5.  Take out one sheet of paper, you will share with a partner. You will use ½ sheet of paper.  Write the correct heading and title.  Write the questions down.  Write the correct answer below each question.  You will be working with your shoulder partner, but you need to turn in your own responses.

6. 1. What is respiration? (Use all the information on the graphic organizer) 2. What is photosynthesis? (Use all the information on the graphic organizer) 3. How are both processes connected? 4. Which process do animal cells do? Which process do plant cells do? 5. Why is mitochondria important for cells? 6. Why are chloroplasts important for cells?

7.  What is DNA?  DNA stands for deoxyribo nucleic acid  is present in the nucleus  Gives the cell all of the information it needs (controls the kind of cell a cell will be, what it will do, when it will do it, and how it will do it)  DNA controls what kind of organism you will be (human, flower, monkey, chicken, bacteria) 2 7R

8.  What is DNA made up of?  A chain of nucleotides made of three groups: sugar, phosphate, and organic base  A double helix is made when nucleotides pair with other nucleotides and twist to look like a twisted ladder PO 4

9. 12

10. sugar-phosphate chain bases 14

11.  What are chromosomes  Chromosomes are DNA strands and are compacted and coiled.

12. 15

13. 1. Why is DNA important? 2. Where is DNA found? 3. What is the shape of DNA (what it looks like)?

14.  1. Do Now  2. Check HW Flashcards  3. Notes- DNA and Differentiation  4 Read together pages 138-141  5. Lets differentiate  HW. Summaries for pages 7 and 8 in your notebook

15.  1. In which organelle is DNA found at?  2. Which cells have DNA?

17.  All animal cells do not look alike!  Different cells have different shape, structure, and organelles, therefore they function differently!  Brain cells do not do the same thing as muscle cells.

18.  What is differentiation?  Differentiation: when a cell changes its structure making it a specialized cell capable of having specific functions.

19. Why do we need different kinds of cells? What determines what a cell will look like?  Every part of our bodies do different things therefore the cells at each different part needs to be different  DNA determines what the cell will be

20. How does differentiation happen? An undifferentiated cell or stem cell turns into whatever the body needs for it to be. Stem cell  differentiated cell Since the cell has all the DNA, the DNA that is not used is turned off and the information for identify of cell is left on

21. 1. Explain differentiation in your own words. 2. T/F A muscle cell can differentiate into a brain cell

22. 1. Do Now 2. Check Homework 3. Reading Together: 138-141 4. Lets differentiate Activity 5. Break 6. Intro to Mitosis-Notes 7. Brain-pop-Cancer Homework Cell Project due Friday 8/6/13

23. 1.2. 3.4. 8R

24. 1. Divide ball into two equal parts and reshape to ball shape. Record in your notebook. 2 Divide each ball into two smaller ones. By now you should have four total. Record in your notebook.

25. 3. Differentiate: Shape each “Blank Cell (undifferentiated cell) into four different shapes (now differentiated cells). Record in your notebook. 4. Divide each “Differentiated Cell” into two identical ones. Record in your notebook.

26. 1.When an organism is first formed, is this organism undifferentiated or differentiated? 2. What determines what structure or function a cell will take when it differentiates? 3. In your own words describe what differentiation is. 4. Why is differentiation important?

27.  What needs to occur to cells in a growing organism?  Cells need to multiply  Cells do not grow as we grow instead our cells multiply! 9R

28.  Why would you need to make new cells?  If you are growing  To replace dead cells  If needed during developmental stage (puberty)

29.  How do cells multiply?  Cells go through a series of steps called the cell cycle (Mitosis)  The cell cycle has 3 stages: Interphase, mitosis, cytokinesis

30.  What are the three stages of the cell cycle?  1. Interphase: Copies DNA  2. Mitosis: DNA is distributed into the two cells  3. Cytokinesis: cytoplasm divides  The time a cell cycle takes depends on cell type, but is usually 24 hours

32. Stage that occurs before mitosis Cell grows to original size DNAs is copied (# doubles) this is called replication CELL MEMBRANE Nucleus Cytoplasm

34. First stage of Mitosis Copies of DNA pair up into chromosomes Centrioles (or poles) appear move to opposite end of the cell. Spindle fibers form between the poles. Centrioles Sister chromatids Spindle fibers

35. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm Spindle fibers Centrioles

36. Second stage of mitosis Chromatids (or pairs of chromosomes) attach to the spindle fibers. Chromosomes line up at the center Centrioles Spindle fibers

38. Third stage of mitosis Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell. Centrioles Spindle fibers

39. Animal Cell Plant Cell Photographs from: http://www.bioweb.uncc.edu/biol1110/Stages.htm

40. Fourth stage of mitosis Two new nuclei appear. Mitosis ends. Nuclei Chromatin

42. Occurs after mitosis Cell membrane pinches to create two daughter cells – each with its own nucleus with identical chromosomes. Plant cells make cell plate between two cells
