2.21 understand that plants require mineral ions for growth and that magnesium ions are needed for chlorophyll and nitrate ions are needed for amino acids

As well as water and sunlight, plants require mineral ions to grow. Different mineral ions do different things, two key examples of this are that: magnesium ions are needed for chlorophyll; nitrate ions are needed for amino acids. You simply need to learn this.

    id add this:nitrate - for making amino acids, which are needed to make proteins
    magnesium - for making chlorophyll
    If a plant does not get enough minerals, its growth will be poor. It will suffer from deficiency symptoms:
    deficient in nitrate - it will suffer from stunted growth
    deficient in magnesium - its leaves will turn yellow
