1. Topic: Cells Aim: What are the types of organisms & how are they organized? Do Now: Explain two differences between animal and plant cells. HW: pg 52-55 QandA 1-5 AND page 55 copy summary

2. 1.What are membrane-bound organelles? 2.Which cell organelles are known as recycling organelles? 3. What are chromosomes made up of? 4.When the Golgi bodies package a certain material, like a protein, what will the protein be surrounded by? 5.Where is the cytoskeleton found?

3. 2 types of cells 1.PROKARYOTIC CELL:

4. NO NUCLEUS DNA in cytoplasm No cell organelles Ex: bacteria

5. AnthraxStrep Cholera

6. 2.EUKARYOTIC CELLS:

7. HAVE A NUCLEUS Larger Contain organelles

9. Types of Living Things 1. Unicellular Organism:1-celled organism

10. AmebaEuglena

11. 2. Multicellular Organism:made up of many different cells that work together

12. Cells are SPECIALIZED (have specific jobs)

13. Ex: Muscle cells depend on nerve cells to move

15. How are cells in a multicellular organism organized?

16. 1. Cells Different cells have different jobs. Examples:

17. –Red blood cells carry oxygen.

18. –Muscle cells help you move.

19. 2. Tissue Group of similar cells that perform a specific function

20. Blood cells  blood tissue

21. Muscle cells  muscle tissue  movement

22. 3. Organ Many tissues working together Examples: heart, brain, stomach…

23. Heart =organ made of muscle, nerve & blood tissue

25. 4. Organ System Group of organs working together to perform a specific function

26. Skeletal & Muscular Systems

27. Circulatory System

29. 5. Organism A combination of organ systems that work together A living thing

30. Levels of organization Muscle cellSmooth muscle tissue StomachDigestive system CellsTissues Organs System Organism

32. Let’s summarize… 1.Explain the difference between prokaryotic and eukaryotic cells. Give examples of each. 2.Explain the difference between unicellular and multicellular organisms. 3.Explain the type of cells that make up a multicellular organism. 4.Explain the organization of an organism.

33. Review: 1. Which statement describing the cells in a body system is correct? (1)Each cell in the system is identical to the other cells in the system, and each cell works independently of the other cells. (2)Some cells in the system may be different from the other cells in the system, but all cells are coordinated and work together. (3)Each cell in the system is different from the other cells in the system, and each cell works independently of the other cells. (4)All cells in the system are identical to each other and work together.

34. 2. Which of the following is a primary difference between prokaryotic and eukaryotic cells? (1) Prokaryotic contain a membrane-bound nucleus. (2) Prokaryotic contain DNA. (3) Eukaryotic cells contain a membrane bound nucleus. (4) Eukaryotic contain DNA.

35. 3. Which sequence represents the correct order of levels of organization found in a complex organism? (1)Cells  organelles  organs  organ systems  tissues (2)Tissues  organs  organ systems  organelles  cells (3)organelles  cells  tissues  organs  organ systems (4)organs  organ systems  cells  tissues  organelles

36. 4. These groups of cells represent different (1) tissues in which similar cells function together (2) organs that help to carry out a specific life activity (3) systems that are responsible for a specific life activity (4) organelles that carry out different functions

37. 6. Which statement best compares a multicellular organism to a unicellular organism? (1)A multicellular organism has organ systems that interact to carry out life functions, while a single- celled organism carries out life functions without using organ systems. (2)A single-celled organism carries out fewer life functions than each cell of a multicellular organism. (3)A multicellular organism always obtains energy through a process that is different from that used by a single-celled organism. (4)The cell of a single-celled organism is always much larger than an individual cell of a multicellular organism.

38. Review: Put the following terms in order from least complex to most complex: Tissue Organism Cell System Organ Organelle

39. 1.What do prokaryotic cells contain? 2.What is a cell organelle found in a eukaryotic cell and not in a prokaryotic cell? 3.Explain the difference between a unicellular and multicellular organism.
