why do plants need magnesium for sunlight absorb
Magnesium is one of the most essential minerals for all green parts of a plant because it is used to make chlorophyll, the green pigment in plants that turns water, air, and sunlight into food for the plant. Magnesium is the central atom that the chlorophyll molecule is made around.Without magnesium, plants just can't make chlorophyll, and without chlorophyll, plants slowly die. Look at the diagram of a chlorophyll molecule at right.It may look like confusing gibberish to you, but right in the middle you see a magnesium atom (Mg) surrounded by four nitrogen atoms (N).ithout magnesium, plants just can't make chlorophyll, and without chlorophyll, plants slowly die.
