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.
Cut across a dicot's stem, and the vascular bundles inside are arranged in concentric rings. The vast majority of trees are dicots, and tree rings are such concentric rings. When a dicot's seed sprouts, the seedling raises two leaves, or cotyledons, above the ground, with the future stem arising between them.This is very unlike the monocot's single cotyledon.About 170,000 dicot species are known worldwide.ut across a monocot's stem and the water-bearing tubes, or vascular bundles, inside are scattered throughout the pith, not arranged in concentric rings like the rings of a tree. When a monocot's seed sprouts, the first leaf up is a single spike looking like a simple blade of grass arising from the soil.
