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).
The lichen combination of fungus with algae and/or cyanobacteria has a very different form (morphology), physiology, and biochemistry to the component parts growing by themselves.ichens are said to be species, but what is meant by species is different from what is meant for plants, animals, and fungi, for which species implies a common ancestral lineage. Lichens are really combinations of species from two or three different biological kingdoms, so there is no common lineage.
