Although the leaves of camphor tree and holly are flat, they are covered with a layer of wax, which can not only keep warm, but also prevent water evaporation. 2

The leaves of deciduous trees are generally very thin, which is easy to evaporate water and needs more nutrition. In order to spend the cold winter, trees let their leaves die and fall, in order to lose less water and nutrition. So in winter, deciduous trees become bare. New branches and leaves will not grow until the next year when the weather is warm. 3
