Question

Systematics deals with –
(1) Classification
(2) Nomenclature
(3) Plant description
(4) Plant exploration
(5) All of the above

Answer 1

Hint: Biological systematics is the study of the past and current diversification of living forms, as well as the links between living entities over time. Evolutionary trees are used to represent relationships. Branching order and branch length are two components of phylogenies.

Complete answer:
To ensure uniformity in the system, nomenclature is the process of assigning a universal scientific name to a taxon based on international rules agreed upon by the ICBN/ICZN/ ICVN/ICNCP. The organisation of organisms into groups based on their similarities is known as classification.
Identification is the process of reorganising an unknown taxon by comparing it to previously identified taxa and assigning it the appropriate rank and location in the taxonomic hierarchy. A plant's taxonomic characteristics, which describe its similarities and differences with other closely related species, are listed in its description.
Systematics is a discipline of science concerned with the study of biological variety as well as comparative and phylogenetic relationships. Its goal is to produce an inventory of local, regional, and continental plant resources by identifying, nomenclature, describing, and classifying taxa. As a result, all of the supplied options are correct.
Researchers use the various fields of biological systematics to better understand the links between different organisms. These branches are utilised to determine modern-day systematics' applications and uses.

Note: Biological systematics uses three distinct branches to classify species. Biological statistics are used in numerical systematics, or biometry, to identify and classify creatures. Biochemical systematics analyses the material that makes up the live part of a cell, such as the nucleus, organelles, and cytoplasm, to classify and identify animals.
