10

Ribbon worms, though similar to flatworms,

have their own Phylum. What is it

called?

11

Nemertea

12

Members of Phylum Nematoda are

collectively known as what?

13

Roundworms

14

What kind of body plan do all Nematodes possess?

15

Pseudocoelom

16

What is Eutely?

17Eutely is when every

member of a particular species contains the exact

number of cells in their body (this is very rare)

18

Describe the Ascaris lifecycle

using 5 steps

191. Eat/drink something containing Ascaris eggs2. Larvae hatch in intestines, move to bloodstream,

and break into lung alveoli3. Cough up larvae & swallow back to intestines4. Mature to adults during 2nd trip to intestines5. Adults lay eggs that are passed in feces

20

What is the difference between Protostomes & Deuterostomes and which term applies to all

Pseudocoelomates?

21Protostomes – form the mouth before the anus

Deuterostomes – form the anus before the mouth

All Pseudocoelomates are Protostomes

22

Members of Phylum Annelida are collectively

known as what?

23

Segmented worms

24

What is the name for the thin, internal divisions between metameres in

Annelids?

25

Septa (Septum is singular)

26

Match the organism to the Annelid Class

28

What is the difference between parapodia and setae

29Parapodia are the fleshy, leg-like

protrusions on polychaetes that are used for locomotion. Setae are small hairs that most Annelids possess and

are used primarily for respiration and protection

30

Describe how earthworms reproduce

31 1. Worms line up and swap sperm2. Clitellum forms a cocoon around the

exterior of the worm3. The worm deposits its own eggs in the

cocoon4. The worm shimmies the cocoon towards the

head and deposits the partner’s sperm in the cocoon

5. The cocoon falls off and offspring mature inside
