Taxonomy Flashcards
Monera (kingdom) includes: 2 other kingdoms
- Archaea
- Eubacteria
Compare and contrast Eubacteria and Archaea.
- Archaea:
- prokaryotes
- glycerol-ether lipids cell membranes
- extremophiles
- Eubacteria:
- prokaryotes
- morphological appearances cocci, bacilli, spirilla etc
- glycerol-ester lipid cell membranes
- i.e. cyanobacteria (photosynthetic pigments)
Protista: prokaryotic or eukaryotic?
Eukaryotes
- single celled, simple
3 phyla of Protista
Protozoa, Algae, Slime Molds
Protozoa
heterotrophic eukaryotes (protista) rhizopods move like animals with pseudopods i.e. amoebas locomotion
Algae
photosynthetic eukaryotes (protista)
(note blue-green algae (cyanobacteria) is not the same! they are prokaryotic)
-phytoplankton, kelp
Slime molds
eukaryotes (protista)
similar to fungi
- asexual reproduction - flagellated spores, fruiting bodies (unicellular)
Fungi
…similar to plants except
- chitin instead of cellulose cell walls
- non-photosynthetic
- heterotrophs not autotrophs (can be saprophytic)
- asexual sporulation
Plantae
- multicellular autotrophs
- non-motile
- photosynthetic
Bryophytes
- simple plants with FEW specialized organs
- no xylem
- generation alters between gametophyte (dominant) and sporophyte
i. e. mosses, liverwarts
Tracheophytes
- vascular plants
- xylem and phloem
A prokaryotic organism with flagella in hydrothermal vents is in which taxonomic category?
Archaea
Which taxonomic group has extremophiles?
archaea
Which group in Monera have flagella?
Archaea
Cyanobacteria belongs to what taxonomic group?
eubacteria
This organism is prokaryotic and has no organelles. What group is it?
eubacteria
This single celled organism is eukaryotic. What taxonomic group is it?
protista
Are protista heterotrophs or autotrophs?
Both
What types of protista are heterotrophs?
eukaryotes with the ability to move like animals
therefore, Protozoa (protist- zoa)
cilliary movement and pseudopods
What protists are autotrophs?
photosynthetic algae
i/e phytoplankton and kelp
