What phenomena can be observed in plants in winter? What changes in plants in winter?

Most plants are dormant in winter. All life processes are either very slow or stopped. Herbaceous plants mainly survive on the basis of the root system, and in the spring they put out a new stem. Some grasses remain green under the snow. Those plants that do not shed their leaves in winter have certain adaptations to the cold. In their cells there are peculiar substances that work just like antifreeze in a car. If the cells begin to freeze, they will collapse and the plant will die.
