Taxonomical Aids Questions in English

(A) The process of preparing a herbarium specimen involves several systematic steps:
$1$. Collection: Gathering the plant material from the field.
$2$. Pressing: Placing the specimen between sheets of paper to flatten it.
$3$. Drying: Removing moisture from the specimen,often by changing the drying sheets periodically.
$4$. Mounting: Attaching the dried specimen onto a standard herbarium sheet.
$5$. Preservation: Treating the specimen with chemicals (like mercuric chloride) to prevent fungal or insect attacks and storing it in a herbarium cabinet.

(C) 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. These are commonly known as $Zoo$s.

(B) taxonomic key is a tool used for the identification of organisms based on their similarities and dissimilarities.
Each statement in a taxonomic key is known as a $Lead$.
When two contrasting statements are presented together,the pair is called a $Couplet$.

(A) taxonomic key is a device used for the identification of organisms based on their similarities and dissimilarities.
Keys are based on the contrasting characters generally in a pair called a couplet.
Each statement in the key is called a lead.
Taxonomic keys are analytical in nature,not synthetic.
Therefore,the statement 'Taxonomic keys are generally analytical in nature' is correct,but the option stating they are 'synthetic' is incorrect.
Since the question asks for the incorrect statement,option $A$ is the correct choice because it falsely claims they are synthetic.

(D) herbarium sheet is a dried and pressed plant specimen mounted on a sheet of paper,used for taxonomic studies.
It typically includes information such as the date and place of collection,English,local,and botanical names,family,and the name of the collector.
However,the height and color of the plant are not recorded on the herbarium sheet because the plant specimen is dried and pressed,which causes it to lose its original color and height dimensions.

(A) The stuffing method is a technique used in museums to preserve larger animals,specifically $Birds$ and $Mammals$.
In this process,the internal organs are removed,and the skin is filled with materials like cotton or straw to maintain the original shape and appearance of the organism.
Plants are typically preserved using herbarium sheets (pressing and drying),and insects are preserved in insect boxes after killing and pinning.
Therefore,the correct option is $A$.

(C) The taxonomical aid 'key' is used for identification of plants and animals based on the similarities and dissimilarities. Statement $(a)$ is true.
Key is analytical in nature because it involves the analysis of characters to identify an organism. Statement $(b)$ is true.
Keys are based on the contrasting characters generally in a pair called couplet. Statement $(c)$ is true.
Separate taxonomic keys are required for each taxonomic category such as family,genus,and species for identification purposes. Therefore,the same key cannot be used for all categories. Statement $(d)$ is false.
Each statement in the key is called a lead. Statement $(e)$ is true.
Thus,statements $(a), (b), (c),$ and $(e)$ are correct.
