Plants use inorganic minerals for nutrition, Complex interactions involving weathering of rock minerals, decaying of organic matter, animals, and microbes take place to form inorganic minerals in soil. Plant roots absorb mineral nutrients as ions in soil and are called Mineral ions.
Mineral ions that are required in large amounts are called macronutrients and those that are required in small amounts are called micronutrients. Today we will be looking at 3 macronutrients absorbed by the plant as Nitrate, Phosphate and Potassium ions
Nitrate ions promote stem and leaf growth
Phosphate ions are critical for mitosis and cell division
Potassium ions control cell turgor and operation of stomata
All three of these ions have many functions other than the ones on the sheet and I will talk more about those
Nitrate ions are one of the major components of proteins, nucleic acids, vitamins and hormones, coenzymes, and nucleotides. Nitrogen promotes rapid growth, increases leaf size and quality, and promotes fruit and seed development.
Phosphate ions are a component of cell membranes, certain proteins, all nucleic acids and nucleotides, it is involved in energy transfer such as ATP and ADP. It activates
