Answers
Answer:
1.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.
2.The potatoes grow on underground stem. The potato tubers are actually thickened stem they have buds that sprout stem and leafs. ... And the potatoes are under the ground so they are called underground stem.

3.It is the component that transports water and mineral from the root to many other areas of the tree and prepares food from leaves. Stems are one of the plant storerooms where the prepared food is processed in starch form. Few stems help to replicate by vegetative propagation and also help to grow flowers and fruit.
4.Underground stems are modified plants that derive from stem tissue but exist under the soil surface. ... ... Examples of underground stems include corms, such as taro (left); rhizomes, such as ginger (center); and tubers, such as potatoes (right).
6.The stem of a plant can be compared to two-way traffic because, in the stem there are two types of tubes, one that carries water and minerals from roots to the leaves and other parts and the other that carry food from leaves to other parts of plant and roots.
