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.

Fruit Type	Plant Species
$(a)$ Siliqua	$(i)$ Lycopersicum esculentum
$(b)$ Caryopsis	$(ii)$ Triticum aestivum
$(c)$ Berry	$(iii)$ Helianthus annuus
$(d)$ Cypsela	$(iv)$ Brassica campestris

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?
