a nucleus (DNA contained in nucleus)
More complex that prokaryotes
Plant
Animal

15. Eukaryotes
Many types of eukaryotes live on their own. These cells live on their own and are capable of providing/finding all that they need to live.

16. Eukaryotes
However, many eukaryotic cells cannot live on their own. These are usually found living in community in an organism. Often they have are “specialized”, designed to do a specific job in an organism.

17. Prokaryotes and Eukaryotes

19. Flubber
On a piece of paper determine if flubber is living or non-living based on what you observe in the video.

21. Levels of Organization

22. Cell Organization
Cells are organized into systems that, together, perform functions that keep the organs healthy and alive.

23. Cells
A cell is the basic building block on which the body is built on. The body is simply a collection of cells that do different jobs that live together in community.

24. Tissues Tissues: groups of similar cells that do the same sort of work
Ex: Skin cells make up skin tissue

25. Organs and Organ Systems
Organs: different types of tissues working together
Organ systems: a group of organs working together to do a certain job.

27. Bone Cells are surrounded by a hard substance made of calcium and phosphorus

29. Nerve cells are long and have many branches
Nerve cells are long and have many branches. This allows them to receive and deliver messages quickly.

31. Muscle cells are usually long and have many fibers that can contract and relax.

33. Skin cells are mostly flat and close together
Skin cells are mostly flat and close together. They form a protective layer for your body.

35. What does it take to make a city?
What systems are needed for a city to function and grow?

37. Pre-AP What is the most “ancient” organisms on the earth?
Why do they have a special domain for themselves?
Describe the physical characteristics of a prokaryote.
Why cant multicellular organisms’ cells survive on their own?
How do cells, tissues, organs, organ systems, and organisms relate to one another?
Prokaryotes are capable of linking together. Does this make them a multicellular organism? Why or why not?

38. 6th Grade Science What is the most “ancient” organisms on the earth?
Why do they have a special domain for themselves?
Describe the physical characteristics of a prokaryote.
Describe a paramecium.
What are tissues?
How do cells, tissues, organs, organ systems, and organisms relate to one another?
