Classification and Evolution Flashcards
Archaea
- Prokaryotic
- single-celled
- proteins associated with DNA
- cell walls not made out of peptidoglycan
- live in extreme
environments
Eubacteria
- Prokaryotic
- single-celled
- naked DNA
cell walls made of
peptidoglycan - bacteria
Eukarya
- Eukaryotic
- single-celled and multicellular organisms with membrane-bound organelles and DNA associated with histone proteins
- Includes: Fungi (yeast, molds, mushrooms), Plants, Animals, and Protists
taxa order
King Philip Came Over For Good Soup
Kingdom, Phylum, Class, Order, Family, Genus, Species
Plant phyla
phylum Bryophyta, phylum Filicophyta, phylum Angiospermophyta, Phylum Coniferophyta
Phylum Bryophyta: Non-vascular Plants
small; lacking leaves/ stems; no xylem/ phloem tissue; reproduce using spores – ex: mosses & liverworts
Phylum Filicophyta
have pinnate leaves (leaflets on stalks); reproduce using spores released from sori – ex: ferns
Phylum Angiospermophyta
(“angiosperms”)
flowering plants
Phylum Coniferophyta
(“conifers/ gymnosperms”)
seeds are in cones (naked seeds)
Porifera
Asymmetrical Have pores no segmentation spicules for support sea sponge
cnidaria
radial symmetry mouth but no anus no segmentation stinging cells (cnidocytes) Jellyfish, coral, sea anemone
platyhelmintha
bilateral symmetry mouth but no anus no segmentation flattened body (SA:Vol ratio) Tapeworm, planaria
annelida
Bilateral symmetry mouth and anus segmented movie via peristalsis Earthworm, leech
Mollusca
Bilateral symmetry mouth and anus non-visible (mantle and foot) may have a shell (made by mantle) snail, octopus, squid, bivalves
Arthropoda
Bilateral symmetry mouth and anus segmented exoskeleton (chitin) insects, spiders, crustaceans
Fish
Scales made out of bony plates external reproduction breathe through gills Ectothermic have a swim bladder
Amphibian
moist skin external reproduction breathe through simple lungs and via skin ectothermic larval start in water - adult on land
Reptile
scales made out of keratin internal reproduction (lays soft eggs) lungs with extensive folding ectothermic simple teeth with no living tissue
bird
feathers internal reproduction (lays hard eggs) lungs with bronchial tubes endothermic have wings and beaks with no teeth
Mammal
hair
internal reproduction - live births (except monotremes)
lungs with alveoli
endothermic
feed young with milk from the mammary gland
define evolution
Evolution is the process of cumulative change (in the heritable characteristics of a population) over time
