Peng Min--Observation of Spruce

One of the significant features of spruce is their needle leaves. This is an adaptation for them to have a better fitness in the northern temperate and boreal climate in order to survive. Evergreen needle reducing the surface area prevents them from further water-loss by transpiration. By genetic analysis, genus Picea originated from North America.
Trees I observed share in common that they all have well-developed root system. This also helps them to gain more water and nutrients.
