Study Notes
Binomial Nomenclature
- The genus name is the only term that is capitalized.
Taxonomic Hierarchy
- Several different classes are grouped together to form a phylum.
- The two highest taxonomic categories in the Linnaean system are phylum and kingdom.
Animal Classification
- Warm-blooded animals with body hair that produce milk for their young belong to the class Mammalia.
Evolutionary Classification
- A monophyletic group contains one ancestor along with all its descendants.
- The goal of evolutionary classification is to organize organisms based on phylogenetic relationships rather than solely on physical traits.
Common Characteristics of Organisms
- All organisms utilize DNA to transmit genetic information.
Historical Taxonomy
- In Linnaeus's era, life was classified into two kingdoms: animals and plants.
Nutrition and Energy
- Heterotrophs derive energy for life processes from the chemical energy stored in organic compounds.
Domains and Kingdoms
- The domain Eukarya includes the kingdoms Protista, Fungi, Plantae, and Animalia.
- Fungi are classified as heterotrophic, distinguishing them from plants.
Species and Genera
- A genus encompasses multiple similar species.
- The second part of the scientific name (e.g., saccharum in Acer saccharum) identifies the species.
Derived Characters
- A derived character is a trait that originated in the most recent common ancestor of a lineage and is inherited by its descendants.
Classification Errors
- Eukarya is not one of the six kingdoms of life; it represents a domain.
- Protista is incorrectly cited as a domain of life.
Organism Classification
- An organism characterized as a multicellular heterotroph made up of eukaryotic cells with no cell walls is classified as an animal.
- Organisms in the kingdom Plantae are autotrophic, indicating they produce their own food.
