Introduction to Biological Classification

These flashcards cover key vocabulary terms and concepts related to biological classification and the three domains of life.

EOC

Variance

The difference in the number of different life forms that exist.

Classification

The process of organizing living things into groups based on similar characteristics.

Taxonomy

Eukarya

One of the three domains of life, consisting of organisms with eukaryotic cells.

Eubacteria

Archaebacteria

A kingdom of prokaryotic organisms that live in extreme environments.

Kingdoms of Eukarya

Includes four kingdoms: Protista, Fungi, Plantae, and Animalia.

Prokaryotes

Organisms that lack a membrane-bound nucleus, including Archaea and Bacteria.

Multicellular Organisms

Organisms that consist of more than one cell, typically found in the domain Eukarya.

Extreme Environments

Habitats such as hydrothermal vents or acidic hot springs where certain organisms, like Archaea, thrive.
