The practical purpose of taxonomy or classification is .........

Define a taxon. What is meant by taxonomic hierarchy? Give a flow diagram from the lowest to highest category for a plant and an animal. What happens to the number of individuals and the number of shared characters as we go up the taxonomic hierarchy?

Match the following columns correctly:

Column $I$ (Organism)	Column $II$ (Family)	Column $III$ (Order)
$i$. Sunflower	$a$. Blattidae	$p$. Opisthopora
$ii$. Earthworm	$b$. Asteraceae	$q$. Glumiflorae
	$c$. Megascolecidae	$r$. Anura
		$s$. Asterales

Identify the correct sequence of taxonomic categories.

Match column $I$ with column $II$ and choose the correct option.

Column-$I$	Column-$II$
$A$. Family	$V$. Solanaceae
$B$. Kingdom	$IV$. Plantae
$C$. Order	$II$. Polymoniales
$D$. Species	$I$. tuberosum
$E$. Genus	$III$. Solanum

Select the correct match for Column $X$ and Column $Y$:

Column $X$ (Organism)	Column $Y$ (Family)	Column $Z$ (Order)
$(1)$ Sunflower	$(A)$ Blattidae	$(P)$ Opisthopora
$(2)$ Earthworm	$(B)$ Asteraceae	$(Q)$ Glumiflorae
	$(C)$ Megascolecidae	$(R)$ Anura
		$(S)$ Asterales
