1: Intro Flashcards
Name the 6 kingdoms
- Monera
- Protista
- Fungi
- Plantae
- Animalia
- Archaebacteria
What organisms are in the kingdom Monera?
Prokaryotes
e.g bacteria, cyanobacteria, blue-green algae, spirochetes
What organisms are in the kingdom Protista?
Eukaryotic single-celled microorganisms
e.g Protozoa, diatoms, slime molds
What organisms are in the kingdom Fungi?
Molds, mushrooms, and yeasts - heterotrophic, multi-celled
What organisms are in the kingdom Plantae?
‘true’ plants e.g red, brown, and green algae, bryophytes and vascular plants. Photosynthetic, autotrophic, multi-celled
What organisms are in the kingdom Animalia?
Multicellular organisms. Ingestive, heterotrophic
What organisms are in the kingdom Archaebacteria?
Anaerobic, methane-producing microorganisms
How long ago did prokaryotes emerge?
3.4 BYA
How long ago did eukarya emerge?
2 BYA
How long ago did metazoans emerge?
(animals, multicellular): 875-650 MYA
Give 2 potential reasons for the cambrain explosion (there are many more)
Ecological e.g increased Oxygen
→ critical level of o2 allowed bigger/complex animals = predators
Evolution of the eye
→ predators/prey, mating displays = more diversity
What are 2 physical factors important in the evolution of animals?
- Changes in climate
- Continental drift
