An Léicean

Is comhpháirtíocht algaí-fungais é léicean agus tá ‘siombóis’ i gceist dá réir, a chiallaíonn dhá orgánach atá ag brath ar a chéile chun maireachtáil. Déanann an algaí bia a sholáthar agus déanann an fungas an t-uisce a ionsú. Fásann léicin éagsúla atá gorm, glas agus liath ar thulóga ar dhromchla an phortaigh.



Lichen


Lichen is an algae-fungus partnership, and is thus a ‘symbiosis’, meaning two organisms that need each other to survive. The algae provides food while the fungus absorbs water. Various blue, green and grey lichens grow on hummocks on the bog surface.
