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).
Only bacteria that can do photosynthesis can form lichens. They are called cyanobacteria. Lichens are made up of two organisms that mutually benefit each other (symbiosis).â¦ One organism is a fungus, which provides support and can extract nutrients from sources such as rocks.he other organism must be able to photosynthesize so that it can produce sugars for use by itself and the fungus. It is usually a green alga but can be a cyanobacterium, a bacterium that can produce food from sunlight (photosynthesis). Most lichens are composed of a fungus and a green alga.
