Q

2 ways of reproduction for a sponge

A

spawning, budding

23
Q

How do sponges feed

A

Sponges feed by filtering water, trapping particles and digesting nutrients

24
Q

How do sponges defend themselves

A

They produce compounds that are toxic to other organisms

25
Q

Why are sponges useful?

A

Take out bacteria from the water, filters out excess nitrogen that can harm the environment, breaks down old shells, humans use it for bathing, cleaning, used in medicine.

26
Q

THE CNIDARIANS (give examples)

A

Jellyfish, Hydra, Anemones

27
Q

Cnidarians are the first…

A

Animals to move and become active predators, to have nerves (around the mouth)

28
Q

How many tissue layers, name

A

3, endoderm, mesoglea, and ectoderm

29
Q

Cnidoblast

A

Stinging cell of jellyfish, contains nematocyst (threaded barb thing)

30
Q

Can it move on its own?

A

it has basic muscles to undulate

31
Q

gastrovascular cavity

A

Cavity for food digestion

32
Q

How do Cnidarians digest

A

produces enzymes that can digest large prey. Eliminates waste through diffusion

33
Q

cnidarians reproduction

A

both sexual (medusa relasing gametes) and asexual (budding)

34
Q

Class Hydrozoa

A

Ex. Hydra, Portugese man o war

35

Properties of class hydrozoa

A

polyp is usually dominant
mostly marine
most are male or female (some hermaohrodites)
colonial or solitary

36
Q

Class Scyphozoa

A

Ex. Jelllyfish

37
Q

Properties of class scyphozoa

A

Medusa Dominant
Entierly marine (saltwater)

38
Q

Class anthazoan

A

Sea anemones and corals

39
Q

Properties of class anthazoan

A

Only polyp form
Sessile
rely on symbionts for food (symbiotic relationship)
Coral produces calcium carbonate skeleton

40
Q

Phylum Platyhelminthes

A

Ex. Flatworms

41
Q

Properties of Platyhelminthes

A

Lives in fresh or salt water
First to show formation of head (cephization)
3 layers (ecto, endo, and mesoderm)
first with basic organ systems

42
Q

What are planaria?

A

Free living living flatworms, under phylum platyhelmintes

43
Q

class turbellaria

A

Free living freshwater wormj

44
Q

Properties of turbellaria

A

1-6 cm, no body cavity
simple brain, two nerve cords
eyespots and auricles to detect ligth and chemicals

45
Q

Reproduction for turbellaria

A

Asexual (splits) and sexual reproduction (penis fencing)

46
Q

Digestion for turbellaria

A

Mouth at middle of the body
pharynx
gastrovascular cavity
excess water pumped out through flame cells

47
Q

Respiration for turbellaria

A

Gases diffuses through cell walls

48
Q

Class trematoda

A

Ex. Blood Flukes

49
Q

Properties of trematoda

A

internal parasites
suckers attach to host
well devloped life cycle
(CHINESE LIVER FLUKE, REMEMBER)

50
Q

Class cestoda

A

Ex. Tapeworm

51
Q

Properties of cestoda

A

All parasitic
eats a lot, grows a lot
latches on with sharp hooks
absorbs nutrients through body walls
well developed reproductive systems
poorly developed digestive and nervous systems

52
Q

PHYLUM NEMATODA

A

AKA roundworms

53
Q

Nematoda are the first to have…

A

Fully developed digestive systems

54
Q

Properties of the phylum nematoda

A

2 openings, mouth and anus, for continuous eating
have ganglia, but no brain
senses chemicals from prey and hosts
hermaphrodites
uses diffusion for respiration
NEMATODA ARE MOSTLY FREE LIVING, BUT SOME ARE PARASITIC
complicated lifecycle, may need more than 1 host
has an organ bag, aka a pseudocoelom
