1.Identify the process in the diagram. Support your answer. 2.Explain what occurs to the number of chromosomes in the process. 3.What type of reproduction uses this cell division. 4.What type of cell reproduces using this type of cell division.

1. Describe the function of the testes. Produce testosterone and sperm

Spermatogenesis

1.Where is DNA found in a sperm cell? 2.Why do sperm cells have a large # of mitochondria?

2. Identify the structure that keeps the testes outside the body. Scrotum

3. Why are the testes located outside the body? Sperm kept at a lower temperature than the rest of the body Lower temp  greater # of sperm

4. Identify the structures that sperm away from the testes. Sperm ducts Vas deferens

5. Describe the makeup of semen. Mixture of sperm and fluid Supplies sperm with an energy source and helps them move Did you know… Sperm are dead by the time the semen has dried. Inside a woman's body, sperm can live for up to five days depending on the conditions. Just one sperm to fertilize an egg and achieve a pregnancy. The typical ejaculate is about 2 – 6 mL (1/2 teaspoon to 1 teaspoon). Approximately twenty million or more sperm per mL is considered normal. Men produce sperm throughout their lives. Even elderly men can conceive a child.

6. Identify the structures that release fluids that make up semen. Seminal vesicles Prostate gland Cowper’s (bulbourethral) gland

7. Identify the structure that releases semen from the body. Urethra Penis (implants sperm into the female)

8. Explain why sperm and urine can never mix. Muscle at back of bladder contracts to prevent urine from entering urethra as sperm leaves the body.

Testes Scrotum Vas deferens Urethra Penis Urinary bladder

Testes Vas deferens UrethraPenis Seminal vesicles Prostate Cowper’s gland

Let’s summarize… 1.Describe the process that occurs in the testes. 2.Describe the pathway of sperm out of the body. 3.Explain the importance of semen.

The type of asexual reproduction in which involves the production of single cells by mitosis that are released into the environment is called 1.regeneration 2.binary fission 3.sporulation 4.vegetative propagation

The type of asexual reproduction in which one cell divides into to two cells that are of equal size is called 1.regeneration 2.binary fission 3.sporulation 4.vegetative propagation

Asexual reproduction in plants is known as 1.regeneration 2.vegetative propagation 3.binary fission 4.sporulation

Asexual reproduction that involves the regrowth of a lost body part is known as 1.regeneration 2.vegetative propagation 3.binary fission 4.sporulation

Asexual reproduction in which there is an unequal division of cytoplasm is called 1.regeneration 2.budding 3.binary fission 4.sporulation

Asexual reproduction in plants that occurs as a result human activity is called 1.regeneration 2.artificial vegetative propagation 3.binary fission 4.sporulation

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

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

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

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

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