There are different types of plant that survive in winter and that not like the one that doesn't survive are ANNUALs: these are the plants that produce a handsome amount of seeds during spring season. But they don't survive in winter. But in the spring season, new plants grow from the seeds.Second one is PERENNIALSThese are plants that survive during the winter season. Usually the plant part that breeds above the ground expires, but the roots are protected by snow layers.Then in the season of spring, this plant will start to grow once again.All plants find ways to survive the winter. The reason why plants lose their leaves are1- In the winter, heat becomes less available.2- In the winter, light become less available.3- In the winter, Water becomes less available.4- In the winter, minerals become less available.5- The plants then began to get rid of the leaves by discontinuing the flow of food to these expire leaves.And once the supply of the food from plant to leaves is close off, these leaves began to change their colour and with the passage of time they beginning to fall off.
Plants need to lose leaves in the fall because the leaves are very dry. In the winter, plants already have all their leaves lost in the fall, but they can't grow back because it is too cold. In the spring, it gets warmer so leaves can grow back. In the summer, a few leaves die because they are too hot and too dry.

By definition, a deciduous tree looses its leaves for winter - well - usually.Deciduous means "falling off at maturity" or "tending to fall off". Deciduous plants, including trees, shrubs and herbaceous perennials, are those that lose all of their leaves for part of the year. In some cases leaf loss coincides with winter - namely in temperate or polar climates. While in other areas of the world, including tropical, subtropical and arid regions of the world, plants lose their leaves during the dry season or during other seasons depending on variations in rainfall.
