The system needed to be overhauled so that entire neighborhoods could be certified, not just buildings. Thatâs why NRDC teamed up with the Congress for the New Urbanism and the U.S. Green Building Council to launch LEED for Neighborhood Development, or LEED-ND, in 2010.
Young newly sprouted plants are called seedlings. They are what  grows directly after germination takes place. These plants then  grow into the adult plants.
As the spore germinates, it develops into a thin, filamentous stage called a protonema. As the protonema grows, it develops into a mature gametophyte with root-like rhizoids that anchor the plant and an erect, stem-like structure with whorls of leaf-like photosynthetic tissues.s the spore germinates, it develops into a thin, filamentous stage called a protonema.
