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).
It is often thought that lichens are a fungus or disease that is damaging the plant but in reality that is not the case. Lichens are unique organisms. It is a fungus and algae combined to live together. Although lichens really do not look like a fungus or algae both work together so that lichens can survive.
