In lichens, fungi and algae live in a symbiotic relationship where the fungi provide shelter and minerals, while the algae perform photosynthesis and provide food.

Symbiotic Relationship between Fungi and Algae in Lichens
Fungi and algae have a symbiotic relationship in lichens, where they live together in a mutually beneficial partnership. This relationship is essential for the survival and growth of lichens.

Mutualism
The relationship between fungi and algae in lichens is a form of mutualism, where both organisms benefit from each other. The fungi provide a protective structure for the algae to grow within, while the algae provide essential nutrients through photosynthesis. This mutual exchange of resources allows both organisms to thrive in various habitats.

Structure of Lichens
Lichens are made up of a fungal partner (mycobiont) and an algal partner (photobiont) living together in a symbiotic association. The fungal partner provides a protective environment and absorbs water and nutrients from the surrounding environment. The algal partner, on the other hand, produces food through photosynthesis using sunlight.

Benefits of Symbiosis
The symbiotic relationship between fungi and algae in lichens allows them to colonize harsh environments where neither organism could survive alone. Lichens can grow on rocks, trees, and even in extreme climates like deserts and tundras. This partnership enhances the adaptability and resilience of lichens in diverse ecosystems.

Conclusion
In conclusion, the relationship between fungi and algae in lichens is a prime example of symbiosis in nature. This partnership allows both organisms to thrive in challenging environments by working together and benefiting from each other's strengths.
