Plant Taxonomy

What are the main plant classification systems?

• Haeckelian system

• Mendelian system

• Darwinian system

• Linnaean system, APG system, Cronquist system

Who developed the system of binomial nomenclature?

• Louis Pasteur

• Gregor Mendel

• Carl Linnaeus

• Charles Darwin

What are the key characteristics of the Asteraceae family?

• Minimal agricultural use

• Single flower structure

• Composite flower heads, diverse plant forms, economic importance.

• Limited ecological roles

How does a phylogenetic tree represent plant relationships?

• A phylogenetic tree maps the nutritional value of different plants.

• A phylogenetic tree illustrates the size and shape of plant leaves.

• A phylogenetic tree shows the geographical distribution of plants.

• A phylogenetic tree shows evolutionary relationships among plants, indicating common ancestors and divergence points.

What are the levels of taxonomic hierarchy in plant classification?

• Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

• Domain, Kingdom, Phylum, Class, Order, Family, Subgenus, Species

• Kingdom, Division, Class, Order, Family, Tribe, Genus, Species

• Domain, Kingdom, Class, Order, Family, Subfamily, Genus, Species

What is the significance of the genus in binomial nomenclature?

• The genus is used to classify organisms based on their size.

• The genus signifies the group of closely related species in binomial nomenclature.

• The genus indicates the habitat of a species.

• The genus represents the age of a species in evolutionary terms.

How do phylogenetic trees differ from traditional classification systems?

• Phylogenetic trees focus on evolutionary relationships, while traditional classification systems are based on observable traits.

• Phylogenetic trees categorize organisms by their size, while traditional systems classify them by their habitat.

• Traditional classification systems emphasize evolutionary relationships, unlike phylogenetic trees which focus on physical characteristics.

• Phylogenetic trees are based on geographical distribution, while traditional systems focus on genetic data.

What is the highest rank in the taxonomic hierarchy?

• Phylum

• Kingdom

• Class

• Domain

Definition of monophyletic

• A group of organisms that includes all descendants of a common ancestor

• A group of organisms that includes diff. descendants of a common ancestor

Type Species: The species upon which the description of a genus is based, serving as the primary example of that genus.

• True

• False
