Question

Amongst the various levels of classification of plants in order of increasing similarity, which taxa come before ‘genus’ and after ‘class’ respectively?

• A.
  Division and species
• B.
  Family and order
• C.
  Order and division
• D.
  Division and family

Answer 1

The correct option is B

Family and order
In the taxonomic hierarchy, when we move down from kingdom to species, the level of similarity increases.

Thus, according to increasing similarity, the hierarchical order in plants will be:

Kingdom → Division → Class → Order → Family → Genus → (least similar)
Species (most similar)

According to this order, the taxa that comes before genus is ‘Family’ and after class is ‘Order’.
