What part of a plant stores food?

Plants store food in the vertical shoot of their stems and roots. They also store water and other nutrients within their stems to be used at a later time.

The stem is the main stalk of a plant that not only stores food but also conducts it to other parts of the plant. The stem conducts water and minerals throughout the rest of the plant as well. Though plants produce their own food through photosynthesis, they also need to store food for winter when there is less sunlight. Different plants store different amounts in their stems and roots. Annuals tend to store less food, while biennials store more food because they require two growing seasons to complete a life cycle.
