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).
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. Some live in a mutually beneficial symbiotic relationship with another organism, often a plant. 2  The association of fungus and plant root is called a mycorrhiza. 3  Some 80% of land plants benefit from symbiotic mycorrhiza. 4  The plant benefits by more-efficient mineral (especially phosphorus) uptake.
