Lichens are complex organisms that consist of two components: an alga and a fungus.
These two components are in a symbiotic or mutualistic relationship with each other.
Mycobiont is a fungal component of lichen that protects algae and absorbs minerals and water.
Phycobiont is the algal component of lichens that prepares food for fungi.
Functions of Mycobiont:
In lichen, the one partner is a fungus which is known as the mycobiont which is heterotrophic.
Mycobiont plays a major role in providing water, nutrients, and shelter to the algal partner.
The other component i.e., algae is known as the phycobiont which is autotrophic and is responsible for providing nutrition and making organic food by photosynthesis..
