1. Topic: Reproduction Aim: Describe the processes of asexual reproduction and mitosis. Do Now: Take out your repro reading notes. With your 12 o’clock partner, discuss #’s 1 – 3 from your Repro ISN and the immune system questions on the next slide (YOU HAVE 4 MINUTES) HW: Meiosis Reading Notes due Friday. CL Skeletal and Muscular due tomorrow. Immune System due Friday

2. Immunity Review 1.Why is active immunity long term? 2.Identify the two ways you can get active immunity to a disease. 3.Identify the immune system disorder being described: a.It weakens the immune system so that the person can no longer fight pathogens b.The body attacks your own body cells c.Cells divide uncontrollably d.The body reacts to a harmless substance.

3. Where is DNA found in a cell? In the nucleus Chromosomes: –Made of genes  DNA gene

4. 1. How many cells are produced as a result of mitosis? 2 cells

5. 2. Identify the name of the new cells produced as a result of mitosis. Daughter cells daughter cells

6. 3. Compare the two new cells produced. Identical copies Same genetic code Same # of chromosomes 50

7. 4. If the original cell consists of 46 chromosomes, how many will be found in the daughter cells. 46

8. 5. Identify the 5 phases of mitosis. Interphase Prophase Metaphase Anaphase Telophase

9. 6. Identify the main event that occurs during interphase. Duplicating chromosomes chromatid centromere chromatid 1 chromatid 2 chromatids

13. 7. Identify 3 events that occur during prophase. Centrioles get to right position Spindle fibers form Nuclear membrane breaks down centrioles Spindle fibers

15. 8. Identify the main event that occurs during metaphase. Chromosomes line up along central axis. Spindle fibers attach to centromeres. Chromosomes Spindle fibers Centrioles

17. 10. Identify the main event that occurs during anaphase. Chromatids pulled to each end. What are the spindle fibers attached to???? Chromosome Spindle fibers

19. 11. Describe the 2 events that occur during telophase. Nuclear membrane reforms Cytokinesis – cell membrane “pinches in” to split cell into 2 pieces Cytokinesis

22. Plant cells: cell plate forms

24. Interphase Chromosomes replicating

25. Prophase Nuclear membrane breaks down, spindle fibers form, centrioles move to opposite poles

26. Metaphase Chromosomes line up in the middle

27. Anaphase Chromatids pull apart and move to opposite poles.

28. Telophase Nuclear membrane reforms and cytokinesis occurs.

29. Interphase Chromosomes replicating Daughter cells are genetically identical to each other and parent cell. (same # of chromosomes)

33. Mitosis – bone cells Parent cell Prophase Metaphase Telophase Anaphase

34. Rat – epithelial cells

35. REMEMBER! I Interphase P Prophase M Metaphase A Anaphase T Telophase http://www.youtube.com/watch?v=PQyAXiH5RrI IPMAT

36. Let’s Review! 1.Describe where chromosomes are found and what they are made up of. 2.Describe 2 characteristics of asexual reproduction. 3.Describe what occurs at each phase of mitosis.

37. Infectious diseases are caused by 1.deficiencies in the diet 2.allergies 3.microscopic organisms that can be transmitted from one organism to another 4.malfunctioning organs

38. A person with AIDS is likely to develop infectious diseases because the virus that causes AIDS 1.destroys cancerous cells 2.damages the immune system 3.increases the rate of antibody production 4.increases the rate of microbe destruction

39. In some individuals, the immune system attacks substances that are usually harmless, resulting in 1.an allergic reaction 2.a form of cancer 3.an insulin imbalance 4.a mutation

40. Uncontrolled cell division is known as 1.allergies 2.cancer 3.AIDS 4.infectious

41. The type of immunity in which antibodies and memory cells are produced is called 1.temporary immunity 2.active immunity 3.passive immunity 4.long-term immunity

45. 1 & 2: interphase 3,4,& 5: prophase 6:metaphase 7 & 8: anaphase 9 & 10: telophase (& cytokinesis)
