Taxonomy Flashcards
Why plants like water so much
Osmosis is easier
No gravity
No desiccation (drying out)
Adaptive evolution
Looks like pitchfork/ trident
Common ancestor, no extinction, creates variation
Phletic evolution
One species diverges into two, but one goes extinct
Ex. Birds and dinosaurs
Co-evolution
No common ancestor, dec. variation(between two bc track each other),
Ex. Flowers and bees
Convergent
No common ancestors, no extinctions, never actually combine
Converge bc similarities in environ
Ex. Thermal regulation, aqua dynamics, penguins/seals
Divergent
Common ancestor, no extinction, split into two
Ex. Crocs and alligators
Types of domains (and number)
3- archaea, bacteria, eukarya,
Which domains prokaryotic?
*archaea
*bacteria
Eukarya
*=prokaryotic
Number and names of kingdoms
6- Fungi Animalia Plantae Archaebacteria Eubacteria Protista
Domain archae
Prokaryotic
Thermophiles
Extreme halophiles
Chemosynthetic and heterotrophic
Domain eubacteria
Prokaryotic Photosynthetic Heterotrophic "Normal" living conditions Often infectious Pepidoglycon cell wall
Domain eukarya
Eukaryotic cell
Cladistics
Method of classification based on establishing phylogenies (I.e. Getting at evolutionary relationships
Comparing shared ancestral and shared derived characters between sets of organisms
