Taxonomy Flashcards
1
Q
Order of classifications
A
Domain - Kingdom - Phylum - Class - Order - Family - Genus - Species
2
Q
What are the three domains?
A
Archaea, Bacteria, Eukarya
3
Q
Archaea
A
- Prokaryotes, cell wall, cell membrane (glycerol-ether lipids)
- Unique metabolism/translation
4
Q
Eubacteria
A
- Single 2X stranded circular DNA, cell walls
- Cyanobacteria
5
Q
Protista
A
- Primitive eukaryote with no differentiated tissue
- E.g. Euglena
- Protozoa, Algae, Slime molds
6
Q
Fungi
A
- Chitin cell walls, eukaryote, heterotroph, saprophytic/parasitic
- Asexual sporulation or intricate sexual process
7
Q
Bryophytes
A
- No xylem, flagellated sperm
- Gametophyte is dominant stage
- Mosses, Liverworts
8
Q
Tracheophytes
A
- Xylem/phloem
- Radial symmetry along vertical axis
- Deep roots
- Sporophyte is dominant
9
Q
Non-seed Bearing
A
- Pterophytes (ferns)
- Lycophytes (club mosses)
10
Q
Angiosperms
A
- Anther of male stamen –> microspores
- Ovary of female postil –> megaspores
11
Q
Dicotyledons
A
-Net-veined leaves, vascular bundles, can be woody, two seed leaves, flower in multiples of 4 or 5
12
Q
Monocotyledons
A
- Parallel veins, scattered vascular bundles, single seed leaf
- No cambium therefore nonwoody
- Flower in multiples of 3
- Grasses
13
Q
Gymnosperms
A
- Naked-seeded plants
- Specialized cambium –> secondary growth of secondary xylem/phloem
- Conifers produce two cones (female/male)
14
Q
Porifera
A
-2 layers of cells, pores, low specialization
15
Q
Cnidara
A
- Digestive sac sealed at one end
- 2 germ layers
