  1. Topic: Reproduction Aim: EXAM Do Now: Take our yesterday’s reading notes and then CLEAR YOUR DESKS. HW: Castle Learning due Tuesday!

  2. Topic: Reproduction Aim: Describe the stages of embryonic development. Do Now: Take our yesterday’s reading notes. HW: Take Home Test due Monday!!!!

  3. A cranium rib cage vertebrae B D C 1. Identify the labeled structures in the diagram. 2. Identify the bones that protect the spinal cord. vertebrae 3. Identify the bones that protect the brain. cranium 4. Identify the bones that protect the heart and lungs. rib cage 5. Where is cartilage found? In rib cage, tip of nose, ears, between bones (joints), between vertebrae humerus E pelvis F femur

  4. Part of the body’s first line of defense against disease-causing organisms is • the immune system b. the skin c. antibodies d. interferon

  5. Which substances may form in the human body due to invaders entering the blood? a. nutrients  b. vaccines  c. antibodies d. red blood cells

  6. Molecules that are foreign to your body are called • antibodies b. white blood cells c. antigens d. histamines

  7. Which statement regarding antibodies is correct? • Antibodies engulf the pathogen. b. Antibodies are found on the surface of pathogens. c. Antibodies attach to antigens that are on the surface of pathogens. d. Receiving antibodies provides active immunity.

  8. Once you have had the chicken pox, it is unlikely that you will ever get the disease again because your body has developed a(n) • passive immunity.   b. addiction.   • active immunity.   • antibiotic.

  9. Immunity that occurs when a body receives antibodies is called _________immunity. • Passive b. Temporary c. Shortened d. Active

  10. An injection of a weakened virus that allows one to develop immunity against a disease is called a • antibody b. vaccine c. epidemic d. pathogen

  11. 1. Identify the process that results in a zygote. • Fertilization

  12. 2. Identify or DRAW the process of fertilization. ZYGOTE FERTILIZATION

  13. fertilization zygote

  14. 3. Identify the name of the process in which the zygote undergoes mitosis. • Cleavage

  15. 4. Identify or DRAW the cleavage.

  16. cleavage fertilization zygote

  17. No cell growth

  18. zygote 2 3 1 5 4 • Identify the zygote. • Identify the stages that represent cleavage.

  19. 5. Identify the structure that forms as a result of cleavage. • Morula

  20. 6. Describe the structure of a morula. • A solid ball of cells

  21. 7. Identify or DRAW a morula.

  22. morula cleavage fertilization zygote

  23. 8. Identify the structure that forms AFTER the morula. • Blastula

  24. 9. Describe the structure of a blastula. • Hollow ball of cells

  25. 10. Identify or DRAW a blastula.

  26. morula blastula cleavage fertilization zygote

  27. This takes about 6–7 days http://www.youtube.com/watch?v=6lnr4HWiz9M

  28. zygote cleavage 2 3 1 5 4 • Identify the morula. • Identify the blastula,

  29. 11. Identify the structure blastula attaches to in the female. • Endometrium (lining of the uterus)

  30. 12. Identify the structure that forms after the blastula. • Gastrula

  31. 13. Identify the three layers that make up the gastrula. • Endoderm • Mesoderm • Ectoderm

  32. 14. Identify or DRAW a gastrula.

  33. Look at the prefix of each word to help you identify each layer. • Endoderm • Mesoderm • Ectoderm A B C

  34. gastrula morula blastula cleavage fertilization zygote

  36. Do any of the cells that make up these structures have a function? What are these cells called?

  37. 15. Identify and describe differentiation. • Differentiation occurs when the three germ layers start to DEVELOPinto DIFFERENTcells and eventually different STRUCTURES.

  39. Mitosis Fertilization Let’s summarize… • What type of cell division occurs throughout the formation of an embryo? • Identify the process that produces the zygote. • Identify the process that occurs to the zygote. • Identify the solid ball of cells. • Identify the hollow ball of cells. • Which structure attaches to the endometrium? • Identify the structure that forms when one side of the blastula indents. • Identify the process that occurs once the gastrula forms. Cleavage Morula Blastula Blastula Gastrula Differentiation

  40. Cells such as nerve cells and muscle cells are known as • gametes • sex cells • somatic cells • specialized cells
