Flashcards in Taxonomy Deck (22):
1

Order of classifications

Domain - Kingdom - Phylum - Class - Order - Family - Genus - Species

2

What are the three domains?

Archaea, Bacteria, Eukarya

3

Archaea

-Prokaryotes, cell wall, cell membrane (glycerol-ether lipids)
-Unique metabolism/translation

4

Eubacteria

-Single 2X stranded circular DNA, cell walls
-Cyanobacteria

5

Protista

-Primitive eukaryote with no differentiated tissue
-E.g. Euglena
-Protozoa, Algae, Slime molds

6

Fungi

-Chitin cell walls, eukaryote, heterotroph, saprophytic/parasitic
-Asexual sporulation or intricate sexual process

7

Bryophytes

-No xylem, flagellated sperm
-Gametophyte is dominant stage
-Mosses, Liverworts

8

Tracheophytes

-Xylem/phloem
-Radial symmetry along vertical axis
-Deep roots
-Sporophyte is dominant

9

Non-seed Bearing

-Pterophytes (ferns)
-Lycophytes (club mosses)

10

Angiosperms

-Anther of male stamen --> microspores
-Ovary of female postil --> megaspores

11

Dicotyledons

-Net-veined leaves, vascular bundles, can be woody, two seed leaves, flower in multiples of 4 or 5

12

Monocotyledons

-Parallel veins, scattered vascular bundles, single seed leaf
-No cambium therefore nonwoody
-Flower in multiples of 3
-Grasses

13

Gymnosperms

-Naked-seeded plants
-Specialized cambium --> secondary growth of secondary xylem/phloem
-Conifers produce two cones (female/male)

14

Porifera

-2 layers of cells, pores, low specialization

15

Cnidara

-Digestive sac sealed at one end
-2 germ layers

16

Platyhelminthes

-Bilateral symmetry
-3 germ layers
-No circulatory system
-Eyes, Anterior brain ganglion, longitudinal nerve cords

17

Nematoda

-Long digestive tubes and anuses
-3 germs layers
-No circulatory system
-Nerve cord/nerve ring

18

Annelida

-Segmented worm
-Coelom
-Nervous, circulatory, excretory

19

Mollusca

-Soft-bodied, exoskeletons
-Gills, chambered hearts, blood sinuses, ventral nerve cords

20

Arthropoda

-Contain more species than any other phlyum
-Jointed appendages
-Chitinous exoskeletons
-Insects, Arachnids, Crustaceans

21

Echinodermata

-Spiny, radially symmetrical, water-vascular system, regeneration
-Starfish/sea urchin

22

Viruses

-Nonliving, DNA/RNA, bacteriphage, lytic/lysogenic
