List out the functions of a museum.

Can you identify the correct sequence of taxonomical categories?

1. Species → Order → Phylum → Kingdom
2. Genus → Species → Order → Kingdom
3. Species → Genus → Order → Phylum

Try to collect all the currently accepted meanings for the word ‘species’. Discuss with your teacher the meaning of species in case of higher plants and animals on one hand, and bacteria on the other hand.

Illustrate the taxonomical hierarchy with suitable examples of a plant and an animal.

The process to standardize the naming of living organisms is called nomenclature. Obviously, the nomenclature is only possible when the organism is described correctly and we know to what organism the name is attached to this is identification. The system of providing scientific name with two components is called Binomial Nomenclature. The scientific name ensures that each organism is identified by only one name all across the world. They also ensures that such a name has not been used for any other known organism. Scientific names for plants are provided in ICBN and for animals, in ICZN.
