Sphagnum erect, leafy, branched gametophyte with chlorophyllose cells and hyaline cells. This stage dominates the environment where "Sphagnum" grows, obliterating and burying the protonema and eventually building up into layers of dead moss called peat. Carpets of living "Sphagnum" may be attacked by various fungi, and one fungus that is also a mushroom, "Sphagnurus paluster", produces conspicuous dead patches. When this fungus and other agarics attack the protonema, "Sphagnum" is induced to produce nonphotosynthetic gemmae that can survive the fungal attack and months later germinate to produce new protonema and leafy gametophytes. It is unknown whether the leafy stage can produce
Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant Leningrad Nuclear Power Plant ( ()) is a nuclear power plant located in the town of Sosnovy Bor in Russia's Leningrad Oblast, on the southern shore of the Gulf of Finland, some to the west of the city centre of Saint Petersburg. It consists of four nuclear reactors of the RBMK-1000 type. These reactors are similar to reactors No. 1 and 2 of the Chernobyl Nuclear Power Plant. Two units of the VVER-1200 type are under construction at Power Plant II to replace the current RBMK reactors when they reach the end of their service lives.
