  1. True

  2. False

Show answer
Correct Option: B
Explanation:

The botanical garden is the specialized gardens have the collection of living plants for reference.  Plant species in these gardens are grown for identification purposes and each plant is labeled indicating its botanical/scientific name and its family. Whereas zoological park is for fauna.
So, the correct answer is option B.

  1. Museum

  2. Zoological park

  3. Herbarium

  4. Botanical garden

Show answer
Correct Option: C
Explanation:

The herbarium is a quick referral system in taxonomic studies. It is a collection of preserved plant specimens and associated data used for scientific study. So, the correct answer is (C).

Study the following statements regarding the preparation of herbarium sheets.


(i) The plant should be collected in the flowering stage.
(ii) Every detail regarding the plant such as locality, ecological conditions, vegetative and floral characters, etc. should be noted.
(iii) Plants are evenly pressed by unfolding all the plant parts between blotting papers (or newspapers) with the help of plant pressers.
(iv) Blotting papers need not be changed until the plant gets dried.
(v) After drying, the plant specimen is carefully mounted/pasted on the herbarium sheets.
(vi) The herbarium sheet is labeled on the lower right-hand corner representing the number of plant specimens, date of collection, etc.

  1. Name not published in Species Plantarum.

  2. Name proposed prior to 1961.

  3. Name which is not in Latin.

  4. Name for which holotype is not designated.

Show answer
Correct Option: D
Explanation:

Linnaeus described all plant species known to him in his book “Species Plantarum, 1753” in which he used the system of binomial nomenclature for first time. This makes option A incorrect as not all the plant species were described in this book. The scientific names of species are treated as in Latin regardless of their origin; this makes option C incorrect. According to principle of Priority, names published on or after May 1753 (the date of publication of The Species Plantarum) are considered valid; option B is incorrect. According to principle of typification, holotype is a specimen or illustration which is designated as representative of a species and is used for identification of new specimen. It is mandatory to mention the holotype during publication of new species on or after 1 January 1958; option D is correct. Thus, the correct answer is option D.

In a biological community, Gauze's principle explains.

  2. It is replaced by a vertebral column in adult frog.

  3. It is absent throughout life in humans from the very beginning.

  4. It is present throughout life in Amphioxus.

Show answer
Correct Option: C

Humans belong to the Phylum Chordate. Animals belonging to the Phylum Chordata possess a notochord either during early embryonic life or throughout the embryonic life. In some, it Is replaced by vertebral column. In humans, notochord is present only In the embryonic stage, it is replaced by vertebral column in the adult form.

zoology taxonomy and systematic botany nomenclature in classification nomenclature of animals introduction to plant kingdom binomial nomenclature nomenclature of organisms

  1. Inaccurate

  2. Cumbersome

  3. Not descriptive

  4. In Latin

Show answer
Correct Option: B
Explanation:

  • The term nomenclature means the scientific naming of organisms according to an established system. In earlier days common vernacular names were used which generally changes with change of language. Later in the haunt of one common internationally accepted name for a species, scientific names (Technical names) have been introduced in the form of polynomial, binomial and trinomial systems of nomenclature.
  • In the early seventeenth century, taxonomists started using a string of descriptive Latin words to designate a species. For example, in the herbal of Clusius (1583) a species of willow is named as Salix pumila angustifolia altera.
  • Polynomial nomenclature was discarded for the two main reasons that it was lengthy and difficult to remember, it often varies from place to place, scholar to scholar based on the characters chosen by them.
So the correct option is 'Cumbersome'.
