21
Q

No mitochondria, giardia trypanosomes (in dark), unicellular, chloroplasts!

22

Q

3 layers, DEUTEROSTOMES & PROTOSTOMES

Study These Flashcards
A

Triploblastic

25
molluscs/annelids/bryozoans, PROTOSTOMES, feeding structure (lophophore) & free-living larval stage (trochophore)
Lophotrochozoans
26
arthropods/nematodes, shed exoskeleton to grow
Ecdysozoans
27
echinoderms/hemichordates/vertebrates, mouth forms second
Deuterostomes
28
most successful animals, crustaceans (marine & terrestrial, lobster) /hexapods (terrestrial, insects) /myriapods (millipede) /chelicerates (horseshoe crab/spiders), most complex of ecdysozoans, body supported by exoskeleton (chitin), segmented body, jointed appendages
arthropods
29
limbs not jointed, inefficient, can survive decade after drying out, simpler ecdysozoans
Tardigrades
30
roundworms, no limbs, no segmentation, scavengers/predators/parasites, simpler ecdysozoan
nematodes
31
have a foot for locomotion, internal organs, gastropods (snail) /bivalves (clams)/ cephalopods (octopus), LOPHOTROCHOZOAN
molluscs
32
lophotrochozoan, earthworms/leeches, segmented bodies
annelids
33
lophotrochozoan, tapeworms/flukes, mostly parasites, simple bodies & lack digestive tracts
flatworms
34
Lophotrochozoan, ciliated corona-sweeps food into mouth, some species-only females
rotifers
35
lophotrochozoan, colonial
bryozoans
36
deuterostomes, radially symmetric, bilateral as larvae, move & feed using tube feet (starfish)
echinoderms
37
deuterostomes, hollow nerve cord, postanal tail (shark), notochord (flexible support), pharyngeal slit for gas exchange, lancelet/tunicates/vertebrates
chordates
38
Segmented body plan
metameric
39
deuterostomes, 1/2 are ray finned fish, possess jaws, can crawl on land, internal skeleton, vertebrae, bone (vs cartilage), breath air, terrestrial limbs, amniotic eggs
Vertabrates
40
land animals, amphibians/reptiles/mammals
tetrapods
41
moist skin, require water for eggs (no shell), wet habitats, frogs (no tail)/ salamanders/ caecilians (limbs lost)
amphibians
42
eggs withstand drying conditions, complex structures with regions for protecting embryo/ gas & waste exchange etc
amniotic eggs
43
reptiles & mammals, has eggs
amniotes
44
amniotic egg provides "private pond", scales (keratin vs bone like fish), epidermis more durable and water retentive, turtles/tuataras (not lizard)/squamates (snakes & lizards)/crocodilians/dinosaurs & birds
reptiles
45
Mammary glands, sweat glands, 4 chambered heart (vs 3), hair, teeth vary!, prototherians (lay eggs, platypus)/ marsupials (newborns to pouch, kangaroo & opossum)/ eutherians (more developed at birth, 20 major groups)
Mammals
46
produces cells that undergo meiosis in flowers, products=spores
sporophyte
47
produces gametes by mitosis
gametophyte
48
dominant gametophyte, small & live in moist env, mosses/liverworts/hornworts
nonvascular plants
49
dominant sporophyte, true roots, stem branches at tip (dichotomous), reproduce by spores, tracheids-conduct water over long distances & primitive cell
vascular plants
