I heard that magnesium is found in plants. In what form is it found in them ?


Magnesium is the powerhouse behind photosynthesis in plants. Without magnesium, chlorophyll cannot capture sun energy required for photosynthesis.
Magnesium gives leaves their green color. Magnesium in plants is found in the enzymes, in the heart of the chlorophyll molecules.
