(31 cards)
What are Archaebacteria?
Prokaryotic, extremophiles, unicellular, autotrophs & heterotrophs.
What are Eubacteria?
Prokaryotes, unicellular, autotrophs & heterotrophs, chemical makeup different from archaebacteria, neutral conditions.
What are Protists?
Eukaryotic, autotrophs & heterotrophs, unicellular & multicellular, includes animal, fungus, and plant-like organisms, some beneficial, some cause disease.
What are Fungi?
Eukaryotes, mushrooms, mildew, mold, heterotrophic, cell wall, unicellular & multicellular.
What are Plantae?
Eukaryotes, multicellular, autotrophs.
What are Animalia?
Eukaryotes, multicellular, no cell wall, heterotrophs, capable of movement.
What is an autotroph?
An organism that makes its own food.
What is a heterotroph?
An organism that gets food from other sources.
What are prokaryotes?
Organisms that do not have a nucleus.
What are eukaryotes?
Organisms that have a nucleus.
What is unicellular?
Made of only one cell.
What is multicellular?
Made of more than one cell; have cells with special functions.
What is a kingdom?
The second highest taxonomic rank, just below domain.
What is a common ancestor?
An organism that multiple species share as an ancestor.
Why do biologists use classification?
To organize living things into groups so that organisms are easier to study.
Who was Carolus Linnaeus?
A Swedish scientist who came up with the naming system binomial nomenclature.
What is binomial nomenclature?
Linnaeus’s naming system which consists of a two-part name.
What are the seven levels of classification?
Kingdom, Phylum, Class, Order, Family, Genus, Species. King Phillip Came Over For Green Soup.
Which level of classification is the most specific?
The most specific level is ‘species.’
Which level of classification is the least specific?
The least specific level is ‘Kingdom.’
How do scientists classify different species?
They group different types of organisms based on their similarities.
Who was Charles Darwin?
A British Naturalist known for the theory about species changing over time (natural selection).
What is a phylogenetic tree?
A diagram that reflects how species or other groups evolved from a series of common ancestors.
What does it mean when two organisms are drawn closely together on a phylogenetic tree?
It indicates that two species are more related if they have a more recent common ancestor.
