Solution:
i) Phylum: Phylum is a unit or a category, which is higher than class and lower in rank than kingdom. It consists of one or more related classes with some common features and phenotypic resemblance. In botany the term division is used for phylum.
ii) Class: Class is a taxonomic category higher in rank than order and comes under phylum. It consists of one or more related orders with some common features in morphological characters .
iii) Family: Family is a taxonomic category having one or more related genera with some similar common features and comes under order.
iv) Order: Order or Cohort is a category consisting of one or more related families having some common or correlated phenotypic characters.
v) Genus: genus or plural genera is a biological classification ranking between family and species. It consists of morphologically or phylogenetically related species or a single isolated species exhibiting unusual distinction (monotypic genus).
The genus name is the first word in a binomial nomenclature (the species name is the second word) and is always capitalised.
