The biblical legend says that when Mosesled his people through the desert, and all the food was eaten, the exhausted people were ready to die of hunger. But suddenly the wind rose, and gray lumps fell on the hot sand, which the hungry people ate raw and from which they cooked porridge. And they thought that it was God who sent them the manna of heaven.
Structure of lichen
On Earth, lichens appeared a hundred million years agoback. For a long time scientists could not determine whether this is a mushroom or algae. Until they came to the conclusion that lichen is a symbiosis of the fungus and algae. In its structure the reindeer moss resembles a tree in miniature: there is a "trunk" - a thallus, in all directions from which "branches" diverge - an interlacing of the fungus hypha and alga cells that protect the lichen from damage and drying out. There are some "roots" - rhizoids, through which lichens attach themselves to stones and soil. The anatomical structure of lichens is:
Reproduction and growth
Lichens can reproduce by spores, whichproduces a fungus, or vegetatively: slices of thallus. Are able to grow in the most severe conditions: in rocks, on stones, on poor soils, in sand. They are the first to develop unsuitable places for life and create conditions for other organisms. They grow very slowly: about 5 mm per year. The color range is varied: from black, white, gray, to bright yellow, orange and red. Until now, the mechanism for producing lichen color has not been clarified, it is obvious that it is associated with exposure to sunlight. At the slightest contamination of the atmosphere lichens perish, because, unlike plants, they do not have a protective cuticle, and poisonous substances penetrate through their entire surface.
