In a flowering plant, archesporium gives rise to
Wall and the tapetum
Only tapetum and sporogenous cells
Only the wall of the sporangium
Both wall and the sporogenous cells
(d) The archesporial cells divide periclinally, cutting off primary parietal layer (forming wall later on) towards the outer side and primary sporogenous cells towards the inner side.
Biosystematics aims at
a) Biosystematics aims at morphological delimitation of taxa but incorporates evidences from Genetics, Cytology, Anatomy, Palynology, Chemistry, Physiology, etc.
Phenetic classification of organism is based on
a) 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.
Systematic botany means
d) The term ‘Systematic Botany’ refers to the methodical study of plants, dealing with identification, naming and classification.
Which taxonomical aid provide all information about a particular taxon like order or family
c) Taxonomic aid monograph is treatise having complete information about a particular rank level of a taxonomic category. Key or taxonomic key contain list of traits or characters and their alternate which are helpful in taxonomic studies. Catalogue registers the species present in a particular place with brief description.
Binomial system of nomenclature was given by
b) 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.
