The highest taxonomic rank, specified based on the differences in their cellular and genetic structure.
Domain
Second highest in taxonomic rank, groups together all forms of life that share structural and functional characteristics.
Kingdom
Rank beneath kingdom, groups together organisms with similar ody plans on structure.
Phylum
Level below phylum, share even more specific characteristics.
Class
Beneath class, groups based on even more specific similarities in their characteristics and behaviors.
Order
Groups together with even more specific similarities, such as similar body structure and behaviors. Below Order.
Family
Several related species.
Genus
Most specific level of organism, representing a group of individuals that can interbreed and produce offspring in natural conditions.
Species
A unique two-part name given to each species of organism.
Scientific Name
Who is the Pioneer of Molecular Phylogeny who is a groundbreaking rRNA research in the 1970s challenging the traditional 5-kingdom system?
Carl Woese
The kingdom who lacks a nucleus and membrane-bound organelles. They thrive in extreme environments and inhabit hot springs.
Archaea
A single-celled organism that do not have nuclei. They use photosynthesis or chemosynthesis. Essential for nutrient cycling and aid in decomposition.
Bacteria
Contains a nucleus and have organelles. Includes algae and protozoa, slime molds are also included. They can be autotrophic or heterotrophic.
Protista
They have chitin cell walls. They obtain nutrients from others and break down organic matter. They return nutrients to the ecosystem.
Fungi
Multicellular organism and autotrophic. They use chlorophyll for energy conversion. They have cell walls. Vascular plants have transport system and non-vascular does not.
Plantae
Multicellular and heterotrophic, they lack cell walls. Collagen provides them support. They have diverse body plans: Vertebrates & Invertebrates.
