Taxonomical Aids Questions in English

(B) $S$ Statement: Zoological parks are places where wild animals are kept in protected environments under human care,which enables us to learn about their food habits and behavior,thus aiding in wildlife conservation. This statement is true.
$R$ Reason: Botanical gardens are specialized gardens having collections of living plants for reference. While they are important for ex-situ conservation,the statement regarding the establishment of seed banks for gene pools is specifically associated with germplasm conservation centers or specialized botanical research facilities,not the primary definition of a botanical garden. However,in the context of biological taxonomy and biodiversity study,both are distinct ex-situ conservation strategies. Since $R$ describes a different type of conservation facility (germplasm/seed bank) rather than explaining why zoological parks are centers for wildlife conservation,$R$ is not the correct explanation for $S$. Both statements are factually correct in their respective domains.

(B) The Central National Herbarium is located in the Indian Botanic Garden,Howrah (Kolkata),not in Dehradun. Therefore,the pair $B$ is incorrect. The other pairs are correctly matched: The Museum of Natural History is in France,the British Museum of Royal Botanical Garden is in England,and the Herbarium of the Department of Botany at $M$.$S$. University is located in Vadodara.

(D) The correct answer is $D$.
$1$. The $National$ $Museum$ $of$ $India$ is located in $New$ $Delhi$,not in $Chennai$.
$2$. The $Bombay$ $Natural$ $History$ $Society$ $(BNHS)$ is located in $Mumbai$.
$3$. The $Zoological$ $Survey$ $of$ $India$ $(ZSI)$ has its regional center in $Jodhpur$.
$4$. The $Central$ $National$ $Herbarium$ is located in $Kolkata$ (at the $Indian$ $Botanic$ $Garden$).

(A) botanical garden contains living plants for reference,study,and conservation,whereas a herbarium is a storehouse of collected plant specimens that are dried,pressed,and preserved on sheets.
Therefore,the primary difference lies in the nature of the plant collection (living vs. dead/preserved).

(C) The $Muséum \text{ } national \text{ } d'histoire \text{ } naturelle$ (National Museum of Natural History) is located in Paris, France.
The Royal Botanic Gardens, Kew, is a world-famous botanical garden located in Kew, London, United Kingdom.
Therefore, the correct sequence is Museum of Natural History (Paris) and Royal Botanical Garden (Kew).

(D) Botanical gardens are specialized gardens having collections 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. Thus,Statement $P$ is true.
Zoological parks are places where wild animals are kept in protected environments under human care and which enable us to learn about their food habits and behavior. They also play a crucial role in the conservation,rehabilitation,and care of rescued or endangered animals. Thus,Statement $Q$ is true.
Therefore,both statements are correct.

(D) In the context of botanical gardens and their roles,the options are evaluated as follows:
$A$. Conservation is achieved through tissue culture techniques.
$B$. Botanical gardens provide aesthetic appeal,and large trees like the Banyan tree are often featured.
$C$. Germplasm banks are used to store genetic material (genes).
$D$. 'Phlodhan' is not a standard term associated with public service in the context of botanical gardens or taxonomy. Therefore,this pair is incorrectly matched.

(A) The correct matches are as follows:
$1$. $(a)$ Central National Herbarium is located in $(iii)$ Kolkata.
$2$. $(b)$ Lloyd Botanical Garden is located in $(iv)$ Darjeeling.
$3$. $(c)$ Safari Park is represented by $(i)$ Sasan Gir (a well-known wildlife sanctuary/safari area).
$4$. $(d)$ Ethno Gallery is a type of $(ii)$ Museum.
Therefore,the correct sequence is $(a-iii), (b-iv), (c-i), (d-ii)$.

(B) The preparation of a herbarium involves several sequential steps:
$1$. Collection of plant specimens.
$2$. Drying (to remove moisture).
$3$. Poisoning (to prevent fungal or insect attack).
$4$. Mounting (fixing the dried specimen onto a herbarium sheet).
$5$. Labeling (providing information about the specimen).
Since the question asks for the step performed after drying,and poisoning is typically done before or during the drying process,the next logical step in the preparation sequence is mounting the specimen onto the herbarium sheet.

(B) In the process of preparing a herbarium,plant specimens are collected and then dried to remove moisture.
This is done by placing the plant specimens between sheets of blotting paper (or newspaper) and applying pressure using a plant press.
This method ensures that the plant dries flat and retains its shape without decaying.

(C) हर्बेरियम तैयार करने की विधि में,'माउंटिंग' (Mounting) का अर्थ है सूखे हुए पादप नमूने को हर्बेरियम शीट पर व्यवस्थित रूप से रखकर उसे धागे के टांके (Stitching) या चिपकने वाली पट्टियों (Adhesive strips) की सहायता से स्थायी रूप से चिपकाना। यह प्रक्रिया नमूने को सुरक्षित रखने और अध्ययन के लिए व्यवस्थित बनाए रखने हेतु की जाती है।

(C) herbarium is a storehouse of collected plant specimens that are dried,pressed,and preserved on sheets.
These sheets are arranged according to a universally accepted system of classification.
Further,these specimens,along with their descriptions on herbarium sheets,become a storehouse or repository for future use.
The herbarium sheet also carries a label providing information about the date and place of collection,English,local and botanical names,family,and the collector's name.
Typically,the dried plant specimen is mounted on the herbarium sheet,and the label is placed on the lower right-hand corner.
However,the question asks what is attached to the sheet; the primary component attached is the dried plant specimen itself.

(B) The correct sequence for preparing a herbarium specimen is as follows:
$1$. $T$: Collection of plant specimens.
$2$. $U$: Pressing (to flatten the specimens).
$3$. $Q$: Drying (to remove moisture).
$4$. $S$: Poisoning (to prevent fungal or insect attack using chemicals like mercuric chloride).
$5$. $P$: Mounting (fixing the specimen on a herbarium sheet).
$6$. $R$: Labeling (providing details like date,place,scientific name,collector's name,etc.).
Thus,the correct order is $T-U-Q-S-P-R$.
