Answer:

1. Lichens occur in certain specific habitats that are least polluted. They grow on rocks, leaves, the bark of trees and forest floor.

2. Lichen can be called a compound plant because an alga and a fungus live together in its thallus in mutual partnership and each gets to benefit from one another.

3. Fungus provides shelter to the alga and maintains humidity inside the thallus of lichen. Moisture is generally absorbed from the atmosphere. Algae manufacture the starch, which is used as food by the fungus.

4. Lichen thallus may be flat, leaf-like or branched and larger in size.

and are classified as Crustose lichen, Foliose lichen and fruticose lichen respectively
