Vedclass · Answer

(A) In $Agaricus$ (a member of Basidiomycetes),the primary mycelium is monokaryotic and haploid,which is formed by the germination of basidiospores.When two compatible primary mycelia fuse through a process called somatogamy (plasmogamy),they form a secondary mycelium.This secondary mycelium is dikaryotic (binucleated),meaning each cell contains two nuclei of different mating types.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the formation of the binucleated secondary mycelium.

$A$: Secondary mycelium of $Agaricus$ is binucleated.
$R$: Secondary mycelium is formed by somatogamy of primary mycelium.
