Sugar is moved to all the plant cells of a plant, with the cells of the underground roots. The plants dont use all of the sugar they make immediately, they will use some of it and store some of it for use in the winter when the food sources are hard to recive. For long-term storage, the plants will join the sugars with a chemical called starch. Plants arent the olny living organisms that get starch. We get it too! When we eat food from plants, you eat the sugars and starches from that plant. Some plants that contain starches are potatoes, rice, corn, pastas, fruits, bean, grain, vegetables, and all bread products do contain starch as well. We convort starches from plants into fuel to run us for the day also known as starch ...
