Chelicerata, Myriapoda, Crustacea, Hexapoda
29
Give an example of Subphylum Chelicerata (phylum Arthropoda)
Horseshoe crabs, spiders, mites, ticks, scorpions. Dioecious
30

shrimp, crabs, crayfish, isopods, pill bugs. biramous appendage (2 points at end of leg)
32
Give an example of Subphylum Hexapoda (phylum Arthropoda)
insects with 6 legs (ants, bees, etc)
33
What are main points of phylum Echinodermata?
Sea stars, cucumbers, sea urchins, sand dollars, brittle stars. Coelomate, deuterostomes with pentaradial symm. (5 points)
34

40
What are some unifying characteristics of animals?
heterotrophic, multicellular, typical life cycle is diplontic, complex tissue structures
41
What is a diplontic life cycle in animals?
somatic diploid cells and haploid gamete cells
42
What are the 4 types of animal tissues?
epithelial, muscle, connective, nervous
43
What is epithelial tissue?
cover & protect external & internal body surface
44
What is muscle tissue?
skeletal, smooth & cardiac
45
What is connective tissue?
bone, fat, tendons, blood, etc.
46
What is nervous tissue?
nerves, brain, spinal cord
47
What are some main points of animal reproduction?
Most undergo sexual repro. some asexual through budding or fragmentation
48
What is the pathway development of animal reproduction?
Zygote -> blastula -> gastrula - zygotes (fertilized eggs) develop through series of stages to form germ layers. - Blastopore can become anus (in deuterostomes) or mouth (in protostomes)
49
What are the 3 germ layers formed during gastrulation in animals that give rise to different body parts?
Endoderm - lining of digestive tract Mesoderm - bones, muscles, organs Ectoderm - skin, nerves
50
What are diploblasts?
animals with 2 layers (& a non-living middle layer)
51
Animals with 3 layers are considered what?
triploblasts
52
What is an acoelomate?
no body cavity
53
What is eucoelomate or coelomate?
true body cavity surrounded by mesoderm
54
What is pseudocoelomate?
body cavity b/w the endoderm and mesoderm
