Question

First phylogenetic system of plant classification was given by
A) Engler and pranti
B) Eichler
C) Oswald tippo
D) Bentham and hooker

Answer 1

Hint: Phylogenetics is a part of systematic that addresses the inference of relationship among the groups of organisms. These relationships are hypothesized by phylogenetic inference methods that evaluate heritable traits such as DNA sequences.

Complete answer:
->Phylogenetic system was based on dividing the plant kingdom into plants with concealed reproductive organs such as Cryptogamae (hidden reproduction) and Phanerogamae (visible reproduction). This system was developed in 1839-1887.
->Plant classification is basically done to place the plants into groups or categories to show relationships among them. Scientific classification follows the rules and system that standardize the group successive categories into a hierarchy as well as results.
Major classification of plants are:
>Pteridophytes- lack of seeds and flowers.
>Gymnosperms- seeds are completely uncoated and lack an ovary.
>Angiosperms- seeds are coated and developed in an organ or ovary.
>Thallophyta- microorganisms like algae, fungi, bacteria etc.
Advantages of phylogenetic classification
First,it tells something important about the organisms,its evolution history.
Second,it does not attempt to rank organisms.
This system is based on the evolution of life and classifies organisms on the basis of descent from a common ancestor.
Eichler was the first taxonomist to separate the Phanerogamae into Angiosperms and Gymnosperms. The Eichler system was the first phylogenetic system developed by August W. Eichler.

Hence the correct answer is Eichler.

Note: Plants that have flowers make up the largest group of Plantae Kingdom. After Eichler's death his colleague Adolf Engler continued its development. Plant classification is basically done to place the plants into groups or categories to show relationships among them.
