Lichens are traditionally defined as a symbiotic relationship between fungi and algae and/or cyanobacteria. This union forms a unique structure called the thallus, which attaches to surfaces such as rocks and tree bark. Recent reports challenge the view that lichens are comprised of one fungus and...
The fungus can obtain photosynthates from the algae or cyanobacterium and the algae or cyanobacterium can grow in a drier environment than it could otherwise tolerate. However, most scientists consider this symbiotic relationship to be a controlled parasitism (a relationship in which one organism ...
An organism that consists of a fungus and an alga living together in a symbiotic relationship. The alga supplies nutrients by photosynthesis, while the fungus shades the alga from excessive sunlight and supplies water by absorbing water vapor from the air. Lichens often live on rocks and tree ba...
2. It can be inferred from paragraph 2 that the fungi in lichens benefit from their symbiotic relationship with algae in what way? A.The algae help the fungi meet some of their energy needs. B.The algae protect the fungi from the Sun's radiation. C.The algae provide the fungi with ...
algae for food and in return provide a shady, moist, vitamin-rich environment, so sci- entists classify lichens based on their associated fungal species. Whether the fungi were harvesting algae or cyanobacteria, the symbiotic modus operandi of the lichens proved to be the same. Perhaps Trevor ...

each one is a symbiotic combination of an alga and a fungus.The algae capture the sun's energy by photosynthesis and store it in organic molecules.The fungi absorb moisture and mineral salts from the rocks, passing these on in waste products that nourish algae.It is significant that the earl...
The new study, which was published online today in the journalMolecular Ecology, finds that fungalorganismsreduce their core genomic makeup while coalescing with algae to form alichenpartnership, one presumed to be "obligate" (i.e., requiring both partners) but had previously lacked direct genetic...
Nelsen didn’t set out to disrupt lichen’s status as some of the land’s first colonizers. He was initially interested in finding out how the algae-fungus relationship that makes up lichens came to be. If lichens could update their relationship status on Facebook, it would definit...
