First recorded western scholar to propose a classification system of living beings.

Scientist who coined the terms Prokaryote and Eukaryote.

The scientific discipline of describing, classifying, and naming organisms.

The current taxonomic classification system includes ____ Domains and ____ Kingdoms of nature.

Phenetics is known as numerical taxonomy and is based on phenotypic similarities regardless of whether species share a direct common ancestor or not.

The difference between a phylogenetic tree and a cladogram is that the former groups species according to their physical similarities and the latter shows the evolutionary kinship of different species.

A phylogenetic systematists would say that dolphins are mammals and not elasmobranch fishes because they share characteristics with other mammals, and these can be traced back to a common ancestor.

Dichotomous keys are tools used to identify organisms based on definitions of morphological characters according to whether they have or do not have a certain trait.

Once a scientific name has been assigned to a species, it is definitive and cannot be changed.

Eukaryotic organisms with chitin-containing cell wall, mostly multicellular heterotrophs. They secrete enzymes for nutrient absorption.

Eukaryotic organisms that do not have a cell wall, they are multicellular heterotrophs.

Prokaryotic organisms whose cell wall contains peptidoglycan, autotrophic or heterotrophic.

Eukaryotic organisms with cell walls composed of cellulose, chloroplasts, and autotrophs.

Eukaryotic organisms, mostly unicellular heterotrophic, some photosynthetic unicellular or multicellular.

Prokaryotic organisms, usually extremophiles, genetically closer to eukaryotes, heterotrophic or autotrophic.
