Q. 1Biosystematics aims at

A. 1a) Biosystematics aims at morphological delimitation of taxa but incorporates evidences from Genetics, Cytology, Anatomy, Palynology, Chemistry, Physiology, etc.

Q. 2Phenetic classification of organism is based on

A. 2a) Phenetics (Gr. Phainein= to appear; the term phenotypes is derived from this same root) dedicates taxonomic affinities entirely on the basis of measurable similarities and differences.

Q. 3Systematic botany means

A. 3d) The term ‘Systematic Botany’ refers to the methodical study of plants, dealing with identification, naming and classification.

Q. 4Which taxonomical aid provide all information about a particular taxon like order or family

Q. 5Binomial system of nomenclature was given by

A. 5b) Carolus Linnaeus (1707-1778) employed binomial system of nomenclature in the first edition of his book ‘Species Plantarum’ in 1753. According to which, the plant name is consisted of two Latin words. The first of which is generic name and the second is specific name.
