Why are the classification systems changing every now and then?

Reproduction cannot be the defining characteristic of living organisms. Justify.

What is biology and as a student of biology how will you define life?

Why is death considered as regulatory process on the earth?

Define a taxon. Give some examples of taxa at different hierarchical levels.

In a given habitat we have 20 plant species and 20 animal species. Should we call this as ‘diversity’ or ‘biodiversity’? Justify your answer.

The number and kinds of organism is not constant. How do you explain this statement?

What is the difference between flora, fauna and vegetation? Eichhornia crassipes is called as an exotic species while Rauwolfia serpentina is an endemic species in India. What do these terms exotic and endemic refer to?

How will you define life as a biologist? What features make you different from non-living things?

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.

How is a key helpful in the identification and classification of an organism?

What are taxonomical aids? Give the importance of herbaria and museums. How are Botanical gardens and Zoological parks useful in conserving biodiversity?
