“Active Transport”“The movement of particle from an area

of lower concentration to an area of higher concentration by using energy.”

This includes the absorption of: Dissolved mineral salts by the root hairs, Glucose and amino acids by cells in the

small intestine of humans by villiFig. 2.4 Active transport-molecules diffuse against the concentration gradient from B to A.
