Question

The central axis of the shoot system is called___ .

Answer 1

The central axis of the shoot system is called stem. It is the main body or stalk of a plant or shrub, typically rising above the ground.
The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.
