Region covered by area codes 601 and 769. Area codes 601 and 769 are the telephone area codes for central Mississippi. The main area code, 601, was one of the original area codes implemented in 1947, and served all of Mississippi.n 1999, area code 662 was created in the northern half of Mississippi, including the Mississippi side of the Memphis area. The 1999 split was intended as a long-term solution, but within five years 601 was close to exhaustion due to the proliferation of cell phones, particularly in the Jackson area.
Lichen is the product of a symbiotic relationship between a fungus and a photosynthetic organism, usually a photosynthetic bacteria or algae.
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.he fungus benefits from the symbiotic relation because algae or cyanobacteria produce food by photosynthesis. The algae or cyanobacteria benefit by being protected from the environment by the filaments of the fungus, which also gather moisture and nutrients from the environment, and (usually) provide an anchor to it.
