Q

What are three special adaptations of Dugesia?

A

(1) cephalized nervous system
(2) highly branched gastrovascular cavity
(3) mesoderm

25
Q

Describe Dugesia ingestion.

A

The pharynx is everted out of the body and searches for food. Food particles are sucked up through the mouth/anus and deposited in highly branched gastrovascular cavity for digestion.

26
Q

What symmetry does Hydra have? What about Dugesia?

A

Hydra: radial
Dugesia: bilateral

27
Q

Define the ectoderm, endoderm and mesoderm.

A

Ectoderm- the outermost germ layer of an organism
Endoderm-the innermost layer of an organism and gives rise to internal organs
Mesoderm- between the ectoderm and endoderm and gives rise to skeletal structures, muscles, or linings

28
Q

Define coelom, acoelomate, pseudocoelomate, and coelomate

A

A body cavity within the mesoderm.
Acoelomate means body cavity is absent
pseudocoelomate body cavity is partly lined and no coelom
coelomate means completely lined

29
Q

What are some friends of Dugesia?

A

Tapeworm, chinese liver fluke

30
Q

True or false? Dugesia have a coelom.

A

False

31
Q

What is the subkingdom and phylum of Trubatrix?

A

Eumetazoa Nematoda

32
Q

What is the common name of Turbatrix?

A

vinegar eelworm

33
Q

What is the symmetry and body plan of Turbatrix?

A

bilateral; triploblastic

34
Q

What is the habitat of Turbatrix?

A

low pH waters

35
Q

What does Turbatrix eat?

A

bacteria and fungi

36
Q

Skeleton of Turbatrix?

A

hydrostatic

37
Q

True or false? Turbatrix has a protein cuticle for protection.

A

true

38
Q

What is the subkingdom and phylum of Lumbricus?

A

Eumetazoa Annelida

39
Q

Lumbricus has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.

A

bilateral, triploblastic coelomate, tubular

40
Q

What are three adaptations of Lumbricus?

A

Septae (bristles for traction)
Segmentation
cuticle for protection

41
Q

What are two friends of Lumbricus?

A

marine sandworm and leech

42
Q

What is the subkingdom, phylum, common name of Pomacea?

A

Eumetazoa Mollusca; apple snail or mystery snail

43
Q

Pomacea has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.

A

bilateral, triploblastic coelomate, tubular

44
Q

What are three adaptations of Pomacea?

A

(1) radula with teeth for eating plants and scraping food
(2) gills and lungs
(3) separate male and female sexes

45
Q

What are some friends of Pomacea?

A

clam, octopus, squid, oysters, mussels

46
Q

What is the subkingdom, phylum, and common name of Cambarus?

A

Metazoa Arthropoda, crayfish

47
Q

What is the habitat of Cambarus?

A

freshwater

48
Q

What is the skeletal structure of Cambarus?

A

chitinous exoskeleton

49
Q

An adaptation of Cambarus is they have ______ body parts.

A

Specialized

50
Q

Cambarus has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.

A

bilateral, triploblastic coelomate, tubular

51
Q

Cambarus eats…

A

small animals and detritus

52
Q

What are some friends of Cambarus?

A

insects, spiders, ticks, shrimp, centipede, grasshopper, crab

53
Q

Describe the bodily structure of Cambarus.

A

Two pincers attached to the specialized limbs called chelipeds. Two antennae, mouth parts, and gills which are located under the exoskeleton of the cephalothorax (middle body). This is attached to the abdomen which houses eight walking legs. Next, on the underside of the tail are the swimming legs. Males have two gonopods and six pleopods. Females have ten pleopods but the anterior pair are very small. Lastly is the tail fan that is made up of center telson and uropods on the sides.

54
Q

Describe the how Grantia filter feeds.

A

The internal cavity of Grantia called spongocel is lined with flagellated cells (choanocytes) that draw water in along with fine particles and tiny organisms through tiny pores in the body wall. Food particles are trapped on a layer of muciliage and transported into the cells for digestion. Water and wastes leave through the osculum–an opening at the top of the sponge. Amoebocytes carry nutrients to other parts of the organism.

55
Q

Describe the life cycle of Hydra.

A

(1) budding hydra develops gonads (male and female)
(2) sperm fertilizes the egg
(3) embryo develops
(4) young polyp arises
(5) becomes hydra

56
Q

Describe how Dugesia ingests food.

A

Food particles are sucked up through the mouth/anus and deposited in the highly branched gastrovascular cavity for digestion. Wastes are expelled through the mouth/anus.

57
Q

Describe the structure of Dugesia.

A

Dugesia has a head and tail end. On the anterior there are eyespots. Running down the body is a highly branched gastrovascular cavity, lateral nerve cord, and tranverse nerve. The

58
Q

What is the structure of Turbatrix?

A

At the anterior end, mouth then pharynx lead to intestine.

At the posterior end is the anus and slightly up on the body is the vulva that connects to a elongate ovary.
