What is Classification
The process of arrangement of plants into distinct categories on the basis of desired characteristics is called as Classification.
It is basically the sorting of plant kingdom into groups that share some characteristics
ARTIFICIAL SYSTEM:
According to this system plant can be classified on the basis of easily observable characters like habit and floral characters.
Example
Linnaeus classification also known as SEXUAL Selection is an Artificial System of Classification.
NATURAL SYSTEM
This system of classification is based on such relationship between plants that might be naturally found.
Classification of plants on the bases of related affinities.
Classification of plants on basis of morphological characters just like are naturally present in environment.
Example: Bentham and Hooker
PHYLOGENETIC SYSTEM
Classification of plants on the basis of their evolutionary history using fossil records.
For this most accurate phylogenetic tree was selected
A phylogenetic tree is a tree like diagram that starts from a Common Ancestor with branches represent path of evolution.
Examples:
Eichler Classification
Englar and Prantl system
Richard von Wettstein
Charles Edwin Bessey
Hutchinson
Armon Takhtajan
Cronquist
Robert Thorne
RMT Dahlgren
PHENETIC SYSTEM
Classification on the basis of overall characters (Totality of Characters) or phenotype.
Here Phenetic means combined traits.
Plants are classified on basis of combination of traits
QUESTION
Phylogenetic system bring out
Reproductive strategies
Grouping according to morphological characteristics
grouping on basis of increasing complexities
grouping according to evolutionary trends
