Which Part of the Sweet Potato Plant Absorbs Water & Mineral Salts from the Soil?

The Root System

  • Sweet potatos absorb water and nutrients from the soil via small, fibrous roots. They have a vining growth habit, sending roots into the soil in the places where ground contact occurs. These roots anchor the plant to the soil, as well as provide nutrients. Part of the root system grows through the soil and absorb nutrients directly from the earth, and other roots swell up to become storage roots. What is commonly called the sweet potato is actually the storage root -- the part of the plant that serves as a repository for stored sugars in the form of starches, as well as other nutrients gathered by the root system.
