Botany - Mineral Nutrition Question with Solution | TestHub

All the mineral cannot be absorbed passively like water because minerals are present in the soil as charged particles which cannot be pass across the cell membrane and concentration of the mineral in the soil is usually lower than that of a root, hence mostly mineral is transported by active transport. But passive absorption of a mineral is also observed by facilitating diffusion, for e.g., potassium ions can be exchanged by hydrogen ions, absorbed to the surface of the cell membrane.
