Vedclass · Answer

(B) Active transport occurs in roots due to two main factors:$(i)$ Minerals in the soil are present as charged particles (ions),which cannot pass through the cell membrane via passive diffusion.$(ii)$ The concentration of minerals in the soil is usually lower than the concentration of minerals in the root cells.Therefore,most minerals must enter the cytoplasm of epidermal cells of the roots through active transport,which requires energy in the form of $ATP$.
