  1. Magnesium
  2. Nitrogen
  3. Potassium
  4. Manganese

hintHint:

The chemical element that is represented by the letter K.

The correct answer is: Potassium


    • Potassium is absent in chlorophyll
    • Potassium is associated with the movement of water, nutrients, and carbohydrates across plant tissues
    • Iron is required for chlorophyll synthesis and for preserving the structure and function of the chloroplasts
    • Manganese stimulates the enzyme for photosynthesis and nitrogen metabolism
    • Chlorophyll contains a magnesium ion encased in a large chlorine ring framework
