SBI3U: Diversity and Kingdoms
questions and answers graded A+
Taxonomy - correct answer ✔✔The study of identification, classification, and naming of
organisms
Taxonomic key is a method to identify organisms
Species Concept - correct answer ✔✔Ways to define a species. It is used to identify species
Morphological Species Concept - correct answer ✔✔Defines with a focus on morphology - the
body shape size structural features etc. Studies the relationships of structures in organisms.
Biological Species Concept - correct answer ✔✔Defines with a focus on whether two organisms
can produce fertile offspring
Phylogenetic Species concept - correct answer ✔✔Defines with a focus on evolutionary history
Advantages of each species concept - correct answer ✔✔Morphology - Simplicity and widely
used
Biological - Simplicity and widely used
Phylogenetic - Can be applied to extinct species; Has information about relationships of
organisms based on DNA.
, Disadvantages of each species concept - correct answer ✔✔Morphology - The threshold to
decide whether variance between individuals decides if individuals are of different species, as
all individuals are slightly unique.
Biological - Cannot be applied with asexually reproducing organisms; fossils and extinct
organisms. The two populations of organisms, we need to analyze can be separated.
Phylogenetic - Evolutionary histories are not known for all species
Binomial nomenclature - correct answer ✔✔1. Handwritten: underlined Genus species
2. Online: italics Genus species
Classifying species - correct answer ✔✔the grouping of organisms based on a set of criteria
which helps to indicate evolutionary relationships
heirarchical classification - correct answer ✔✔The method of classifying organisms where
species are arranged in categories from most general to most specific.
Taxonomic Categories
Taxonomic Categories - correct answer ✔✔Species are classified by assiging it membership in 8
nested categories. Domain, Kingdom, Phylum, Class, Order, Family, Genes, Species
Rank - correct answer ✔✔Each of the eight taxonomic categories
Taxon - correct answer ✔✔Names group of organisms sush as phylum Chordata
Evidence of relationships among species - correct answer ✔✔Anatomical
