Final Jeopardy
Members of Phylum Platyhelminthes are
collectively known as what?
2
Flatworms
3
4
All flukes must pass through what kind of intermediate host during their
lifecycles?
5
Snails
6
What are the three living (dermal) layers of tissue that
comprise the bodies of triploblastic animals?
7
Endoderm, Mesoderm, & Ectoderm
8Match the worm to the correct
Class…
Trematoda PlanariansTurbellaria TapewormsCestoidea Flukes
9
Trematoda PlanariansTurbellaria TapewormsCestoidea Flukes
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
Oligochaeta Tube/Lug/FirewormsPolychaeta LeechesHirudinea Earthworms
27
Oligochaeta Tube/Lug/FirewormsPolychaeta LeechesHirudinea Earthworms
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
