Taxonomy

Taxonomy is the science of classifying and naming organisms based on shared characteristics.

The three domains of life are Archaea, Bacteria, and Eukarya.

Archaea are single-celled organisms that often live in extreme environments and have unique biochemistry.

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Carl Linnaeus developed the binomial nomenclature system for naming organisms.

Binomial nomenclature is a two-part naming system for organisms, consisting of the genus name and species name.

A kingdom is a high-level taxonomic category that groups together related organisms.

The five kingdoms are Monera, Protista, Fungi, Plantae, and Animalia.

Fungi are eukaryotic organisms that absorb nutrients from their environment and have cell walls made of chitin.

Mammals are distinguished by their ability to produce milk and typically do not lay eggs (except for monotremes).
