      Not all plants shed their leaves during winter but those that do so is because their leaves are not protected by anti-freeze chemical that protect the leaves.

      Trees lose their leaves in winter because the ground in cold climates can freeze making the soil as dry as desert. To reduce moisture loss due to transpiration through the plants leaves, the tree simply drops them until the warmer spring weather returns.
