The process that carries the "food" manufactured in the leaf to other parts of the tree is called phloem transport. The phloem is a type of plant tissue that contains specialized cells called sieve tubes and companion cells. These cells work together to transport sugars, amino acids, and other nutrients from the source (usually the leaves) to the sink (other parts of the plant such as the roots, stems, and flowers) through a process called translocation. This process is essential for plant growth and development and is one of the key functions of the vascular system in plants.
