How do lichens multiply?

Answer 1

A lichen-forming fungus controls the process of association with its algae (that combine with fungi to form lichens) . This association is basically parasitic (the algae are to some extent transformed and even killed by the fungus (form a kingdom distinct from "true plants" in that they lack chlorophyll and thus must find food as animals do, accomplishing this either by living on dead organic materials or on living organisms as parasites) , which absorbs carbohydrates produced by the algae's photosynthesis), but the fungus also protects the algae from excess light, spreads their surface area, and provides a steadied supply of water without which the algae would die, so "symbiosis" is the typical, stabilized form of their association.

Answer 2

Lichens are found almost everywhere , these are most common in damp places such as rainforests and temperate forests, and places where there is little or no sunlight. They can commonly be found on the ground or growing on surfaces such as bark of trees but are not restricted to them.

Answer 4

Lichens can reproduce through both sexual and asexual means. Asexual reproduction occurs through fragmentation or the dispersal of small pieces of lichen to establish new colonies. Sexual reproduction involves the production of spores that can germinate to form new lichen thalli.
