Introduction to Taxonomy definitions Flashcards

The branch of biology focused on the systematic naming, describing, and classifying of organisms based on shared characteristics and evolutionary history.

The highest taxonomic rank, categorizing all life into three groups: Bacteria, Archaea, and Eukarya, based on genetic and cellular differences.

A domain of prokaryotic microorganisms characterized by a lack of a membrane-bound nucleus, peptidoglycan cell walls, and diverse metabolic pathways.

Microorganisms distinct from bacteria and eukaryotes, often found in extreme environments, with unique genetic and biochemical characteristics.

Organisms with complex cells containing a nucleus and membrane-bound organelles, including animals, plants, fungi, and protists.

An organism from which two or more species evolved, representing their most recent shared lineage.

Organisms that produce their own food using light or chemical energy, serving as primary producers in ecosystems.

Organisms that obtain energy by consuming other organisms, rather than producing their own food through photosynthesis or chemosynthesis.

Organisms that produce their own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Organisms that obtain energy by consuming other organisms, rather than producing their own food.
