How do you change your computer screen from landscape to portrait setting? My son was playing with the computer and when I looked at the screen he somehow changed it to a landscape appearance rather than standard portrait.
Lichens have been described as dual organisms because they are symbiotic associations between two (or sometimes more) entirely different types of microorganism 1  -. a fungus (termed the mycobiont). 2  a green alga or a cyanobacterium (termed the photobiont).
Lichens are bizarre organisms and no two are alike. Lichens are a complex life form that is a symbiotic partnership of two separate organisms, a fungus and an alga. The dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.
