Question
How do lichens exhibit symbiosis?
✓
Answer
- Lichens are composite organisms showing symbiosis between an alga and a fungus.
- The algal component (phycobiont) is autotrophic and prepares food for the fungus too.
- The fungal component (mycobiont) is heterotropic and absorbs water and mineral nutrients for the alga and also provides protection to the alga.
- Thus, both the alga and fungus are mutually benefitted.
