Active transport

The video tutorial explains how particles typically move down a concentration gradient, from high to low concentration. It introduces active transport, a process that moves particles against this gradient, from low to high concentration, using energy and specialized carrier molecules. The tutorial highlights how plants utilize active transport to absorb nutrients from the soil, specifically through root hair cells.
