ACTIVE ABSORPTION OF MINERALS
sanaThe concentration of mineral solutes is much higher in the absorbing cells than outside in most cases. This increased concentration of minerals in the cells is called solute accumulation. Salt…
PASSIVE ABSORPTION OF MINERALS
The movement of minerals into the cell or tissue without the expenditure of energy is called passive absorption. This is a physical phenomenon. Passive absorption takes place by following ways:…
SOIL AS A SOURCE OF MINERALS
The soil consists of mineral and organic matter. The mineral matter consists of pebbles, sand and clay. The organic matter consists of dead and decomposed remains of plants and animals.…
