CBSE Class 10 Answered
When the roots of a tree take up minerals from soil, is that active or passive transport?
Asked by Gulmarg | 14 Jun, 2009, 03:03: PM
Expert Answer
Mineral ions are absorbed by root hair cells by active transport, which needs energy. This is because mineral ions move against their concentration gradient from lower solute concentration in the soil to higher solute concentration in the root hair cells. The root hair cell is equipped with a high number of mitochondria, which are needed for aerobic respiration that produces energy for active transport. The cell membrane of these root hair cells has protein channels for the process of active transport .
