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)
• Muscle at back of bladder contracts
8. Explain
to prevent urine from entering
why sperm
urethra as sperm leaves the body.
and urine
can never
mix.
Urinary bladder
Urethra
Penis
Vas deferens
Testes
Scrotum
Vas deferens
Seminal vesicles
Prostate
Cowper’s

Urethra
Penis
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
