Question

Phylogenetic system of angiosperm classification was given by
A. Hallier
B. Hutchinson
C. Takhtajan
D. All of the above

Answer 1

Phylogenetic system of angiosperm involves the classification of organisms on the basis of a descent from a common ancestor. It is focused on evolutionary ancestry.

Complete Answer:
Phylogeny is the developmental history of the population of related organisms. It is represented by a phylogenetic tree that demonstrates how species are linked to one another by shared ancestors. A clade is a collection of species that contains an ancestor and all its descendants.

Johannes Gottfried Hallier was the first to gather specimens of the Nepenthes clipeata pitcher plant. He is credited with the creation of a phylogenetic classification of flowering plants, which became popular as the Hallier method.
The Hutchinson system was published as "Families of flowering plants," organised according to the system based on their possible phylogeny. This description is based on the first edition of Volume 1: Dicotyledonae 1926 and Volume 2:- Monocotyledonae 1934. The Hutchinson method was one of the most influential reforms of taxonomy in the early twentieth century. Hutchinson is known for its twenty-four dicta on the classification of flowering plants.
In 1942, Takhtajan established a classification system for flowering plants, underlining the phylogenetic relationship between plants. This first attempt allowed the classification arrangement up to the orders of higher plants, based on the structural forms of gynoecium and placenta.

Thus, the correct answer is option ‘D’. i.e., All of the above.

Note: Angiosperms vary in a variety of respects from other seed plants. The distinctive features taken together have made angiosperms the most abundant and various land plants and the most commercially important group for humans.
