Nomenclature, Identification and Binomial Nomenclature
Local names are warm and human, but they travel badly. A mango behind a Kerala school, the same species in a Brazilian market, and a herbarium sheet from 1890 may each carry a different label. Biology solves this friction with a single, stable, internationally legible naming system.
This quiz tests the foundations of that machinery:
- Why naming must be standardised so one organism has one name worldwide
- The meaning of nomenclature and why it depends on correct description
- Identification as knowing to which organism a name is attached
- The ICBN for plants and the ICZN for animals
- The two-component name: generic name plus specific epithet
- Carolus Linnaeus and the working example Mangifera indica
Work carefully through each item — the distinctions here underpin every later lesson on taxonomic categories and author citations.
Q1. Why is there a need to standardise the naming of living organisms?
Local names vary from place to place, even within a country, creating confusion. Standardisation ensures a particular organism is known by the same name all over the world.
Q2. The process of standardising the naming of living organisms, such that a particular organism is known by the same name all over the world, is called:
The source states that this process of standardising naming is called nomenclature.
Q3. According to the lesson, nomenclature or naming is only possible when:
Naming is possible only when the organism is described correctly and we know to what organism the name is attached.
Q4. Knowing to what organism a name is attached is referred to as:
The lesson states that knowing to what organism the name is attached is identification.
Q5. For plants, the scientific names are based on agreed principles and criteria provided in the:
For plants, scientific names are based on principles and criteria provided in the International Code for Botanical Nomenclature ##\ce{(ICBN)}##.
Q6. Animal taxonomists have evolved which code for naming animals?
Animal taxonomists evolved the International Code of Zoological Nomenclature (ICZN).
Q7. Which statement about scientific names is supported by the lesson?
The scientific names ensure that each organism has only one name.
Q8. The description of any organism should enable people:
The lesson states that description of any organism should enable people in any part of the world to arrive at the same name.
Q9. Each scientific name has two components. These are:
Each name has two components: the generic name and the specific epithet.
Q10. The system of providing a name with two components is called:
The system of providing a name with two components is called binomial nomenclature.
Q11. Binomial nomenclature was given by:
The lesson states that this naming system was given by Carolus Linnaeus and is practised by biologists all over the world.
Q12. The scientific name of mango is written as:
The scientific name of mango is written as Mangifera indica.
Q13. In the name Mangifera indica, what does Mangifera represent?
In this name, Mangifera represents the genus while indica is a particular species, or a specific epithet.
Q14. In the name Mangifera indica, indica represents:
In Mangifera indica, indica is a particular species, or a specific epithet.
Q15. Biological names are generally in Latin and are written in:
Biological names are generally in Latin and written in italics.
Q16. When a biological name is handwritten, how should the two words be treated?
When handwritten, both words in a biological name are separately underlined; when printed they are in italics, to indicate their Latin origin.
Q17. In a biological name, the first word represents the genus while the second component denotes the:
The first word represents the genus while the second component denotes the specific epithet.
Q18. Why are biological names Latinised or derived from Latin, irrespective of their origin?
Biological names are generally in Latin and written in italics; they are Latinised or derived from Latin irrespective of their origin.
Q19. Which of the following best distinguishes identification from nomenclature as presented in the lesson?
Identification is knowing to what organism the name is attached, while nomenclature is the process of standardising names. Naming is possible only when the organism is described correctly and identified.
Q20. The two-word format of binomial nomenclature was found convenient because:
The two-word format was found convenient, and scientific names ensure that each organism has only one name, acceptable to biologists all over the world.
