2
What type of sponge is drawn
on the left side of the picture
3
Asconoid
4
What type of cell is denoted by the
label XXX?
5
Choanocyte
6
What type of cell is denoted
by the label XXX?
7
Sclerocyte
8
What type of cell is denoted
by the label XXX?
9
Archaeocyte
10
11
Pinacocyte
Atrium
Pore
Spicules
Archaeocytes
Choanocytes
12
Sponges are all aquatic
and mostly marine.
What does this statement
mean?
13
They all live underwater but
most live in salt water
14
Define sessile
15
Attached to the substrate
or immobile
16
Of what three substances are spicules
comprised?
17
Silicon, calcium carbonate, &
collagen
18
Match the Sponge Class with
the Description…
Hexactinnellida
Bath Sponges
Demospongiae
Asconoid Possible
Calcarea
Glass Sponges
19

20
Describe Sexual and
Asexual Reproduction
in Sponges
21
Sexual – Sponges release sperm into the
water when the temp. and moon are right
Asexual – Simply breaking apart
(fragmentation) or by sprouting miniature
clones called gemmules (budding)
22
What two body plans do all
Cnidarians go through
during their life cycle?
23
Polyp & Medusa
24
What are the 2 living
layers and 1 non-living
layer that make up
Cnidarian bodies?
25
Epidermis, Gastrodermis,
& Mesoglea
26
Describe the difference
between the way jellyfish
move versus the way a
man-of-war moves
27
Jellyfish pulse their velum underwater
in order to move
Man-of-war use their sail on the
pneumatophore to catch wind and
glide upon the surface of the water
28
Match the Cnidarian Class with the
Description
Anthozoa
Hydrozoa
Cubozoa
Scyphozoa
Box Jellyfish
Freshwater Possible
True Jellyfish
Coral & Anemones
29

30
Describe the relationship
between zooxanthellae and
coral
31
It is a mutualistic relationship. The
zooxanthellae provide the coral with
food while the coral provides the
zooxanthellae with a home.
32
What structure is denoted
by the number 7?
33
Mesoglea
34
What structure is denoted by
the number 10?
35
Gastrovascular cavity
36
What structure is denoted by
the number 1?
37
Cnidocyte
38
What structure is denoted by
the number 5?
39
Nematocysts
40
Someone come to the
board and draw the
generalized lifecycle of a
Cnidarian
41
42
Obelia contains
two types of
polyps. Explain.
37
The feeder polyps capture
and digest prey whereas the
reproductive polyps bud out
medusa
44
Name two similarities
and two differences
between Phylum
Cnidaria and Phylum
Ctenophora
45
Similar – radial symmetry,
diploblastic, & dead-end digestive
tract
Different – no cnidocytes or
polyp/medusa stages
46
Name two differences between
true jellyfish and box jellyfish
other than the potency of their
venom
47 True Jellyfish – round velum, no
eyes (rhopalia), & tentacles all
around the velum
Box Jellyfish – square velum, eyes
(rhopalia), and tentacles only
arising from the four corners of
the velum
48
Which class of sponge has spicules
that dissolve away when vinegar is
dropped on a slide?
49
Calcarea
50
Describe the relationship
between choanocytes and
archaeocytes
51
Choanocytes capture food from the
water and transfer that food to the
archaeocytes. Archaeocytes then
digest that food and pass the energy
to the other cells in the sponge.
52
What are the two hypotheses of
multicellularity
53
Pasteurization
