  1. Today’s AIM:How are the male and female reproductive systems designed? DO NOW: On Your Notes Classroom Expectations Reminders: Homework should be out for collection Enter and settle quickly and quietly It’s okay to be wrong on the Do Now, but it’s NOT okay to not try to do it The first 5 minutes are SILENT

  2. 1. Define the term “asexual reproduction”: and provide TWO specific examples of different types of asexual reproduction ____________________________________________________________________________________________________________________________________________________________

  3. 2. Ancient humans used genetic engineering for thousands of years to produce livestock, pets, and crops with combinations of useful characteristics that would otherwise not exist in nature. Identify AND briefly describe ONE form of genetic engineering which could have been used by ancient humans. ______________________________________________________________________________________________________________________________

  4. Reproductive Systems - Organ systems involved in the production and transfer of gametes • Gametes - "sex cells" that contain half of a person's genetic information (ex: sperm, eggs)

  5. Human Male Reproductive Anatomy C A D B Based on the diagram and table above, determine the order of structures which sperm cells pass through as they are released during sexual reproduction and briefly explain your reason for the sequence you have placed them in. 1. ______________________  2. ______________________  3. ______________________ _____________________________________________________________________________ _____________________________________________________________________________

  6. Human Sperm Cell (Male Gamete)

  7. 1. The “body” – or midsection – of a human sperm cell contains many more mitochondria than are normally found in regular body cells. Why do you think the concentration of mitochondria in sperm cells is so high? Base your answer on your knowledge of the structure and function of a sperm cell. • _________________________________________________________________________________________________________________________________________________________________________________________

  8. 2. Though it consists of different sections, each sperm cell is in fact just a single cell. What organelle is most likely found in the “head” of a sperm cell? How do you know? • _______________________________________________________________________________________________________________

  9. Some body structures of a human male are represented in the diagram below. An obstruction in the structures labeled X would directly interfere with the • (1) transfer of sperm to a female • (2) production of sperm • (3) production of urine • (4) transfer of urine to the external environment

  10. Human Female Reproductive Anatomy Fertilization: When a sperm + egg cell combine

  11. Human Female Reproductive Anatomy Fertilization: When a sperm + egg cell combine Implantation: A fertilized egg attaches to the wall of the uterus to receive materials for growth and development

  12. Quick Share Out • What would happen if an egg didn't implant properly in the uterus after fertilization?

  13. PRACTICE QUESTION: 1. _____Organ/structure in which a fertilized egg cell grows and develops into a fetus 2. _____ Performs a function analogous to the function performed by the testes in males 3. _____ The location where genetic information from father and mother combine 4. _____ The first place sperm cells are deposited during sex 5. _____ Performs a function analogous to the function performed by the vas deferens in males 6. _____ Responsible for producing cells containing half of the genetic information an individual needs 7. _____ Site where a fertilized egg implants into tissue and begins to develop

  14. Independent Practice • Complete Classwork 6.2 ON YOUR OWN • When you are finished, raise your hand for tonight's Homework • DUE TOMORROW: • HOMEWORK 6.2: Ectopic Pregnancy
