Answer 1

Rhizome is a type of underground stem, these are modified plant structures derived from stem tissues but they exists under the soil surface. In Plants, seedlings shows two axes of growth, structures that developed downward called as roots and those developed upward out of the soil called stems. In ginger plant development is upward out of the soil and hence, the stems are modified to store energy, these stems have nodes with buds where leaves and flowers arise at specific location . Rhizome usually produce aerial stem and underground roots from these buds. So, it looks like and acts like a root but is different because it grows horizontally.
