Classification of the Living World — BIOLOGY STD 6 — Question

Linnaeus’ general plan of classification:
The two kingdoms – Plantae and Animalia were further categorised into smaller groups based on common characteristics. He established taxonomic ranks (different levels) where the group at the top level had the least number of common features. As the level progressed to lower levels, the organisms had more features in common.
These taxonomic levels are:

• Kingdom – All living organisms are divided into two kingdoms plarits and animals.
• Division/Phylum – The next taxonomic level in the plant kingdom is divisionand in the animal kingdom is phylum.
• Class – A phylum or division is further divided into many classes.
• Order – A class has a number of orders. >
• Family – Under an order, come many families. Organisms same family are very similar in structure.
• Genus – Each family is divided into many genera (singular : genus).
• Species – Each genus is further divided into several species. Members of same species resemble each other very closely and can reproduce among themselves.
