Vedclass · Answer

(D) In lichens,the fungal component is known as the mycobiont,and the algal component is known as the phycobiont.The mycobiont is the dominant partner because it provides the structural framework,protection,and absorbs minerals and water for the lichen.Therefore,the assertion that the phycobiont is the dominant parent is incorrect.Regarding the reason,the algal component (phycobiont) can be either a prokaryote (like $Cyanobacteria$) or a eukaryote (like green algae).Thus,the statement that the algal component can be eukaryotic only is also incorrect.Since both the assertion and the reason are false,the correct option is $D$.

$A$: Phycobiont is the dominant parent in lichens.
$R$: The algal component in these dual organisms can be eukaryotic only.
