Mineral ions are charged particles that are important for the healthy growth and function of living organisms. In plants, they are usually absorbed from the soil through the roots and are needed for processes such as photosynthesis and making proteins. For example, nitrate ions are used to make amino acids and proteins for growth, and magnesium ions are needed to produce chlorophyll. In animals, essential mineral ions like calcium support bone strength while potassium is involved in nerve and muscle function. Overall, mineral ions are crucial for life because they support vital biological functions in both plants and animals.
