You may identify a tree from its leaves by comparing its different attributes to listings in a database or guide of tree leaves. Tools needed to identify a leaf include a compilation of known tree attributes, which can be found online, in books or through different applications.
Trees need leaves primarily because of photosynthesis and respiration. Photosynthesis is the process by which carbon dioxide is converted into nutrients that are needed by plants for survival.
Professional forester and natural resource consultant Steve Nix describes scale-like leaves, needles and typical leaves with a leaf stalk, veins and a midrib in discussing how these leaves play a part in identifying trees. Nix explains that typical leaves usually come from hardwood and deciduous tre

As of 2015, apps that help identify tree leaves, include Leafsnap and the Virginia Tech Tree ID, also called vTree. These apps help identify leaves and trees using photo comparisons.
To identify oak trees using leaves, examine the leaf branching on the corresponding tree, determine if the leaf is simple or compound, and look for lobes on the leaf's edge. Also, check to see whether the lobes are pointed or rounded, observe the sinus depth, and look for leaves that are shaped oddl
