  1. Topic: Reproduction Aim: Describe the structure of the male reproductive system. Do Now: HW: Read pgs. 630 and 631. Write a paragraph (at least 4 sentences) describing each stage of the menstrual cycle. • Which type of cell division does this diagram represent? Explain your answer. • If organism A contains 88 chromosomes, how many chromosomes would the offspring contain?

  2. 46 23 23 23 23

  3. A B C F D E • Identify the process represented in the diagram. • 2. How is this different from animal cell mitosis? • 3. If the first cell is made up of 32 chromosomes, how many chromosomes are found in the daughter cells?

  4. Spermatogenesis

  5. Testes: produce sperm and testosterone • Scrotum: protects the testes and keeps testes cooler for sperm production • Vas deferens: tubes that carry sperm from testes to urethra

  6. Glands – produce fluids that make up SEMEN (used to transport sperm)

  7. Urethra: tube that carries SPERM and URINE out of the body • Penis: male organ that transfers sperm into female

  8. Let’s summarize… • Describe the process that occurs in the testes. • Describe the pathway of sperm out of the body. • Explain the importance of semen.

  9. In human males, sperm cells are suspended in a fluid medium. The main advantage gained from this adaptation is that the fluid  (1.) activates the egg nucleus so that it begins to divide  (2.) provides currents that propel the egg down the oviduct  (3.) removes polar bodies from the surface of the sperm  (4.) acts as a transport medium for sperm

  10. The scrotum is an important adaptation in human males because the optimum temperature for sperm development is  (1.) 10 to 12 degrees below normal body temperature  (2.) 10 to 12 degrees above normal body temperature  (3.) 2 to 4 degrees above normal body temperature  (4.) 2 to 4 degrees below normal body temperature

  11. In the human male, sperm leave the body through the (1.) urethra (2.) testes (3.) epididymis (4.) vas deferens

  12. In the human male, gametes are produced in the (1.) prostate gland (2.) testes (3.) bladder (4.) urethra

  13. Sperm is transported to the urethra by tubes called (1.) prostate gland (2.) testes (3.) bladder (4.) vas deferens

  14. D Urinary bladder vas deferens C B Glands Glands E Glands F A testes G penis H urethra

  15. A B What is the difference between process A and process B?
