Nutrient transport refers to the process by which essential substances, such as vitamins, minerals, and carbohydrates, move from one part of an organism to another. In humans, this occurs primarily through the bloodstream, where nutrients absorbed from food in the digestive system are carried to cells throughout the body. In plants, nutrient transport happens through specialized tissues called xylem and phloem. The xylem transports water and minerals from the roots to the leaves, while the phloem distributes sugars produced during photosynthesis to various parts of the plant, ensuring all cells receive the nutrients they need to function properly.
