What does the roots and the stem do differently?

Stem

1. Grows upward show negative gravitrotropism

2. Stems don't absorb water and nutrients

3.Stems have trichomes

Roots

1 show positive gravitrotropism

2 absorb water and Minerals

3 bears root hairs

Roots are the underground part of the plant, and the main function is the absorption of water and minerals from the soil, conduction, storage of reserve foods and mainly in the anchorage of the plant. The chief distinction from the stems is the lacking of buds and leaf scars, but have root cap and branches that originate from internal tissues than from buds. And Stems are the part of the plant, that possesses buds, leaves and roots at its basal ends. The primary function of the stem supports the leaves and to transport minerals and water to the leaves, where it proceeded to convert into useful products by the process of photosynthesis, and then further these are transported to other parts of the plants including roots.
