n summer, plants do lots of photosynthesis, because they get lots of light and because it is warm. The food they make is sugar, which they use to grow new leaves, flowers, and seeds. In winter, things are less comfortable.The days get shorter, it gets colder and there is less sunshine. When it gets really cold, and freezes, their leaves can be damaged.
