Detailed explanation-1: -Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients. Vascular tissue (vascular cylinder) is the the piping that helps conduct water and nutrients upward to the shoots. The epidermis forms the protective skin of the roots.

Detailed explanation-2: -► Roots anchor the plants in the soil and absorb nutrients and water that are needed by the rest of the plant. ► Stems support the upper part of the plant and act as a transport system for nutrients, water, sugar, and starches.
