Vedclass · Answer

(A) Lichens represent a symbiotic relationship between algae (phycobiont) and fungi (mycobiont). In this association,the algal component provides food through photosynthesis,while the fungal component (mycobiont) provides protection,anchorage,and absorbs water and minerals. Since fungi are heterotrophic organisms,they cannot synthesize their own food,which is why they rely on the algal partner. Therefore,both Assertion $A$ and Reason $R$ are true,and $R$ correctly explains why this symbiotic relationship exists.

Assertion $A$: Lichens are symbiotic associations between algal and fungal components. Reason $R$: The mycobiont components of fungi are heterotrophic. Which option is correct for Assertion $A$ and Reason $R$?
