Marine
Science Final Exam Review
Algae
and Taxonomy
1
The correct order from largest to
smallest groupings in taxonomy is Kingdom, Phylum, Class, Order, Family Genus,
Species
2
. The science of classifying organisms is called ) taxonomy
3.
A species is a population of organisms that share common characteristics, can
breed with each other and are reproductively isolated from other populations
4.
In addition to chlorophyll, most blue-green algae contain a bluish pigment
called phycocyanin
5.
Cyanophyta have species that are capable of fixing nitrogen to make proteins.
6. Diatoms are enclosed by frustule made of
silica (SiO2)
7
.Cord grass plants are land plants tolerant to salt
8. Seagrasses: release pollen, the male gamete,
to be carried by water currents
9. Dinoflagellates:reproduce
by simple cell division, may produce blooms known as red tides and may
bioluminesce
10 Mangroves are land plants that can tolerate
salt, have thick leaves to reduce water loss and have seeds that germinate
while still attached to the parent tree
Protozoa and Sponges-Inverts A
1The
Mesozoa and Parazoa may be said to belong to a cellular level of organization.
2
The members of the Class Hexactinellida are also called Glass sponges
3
the Leuconoid form yields the greatest amount
of surface area to volume ratio in a sponge?
4
Sponges have a tremendous ability to repair injuries and to restore lost parts
in a process called. Regeneration
5
A certain unicellular eukaryote has a siliceous (glasslike) shell and
autotrophic nutrition. It is most likely a
radiolarian.
6
Unlike most other animals, sponges lack
a digestive tract symmetrical body plan nerve cells
7
Cells of the outer surface of the sponge obtain nutrients by absorbing food distributed by amoeboid like
cells
8
The Phylum Porifera does NOT have True tissues and organs
Inverts
B
1. The subphylum Urochordata includes Tunicates
2. "Echinoderm" literally means spiny skin
3. The larva stage of the barnacle that is
responsible for site selection for attachment is cypris larva
4 Some of the most common and widespread marine
animals are copepods.
5. The most distinctive feature of the ribbon
worm is a proboscis
6 The presence of nematocysts and symmetry are
fundamental characteristics of Cnidarians
7. Comb jellys are different
from jellyfish in that they do not have stinging cells
8. The statocyst is sensitive to
gravity/equilibrium
9.
Gills of clams collect food as well as O2
10. the
abdomen located in the crab is under the cephalothorax
11. The class Crustacea of Arthropods is the dominant class in the
marine environment.
12. Madraporite,
Stone canal.
13 The
presence of a notochord first becomes evident in phylum Chordata.
14. Bivalvia can produce pearls?
15. Bivalvia have two shells?
16. .Polyplacophora have 8 shells?
17. Scaphopoda have thread-like tentacles and
live burrowed in the sand
Fish
1.
Bony, but not cartilaginous, fishes often have swim bladders, and have a bony
operculum over the gills and bony fin rays to support the fins.
2.
The lateral line is sensitive to low
frequency vibrations .
3. Egg laying in sharks include oviparous
ovoviviparity viviparous
4. Fish smell food using chemoreceptors
5. The caudal fin is responsible for
locomotion in most fish.
6 If
the fish has biting, chewing type of teeth, it is probably a predator
7. Structures in fish used to taste food in
muddy waters are called barbals
8. The gill is found behind the mouth
9. Shamu's coloring is an example of
countershading
10. verticercal
is NOT a type of tail fin found in
fish?
11. Cells that remove salt from the body of the
fish are called chloride cells
Turtles
Birds
1. A clutch is a group of eggs
that sea turtles lay at one time
2. In loggerhead turtles,
the incubation temperature helps determine the sex of the hatchlings. If the
temperature is about 28 degrees C, the hatchlings sex going to be male
3. The T.E.D. device is
put on the nets of shrimpers to help the seaturtle escape from drowning
4. The frigate bird steals food from other birds.
5. All land vertebrates have descended
from: bony fishes
6. Seabirds
are endotherms
7. The only time marine
turtles leave the sea is to lay eggs
8. Bradycardia refers to decreased heartbeat
during diving
9.Smell/chemicals is
thought to help marine turtles navigate to their natal beaches
10. The only marine lizards are found in the
11. The biggest sea turtle
is the Leatherback
12. The bird has a large pouch on its beak and
forces water out after catching a fish is the pelican.
13. The function of salt
glands is toremove excess salt from the body
14 Penguins are found mostly in the Antarctic region.
15 Seabird guano can be
used for useful human purposes.
Marine Mammals
1. The largest group of
pinnipeds is theSeals
2 Immediately after their
birth, the young of cetaceans swim to the surface of the water
3.The
tail of cetaceans ends in a pair offlukes
4 cetaceans, sirenians,
and pinnipeds. use blubber for insulation:
5.Manatees
and dugongs are related to elephants
6.Cetacians spends
all of their lives in the water.
7. Baleen whales are an example of Planktivorous
nekton
8 a cetacean is adapted to determine sound
direction underwater by receiving sound
through the jaw
9
Breathing is similar in cetaceans and pinnipeds because both require a
conscience effort
10. Seals,
sea lions, and walruses, which have blubber, flippers, and breed on land,
belong to the order Pinnipedia
11 Delayed implantation of the embryo allows
pinnipeds to time the birth of pups with the arrival of the pregnant female in
breeding areas
12 Small, toothed whales are often referred to
as dolphins or porpoises
