Liches Organism

An isidium is more like a miniature lichen. The fungus also produces spores from an ara known as the apothecium. These spores are dispersed and germinate into bare-assed fungi, and not into bran-new lichens. New lichens are only produced when the fungus and the alga disperse unneurotic (Lichens, 2000).

Lichens hatful grow in almost any emplacement that is stable and has a reasonably well-lit surface. This includes on the soil, on jounces, and on the sides of trees. Lichens may absorb mineral nutrients from any of these substrates on which it grows, but is generally self-reliant in bunking itself through photosynthesis in the algal cells. This me

ns that lichens growing on trees are not parasitic since they do not feed on the trees. Lichens growing on rocks may release chemicals which swiftness the degradation of the rock into soil, and thus promote production of new soils.

They can grow in the harshest of conditions where few other organisms can survive, such as bare rock, desert sand, cleared soil, numb(p) wood, animal bones, rusty metal, and living bark (The Special Biology, 2000). virtually lichens grow very slowly: lots less than a millimeter a year. Because of this, they can be used to augur the dates of geological events such as the retreat of glaciers or the dates of rock slides.

Most lichens are temperate or arctic, though thither are many tropical and desert species (Lichens, 200). They seem to do better in drier environments where they are not oftentimes left in standing water. In bayous, lichens are often seen hangi
