Plant Roots: The root system of a plant constantly provides the stems and leaves with water and dissolved minerals. In order to accomplish this the roots must grow into new regions of the soil. The growth and metabolism of the plant root system is supported by the process of photosynthesis occurring in the leaves. Photosynthate from the leaves is transported via the phloem to the root system. Root structure aids in this process.
The stem is the major aerial support system in most plants. Sometimes called a stalk or trunk, it holds up the plant into the air and provides a pathway for fluid transport between the shoot and the root. The stem also may represent a huge volume for storage of materials.
