Minerals are inorganic elements needed by the body for functions like building tissues, regulating fluids, and assisting in bodily processes. Major minerals like calcium, phosphorus, and potassium are required in amounts greater than 100mg daily, while trace minerals such as iron, iodine, and zinc are needed in lesser amounts.

The mechanism of uptake of mineral nutrients in plant cells can be of two types: active and passive. Passive uptake of nutrients is simple absorption along concentration gradients without any energy expense. Active uptake of minerals is required to transfer minerals from outside the cell to inside the cell utilising energy.
