Study Notes

Fungi

Heterotrophic organisms with cell walls made of chitin.

Eubacteria

Prokaryotic organisms characterized by cell walls containing peptidoglycan.

Plantae

Multicellular autotrophs that possess cell walls made of cellulose, primarily involved in photosynthesis.

Archaebacteria

Prokaryotes with cell walls that do not contain peptidoglycan, often found in extreme environments.

Animalia

Multicellular eukaryotes lacking cell walls and chloroplasts, predominantly heterotrophic.

Protista

A diverse group of eukaryotic organisms that can be unicellular, colonial, or multicellular.

Taxonomy Concepts

Domain: The largest, most inclusive taxonomic group.
Organisms are classified into three domains: bacteria, archaea, and eukarya.
All members of the domain Eukarya are eukaryotes, which means they possess a defined nucleus.

Classification of Prokaryotes

To determine the domain of a prokaryote, one must identify if its cell wall contains peptidoglycan.
Prokaryotes with cell walls containing peptidoglycan belong to the domain Bacteria.
Prokaryotes found in extreme environments fall under the kingdom Archaebacteria.

Phylum Chordata

Includes species such as humans, snakes, and sharks.

Kingdom and Domain Relationships

The domain Eukarya encompasses four kingdoms: Protista, Plantae, Fungi, and Animalia.
Kingdom Protista consists of both unicellular and multicellular organisms.

Additional Organism Characteristics

Mushrooms are classified under the kingdom Fungi.
Kingdom Plantae is mainly composed of photosynthetic autotrophs.
Kingdom Animalia consists of multicellular heterotrophs.

Taxonomic Hierarchies

Organisms are divided into three domains.
Eubacteria is the kingdom comprising unicellular prokaryotes of the domain Bacteria.
Archaebacteria is the kingdom for prokaryotes that thrive in extreme conditions.

Taxonomic Specificity

The species taxon represents the most specific classification level.
The kingdom taxon represents the broadest classification level.
An order includes more species than a family.
The species taxon includes organisms that can interbreed successfully.

Overlapping Taxonomic Groups

Organisms belonging to the same family also share the same order, class, phylum, and kingdom.
Amphibia is a class that does not include mammals, so it does not contain animals with hair or fur.
