Q

What are three special adaptations of Dugesia?

A

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

25
Describe Dugesia ingestion.
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
What symmetry does Hydra have? What about Dugesia?
Hydra: radial Dugesia: bilateral
27
Define the ectoderm, endoderm and mesoderm.
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
Define coelom, acoelomate, pseudocoelomate, and coelomate
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
What are some friends of Dugesia?
Tapeworm, chinese liver fluke
30
True or false? Dugesia have a coelom.
False
31
What is the subkingdom and phylum of Trubatrix?
Eumetazoa Nematoda
32
What is the common name of Turbatrix?
vinegar eelworm
33
What is the symmetry and body plan of Turbatrix?
bilateral; triploblastic
34
What is the habitat of Turbatrix?
low pH waters
35
What does Turbatrix eat?
bacteria and fungi
36
Skeleton of Turbatrix?
hydrostatic
37
True or false? Turbatrix has a protein cuticle for protection.
true
38
What is the subkingdom and phylum of Lumbricus?
Eumetazoa Annelida
39
Lumbricus has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.
bilateral, triploblastic coelomate, tubular
40
What are three adaptations of Lumbricus?
Septae (bristles for traction) Segmentation cuticle for protection
41
What are two friends of Lumbricus?
marine sandworm and leech
42
What is the subkingdom, phylum, common name of Pomacea?
Eumetazoa Mollusca; apple snail or mystery snail
43
Pomacea has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.
bilateral, triploblastic coelomate, tubular
44
What are three adaptations of Pomacea?
(1) radula with teeth for eating plants and scraping food (2) gills and lungs (3) separate male and female sexes
45
What are some friends of Pomacea?
clam, octopus, squid, oysters, mussels
46
What is the subkingdom, phylum, and common name of Cambarus?
Metazoa Arthropoda, crayfish
47
What is the habitat of Cambarus?
freshwater
48
What is the skeletal structure of Cambarus?
chitinous exoskeleton
49
An adaptation of Cambarus is they have ______ body parts.
Specialized
50
Cambarus has ______ symmetry, ______ _______ bodyplan, and a _______ digestive system.
bilateral, triploblastic coelomate, tubular
51
Cambarus eats...
small animals and detritus
52
What are some friends of Cambarus?
insects, spiders, ticks, shrimp, centipede, grasshopper, crab
53
Describe the bodily structure of Cambarus.
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
Describe the how Grantia filter feeds.
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
Describe the life cycle of Hydra.
(1) budding hydra develops gonads (male and female) (2) sperm fertilizes the egg (3) embryo develops (4) young polyp arises (5) becomes hydra
56
Describe how Dugesia ingests food.
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
Describe the structure of Dugesia.
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
What is the structure of Turbatrix?
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.
