&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[Image:Lichen.jpg|thumb|right|px|Lichen]]'''Lichen''' are [[symbiosis|symbiotic]] organisms containing both [[algae]] and [[fungi]]. The fungal cells provide structure and shelter for the algae. The algae, in turn, provide energy to the fungi through photosynthesis.&lt;br /&gt;
&lt;br /&gt;
==Survivability==&lt;br /&gt;
Lichens can survive in some of the most barren and severe regions of the world. They tolerate extreme cold and dry conditions through dormancy and the ability to recover quickly when conditions are favorable. Although lichens can grow in regions with more rainfall, they actually require little rainfall to survive.&amp;lt;ref&amp;gt;http://earthobservatory.nasa.gov/Experiments/Biome/seedlichen.php&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The [[ESA]] launched lichen samples into Earth [[orbit]], where they were exposed to the full [[vacuum]] of space for 14.6 days. Despite the intense [[radiation]] and vacuum, the samples returned alive and unharmed.&amp;lt;ref&amp;gt;http://www.esa.int/esaCP/SEMUJM638FE_index_0.html&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Though it is unlikely that lichen can grow on the current [[surface composition|surface]] of Mars, they will be some of the first organisms able to colonize durring [[terraforming]].&lt;br /&gt;
&lt;br /&gt;
==Use==&lt;br /&gt;
Lichen is an important food source for reindeer and some species of [[moth]]. [[Rock tripe]] is a species of that is eaten by humans, and is used in the cuisine of Korea. Chemicals produced by certain species are useful in [[medicine]] and industry.&lt;br /&gt;
