  • Question 1
    1 / -0
    Which covers largest number of organisms?
    Solution
    The correct hierarchy of classification of various taxa in descending order is given by :
    Kingdom → Phylum → Class → Order → Family → Genus → Species
    The kingdom is the highest level of classification and contains the maximum number of species followed by Phylum while species being the most specific having minimum number of members.
    So, the correct option is 'Phylum'. 
  • Question 2
    1 / -0
    ICBN stands for ?
    Solution

    Correct option: B
    Explanation:

    • ICBN stands for - International Code of Botanical Nomenclature. 
    • It is the set of rules and recommendations for naming plants, fungi, and algae as the ICBN applies not only to plants, as they are now defined, but also to other organisms traditionally studied by botanists.
    So, the correct option is option B.
  • Question 3
    1 / -0
    A group of plants or animals with similar characters of any rank is
    Solution
    A group of plants or animals with similar characters of any rank is Taxon.
    Taxa are arranged in a hierarchy from kingdom to subspecies, a given taxon ordinarily includes several taxa of lower rank. 
    So, the correct answer is 'Taxon'
  • Question 4
    1 / -0

    Species is a group of organisms that _________ and breed is a group of animals of _______
    Solution
    Species are defined as a group of organisms that have similar characteristics and can interbreed to produce fertile offsprings. whereas A group of animals of the same species related by descent and having characteristics that are different from the other groups in the same species are said to belong to a breed.
    So, the correct answer is option C 'Can inter-breed, same species'. 
  • Question 5
    1 / -0
    Individuals of one population can inter-breed with individuals of another population only if they belong to the same _____
    Solution
    Species are organisms with similar characteristics and their interbreeding results in production of fertile offsprings.
    So, the correct answer is 'Species'
  • Question 6
    1 / -0
    Which of the following is not a taxon but category ?
    Solution
    The division is a category yet not a taxon. Basically Taxon is a gathering of at least one population of a life or animals seen by taxonomists to outline a unit. Taxonomic classification is commonly used equally with the term ordered position or ordered rank. The major arranged orders are a kingdom, phylum, class, order, family, genus, and species. A class or classification can contain at any rate one taxa.
    So, the correct answer is 'Division'
  • Question 7
    1 / -0
    The branch of botany concerned with the classification, nomenclature and identification of plants is known as
    Solution
    Systematics is a branch of botany which deals with the study of plants. It is concerned with the study of the diversity of plants and the evolutionary relationships on the basis of anatomy, physiology, etc. It is used for the classification of the organisms/plants on the basis of hierarchical ranks. 
    Thus, the correct answer is option A. 
  • Question 8
    1 / -0
    If a botanist has to nomenclate a similar species, he will use
    Solution
    For a similar Species isotype is done of a plant as holotype which means (reference specimen)
    In this process a specimen is collected from the same plant at the same time and this duplicate specimen are often kept in several Institute. So if a botanist has to nomenclature a similar species he will used isotype.
    So, the correct answer is 'Isotype'
  • Question 9
    1 / -0
    Which of the following taxonomical ranks contain organisms least similar to the other similar taxon?
    Solution
    Species is the lowest taxonomic category which is a group of a population that can interbreed and reproduce. The organisms in the two species are least similar to each other. Genus is next higher category above the level of species which are related to each other and have fewer characters in common. The family represents groups of related genera. The class represents organisms of related orders.
    Thus, the correct answer is option D. 
  • Question 10
    1 / -0
    Binomial nomenclature system of Linnaeus means that every organism has
    Solution
    The binomial nomenclature system is a system of naming and classifying organism in which two terms are used to denote a species of living organism and it has two parts, the genus name and the species name (specific epithet), e.g., Homo sapiens, the name of the human species. 
    Thus, the correct answer is the option (D), '    One scientific name with generic and other with the specific epithet'.
