29. Draw and label a worm showing the respiratory
system/gas exchange (5 points)

through which it absorbs oxygen and releases
carbon dioxide.

both nephrida/nephridapore) (5 points)

slime tube, seminal vesicles, ovary, clitellium,
cocoon. (25 points)
15
34. Show ( 5 pts) and describe with details (20
pts) the worms unique reproductive system(see
33 for drawing)

• The worm is hermophroditic, which means that it
  has both sex organs, the males testes (which
  produce the sperm) and the ovaries which are the
  females sex organ which produce the eggs.
• The worm can not self fertilize, it must take a
  mate and exchange sperm. This is called
  copulation.
• The worm copulates with its mate during the
  spring, when the ground is moist, and at night,
  for 2 hours.
• Once the sperm exchange (sliming) is complete, a
  cocoon is formed at the clitellium and moves over
  the worms head and falls off. It is left behind.
  It will produce a worm in about 2-3 weeks.

37. Who was Linneus and what did he do of
importance? (10 points)

• Father of classification... created the system
• Kingdom Phylum class order family genus species

19
38. What does being cold blooded do for the
earthworm? How does it benefit it? (25 points)

• The term is called Poikilothermic which means
  cold blooded. This means that the animals body
  temp becomes that of the environment. (10 pts)
• In the summer, when it is warm, the animal is
  very active and food is plentiful. In the winter,
  when the ground is frozen and hard, the body temp
  goes down, and the animal slows down and so does
  the need for a lot of food. This helps the animal
  live and survive even when the temp is cold. (15
  points)
