CHAPTER 1

The scientific naming of organisms is known as?

• Identification

• Classification

• Nomenclature

• Taxonomy

Answer explanation

The scientific naming of organisms is specifically referred to as nomenclature. It involves assigning names to species based on established rules, distinguishing it from classification and taxonomy, which involve broader categorization.

The system of giving a name with two components is called?

• Monomial nomenclature

• Binomial nomenclature

• Trinomial nomenclature

• Binary naming

Answer explanation

The system of naming organisms with two components is known as binomial nomenclature. This method, developed by Carl Linnaeus, uses the genus and species names to uniquely identify species.

In the scientific name Mangifera indica, Mangifera represents?

• Species

• Family

• Genus

• Order

Answer explanation

In the scientific name Mangifera indica, 'Mangifera' is the genus, which is a higher taxonomic rank than species. Therefore, the correct answer is 'Genus'.

Which of the following is true about biological names?

• They are written in English

• They are always underlined in print

• They are Latinised and written in italics

• They can be written in any language

Answer explanation

Biological names are standardized in scientific contexts, using Latinized terms and italicization to ensure clarity and consistency across languages. Therefore, the correct statement is that they are Latinised and written in italics.

Which organization provides the rules for naming plants?

• IUCN

• ICZN

• ICBN

• WHO

Answer explanation

The ICBN (International Code of Botanical Nomenclature) provides the rules for naming plants. The other organizations listed, such as IUCN and WHO, focus on conservation and health, respectively.

Which of the following statements regarding binomial nomenclature is incorrect?

• Both the words are printed in italics when typed.

• The generic name begins with a capital letter.

• The specific epithet is written with a capital letter.

• Both words are underlined separately when handwritten.

Answer explanation

The incorrect statement is that the specific epithet is written with a capital letter. In binomial nomenclature, the specific epithet is always written in lowercase.

Which of the following combinations is correctly matched?

• ICBN – Zoological Nomenclature

• ICZN – Botanical Nomenclature

• ICBN – Plants

• ICZN – Plants and Animals

Answer explanation

The correct match is ICBN – Plants, as ICBN stands for International Code of Botanical Nomenclature, which governs the naming of plants. ICZN, on the other hand, refers to the International Code of Zoological Nomenclature for animals.

Which feature does not apply to living organisms?

• Growth from inside

• Response to stimuli

• Reproduction

• Crystallization

Answer explanation

Crystallization is a process that forms solid crystals from a solution, which does not occur in living organisms. In contrast, growth from inside, response to stimuli, and reproduction are essential characteristics of life.

Carolus Linnaeus is famous for?

• Discovering cell theory

• Developing the classification of animals based on habitat

• Describing DNA structure

• Introducing binomial nomenclature

Answer explanation

Carolus Linnaeus is famous for introducing binomial nomenclature, a system for naming organisms using two terms, which is fundamental in the field of taxonomy.

Which of the following correctly defines taxonomy?

• Study of classification, naming, and identification of organisms

• Study of fossils

• Study of cells and tissues

• Study of evolution

Answer explanation

Taxonomy is the science of classifying, naming, and identifying organisms. It encompasses the organization of living things into categories based on shared characteristics, making the first choice the correct definition.
