Food prepared by -----------is conducted to all parts of the plant by stem.

The stem transports water and dissolved minerals from the roots to the leaves, where they are used for photosynthesis and other processes. The stem acts as a pipeline, connecting the roots to the leaves and transporting the food manufactured by photosynthesis to all the parts of the plant. The food prepared by leaves is used by the plant to grow, produce flowers and fruits, and support its overall health. Hence, the stem conducts food to all parts of the plant, prepared by leaves.
