Question

Which of the following is correctly matched with no exception with regard to plant classification?
A. Family Poaceae
B. Division Pteridophyta
C. Class Bryopsida
D. Genus Solanum

Answer 1

We all know that classification has made our work easy. The plants have been classified into Kingdom, Phylum, Class, Order, Family, Genus and Species. These have been given certain suffixes so that we can easily differentiate between each of these taxonomic categories.

Complete answer:
To know the correct answer to the question, we must be well aware of the suffixes which are used to name the different taxonomic groups.
Plants and animals are classified into groups based on their characteristics. The highest or more precisely the largest unit of classification is the kingdom. The kingdom is divided into many phyla. These phyla are further divided into classes. The classes into orders, order into family, family into genus and finally the genus into species. Therefore, the smallest unit of classification is the species.
To differentiate between these groups, each is given a particular suffix. This is done so that only by knowing the name we can find out whether it is the Phylum or the Class or the Order etc.
For example: For Class we use the suffix “phyceae” if we are talking about the algae while for other plants we use the suffix “sida”.
The suffix that we use for the division is “phyta”. For genus we use the suffix “um”.

Therefore, the correct answer to the question is option c i.e. Class Bryopsida.

Note: The easiest way to remember the hierarchy is:
