$\sf \pmb{Answer:-}$

➢ A lichen is a plant found on rocks or trees made of both a specific fungus and a specific algae that help one another. An example of a lichen is the colored patch growing on a tree branch.

➢Lichens have a body called a thallus, an outer, tightly packed fungal layer called a cortex, and an inner, loosely packed fungal layer called a medulla . Lichens use hyphal bundles called rhizines to attach to the substrate.

➢Lichens perform useful functions in nature. They provide shelter for other organisms. They also provide food for animals and materials that they can use to build their homes or nests. When lichens grow on rocks, the chemicals that they release contribute to the slow process of rock breakdown and soil formation.
