Question

what is lichen. explain with an example.

Answer 1

There once was a little patch of fungi that took a lichen (pronounced liken) to a beautiful batch of algae. This terrible joke has helped me remember what two organisms make up lichen. While you're probably not rolling on the floor laughing, hopefully it'll help you remember, too. Lichen, if you haven't gathered already, is formed by the mutualistic relationship between a fungus and an alga. Mutualism is a type of relationship where both organisms benefit from being together. So, the algae help the fungi and the fungi help the algae. Before we go on, something to note (in case you're asking yourself what in the world an alga is):

Answer 2

Lichen is a very good example of dual organism
*it is a symbiotic association ie, mutually useful association betwn Algae and Fungi
*Algae prepare food for fungi( from CO2 and H2O)
*Fungi provide protection, anchorage and absorb mineral and nutrients for algae

*Algal component is called -Phycobiont
*Fungal component is called-Mycobiont
Hope this information wil help you
