Test: The Living World - Diversity in the Living World (April 1) - NEET MCQ

• The first word in binomial nomenclature is the genus to which the organism belongs, and it is called the generic name.
• The second word is the name of the species to which the organism belongs, and it is called the specific epithet.

​Hence, the correct option is 'B' i.e. 'Genus and Species'.

Correct option is A. Genus Triticum, family Poaceae, order Poales, Class Monocotyledonae

Answer: A. Species, Genus, Family, Order, Class, Phylum, Kingdom

Solution: The correct order of taxonomic hierarchy from the lowest (most specific) to the highest (most general) category is Species, Genus, Family, Order, Class, Phylum (or Division for plants), and Kingdom. This hierarchical system allows biologists to organize and classify organisms in a structured manner, reflecting both evolutionary relationships and morphological similarities. An interesting fact about this system is that it was developed by Carl Linnaeus in the 18th century, and it remains the foundation of modern biological classification.

• External and internal structure, along with the structure of cell,
• Development process and ecological information of organisms are essential and form the basis of modern taxonomic studies.

Note: The process of classification of living organisms into different taxa is called taxonomy.

International Union of Pure and Applied Chemistry is for the nomenclature of organic compounds.

1. International Code of Botanical Nomenclature (ICBN)
2. International Code of Bacteriological Nomenclature (ICBN) and
3. International Code of Zoological Nomenclature (ICZN)

These are the three codes of nomenclature for living organisms.

Species constitute a group of phenotypically similar organisms with common ancestry that can interbreed freely to produce fertile progeny and hence, is considered the basic unit of classification. 

Two organisms are said to belong to same species if they can interbreed among themselves to produce fertile offspring. In the case of plants, seeds represent the embryonic structure of the plant which later develops into offspring. 
So, the correct option is 'Can reproduce freely with each other and form seeds'.

Both the statements are correct.

There are different languages and so are different regional names for an organism which creates a lot of confusion & miscommunication among people universally. Therefore, scientists came up with the idea of binomial nomenclature.

Binomial nomenclature is introduced to standardize the name of a living organism.

Nomenclature is a system to assign very specific and particular scientific names to an organism according to its structure, behaviour and features. A particular scientific name is assigned so as to be understood when referred irrespective of language barriers.

• Biological systematics is the study of the diversification of living forms from both the past and the present.
• It also exhibits the relationships among living things through time. 

Hence, the correct option is "C" i.e. Diversity of organisms and their relationships.

The word “Taxa” means classification. And the study of taxa is called as taxonomy. Taxonomy is the classification of animals into different taxa and helps us to study organisms easily.

Examples of Taxa:

• A taxon is a taxonomic group or taxonomic unit of any ranking. Each category is referred to as a unit of classification.
• There are seven main taxonomic ranks: kingdom, phylum, division, class, order, family, genus, species.
   

​Hence, the correct option is 'C' i.e. 'a taxonomic group of any ranking'.
