Detailed explanation-1: -Roots suck up water and other nutrients from the soil.
Detailed explanation-2: -Plants take up essential elements from the soil through their roots and from the air through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
Detailed explanation-3: -Mineral nutrients come from the soil. These nutrients are absorbed by the plants roots when uptaking water. Mineral nutrients are broken up into macronutrients and micronutrients. The most important primary macronutrients for plants are nitrogen (N), phosphorus (P), and potassium (K).
Detailed explanation-4: -Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK.
Detailed explanation-5: -Root nutrient uptake and transport through the roots can occur by (i) diffusion, (ii) advection, and (iii) active uptake.
