Chlorophyll contains a single atom of magnesium at its centre
Photosynthesis is a naturally occurring process that takes place in plants, algae and even some forms of bacteria. They utlize the sun’s energy to convert CO2 into carbohydrates. Photosynthesis is an essential part of life on Earth. During photosynthesis CO2 expelled by animals, humans and burning hydrocarbons is absorbed and oxygen is released. There are some forms of bacteria that perform anoxygenic photosynthesis and no oxygen is released. Photosynthesis the counterpart of cellular respiration.

Chlorophyll is essential for photosynthesis. It serves two primary functions in the photo systems. The major function of chlorophyll is to absorb light and transfer that light energy into chemical energy. There is more than one type of chlorophyll, each type plays a different role and has a unique chemical structure. Note that providing soluble silicon to plants results in increased concentration of chlorophyll in leaf tissues, resulting in enhanced metabolism resulting from increased use of available light energy.
This tutorial introduces chemical compounds
is the molecule that absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water. This process is known as and is the basis for sustaining the life processes of all plants. Since animals and humans obtain their food supply by eating plants, photosynthesis can be said to be the source of our life also.
Plant Nutrition and Magnesium - TIMAB Magnesium
This metal plays a decisive role in photosynthesis. Magnesium is the central atom of the chlorophyll molecule, very much like the iron atom in the rather similarly structured haemoglobine (red bood pigment). Magnesium also fulfills many other functions in the organism of plants, e.g. in the activation of enzymes, the formation of proteins, DNA and RNA, carbohydrates, fats and vitamins, in phospate transportation, the carbohydrate metabolism and the transmission of energy. Inside a plant, magnesium is most highly concentrated in the areas where the plant grows. Calcium, though chemically rather similar, is most highly concentrated in the oldest parts of a plant. Magnesium is relatively mobile within plants.
