Describe the symbiotic relationship that enables a lichen to exist?

Answer 1

Okay. Firstable, there are 3 kinds of symbiosis : parasitism, mutualism and commensalism. If u want to understand it ezly. Paratism=one of them good others are super-bad. e.g.)tapeworms, lampreys whatever... mutualism=both of them happy e.g.)alga+fungus&linchens, birds commensalism=one of them is happy others not happy not sad (so so) the answer 4 ur Q is The association of an alga and a fungus in linchens is another example of mutualism. the nonphotosynthetic fungus provides moisture and support for the alga, which in turn synthesizes food for the fungus and itself. did u like it? i hope u did.

Answer 2

A lichen is a symbiosis between a fungus and a photosynthetic partner such as a green alga, a cyanobacterium, or both. The fungus absorbs minerals and other nutrients from rocks or logs and retains water that the photosynthetic partner needs for photosynthesis. Through photosynthesis, the alga produces carbohydrates that the fungus uses for food.

Answer 3

The lichen is a symbiosis between two different species: (1) a host fungus (i.e. mycobiont) and (2) endosymbiotic algae or cyanobacteria (photobiont). The host fungus provides the algae with protection from dessication, while the algae/cyanobacteria provides the host with carbohydrates produced from photosynthesis. The relationship is mutually beneficial (i.e. symbiotic), as both parties stand to gain from the association.

Answer 4

lichen is called a symbiont because symbionts are the organisms live together and help each other for their survival. In lichen, the two organisms are fungus and algae.
