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. 1  Lichens are fungi that live in a symbiotic association with an autotrophic green alga or cyanobacterium (the photobiont) or â in some cases â both. 2  The fungal partner (the mycobiont) in most lichens (98% of them) is an ascomycete. Zygomycetes make up the remainder.
