What is a lichen composed of?

-✅Explanation: Lichens are symbiotic associations between a fungus and an alga or cyanobacterium. The fungus provides a protective structure and absorbs water and minerals, while the alga or cyanobacterium photosynthesizes and provides organic nutrients for the lichen.

🔑Key Points:
-Lichen
-It is a symbiotic relationship between algae and fungi.
-The fungus provides a stable surface for the algae to grow on.
-The algae produce food for both partners through photosynthesis.
-This mutualistic relationship allows lichen to survive in harsh environments, such as rock surfaces and tree bark.
-The fungal component of lichen is responsible for
-retaining moisture and
-protecting the algae from harmful UV rays.
-The algae component provides the energy needed for
-growth and
-reproduction
-This unique symbiosis relationship between algae and fungus sets lichen apart from other forms of plant life.
