Question

Lichens represent a mutualistic association between which two types of organisms?

RankGuru · Accepted Answer

1. **Symbiosis**: A lichen is a single life form that is a stable symbiotic association between a fungus and an algae/cyanobacteria.
2. **Partners**:
   - **Mycobiont**: The fungal component (usually Ascomycetes). It provides shelter and absorbs minerals/water for its partner.
   - **Phycobiont** (or Photobiont): The algal component ($e.g.,$ green algae or cyanobacteria). It prepares food through photosynthesis.
3. **Mutualism**: Both partners benefit from this close physical association, allowing them to live in harsh environments where neither could survive alone.
