Vedclass · Answer

(A) $Colchicine$ is an alkaloid obtained from the corm of $Colchicum 	ext{ } autumnale$.It belongs to the family $Liliaceae$ (Lily family), not the $Fabaceae$ family.$Colchicine$ acts as a spindle poison; it inhibits the formation of spindle fibers during cell division, thereby preventing cytokinesis.By inhibiting cytokinesis, it leads to the doubling of chromosomes, a process known as inducing polyploidy.Statement $V$ represents the floral formula of the $Liliaceae$ family, which is $\oplus 	ext{ } 	ext{O} 	ext{ } P_{3+3} A_{3+3} G_{(3)}$.Therefore, statements $I, II, III,$ and $V$ are correct.

Column-$I$ (Local Name)	Column-$II$ (Scientific Name)
$A$. China rose	$i$. Bougainvillea spectabilis
$B$. Lemon	$ii$. Allium cepa
$C$. Sunflower	$iii$. Hibiscus rosa-sinensis
$D$. Onion	$iv$. Citrus limon
$E$. Bougainvillea	$v$. Helianthus annuus
-	$vi$. Rosa indica

Colchicine:
$I.$ is obtained from $Colchicum \text{ } autumnale$
$II.$ is a cytokinesis inhibitor
$III.$ induces polyploidy
$IV.$ is obtained from $Fabaceae$ family
$V.$ Floral formula: $\oplus \text{ } \text{O} \text{ } P_{3+3} A_{3+3} G_{(3)}$
Which are the correct statements?
