Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What does the plant need magnesium for?
A
For the production of chlorophyll
B
For the production of amino acids
C
For the production of glucose
D
For the production of starch
Explanation: 

Detailed explanation-1: -Magnesium (Mg) is an essential nutrient for a wide array of fundamental physiological and biochemical processes in plants. It largely involves chlorophyll synthesis, production, transportation, and utilization of photoassimilates, enzyme activation, and protein synthesis.

Detailed explanation-2: -Sulfur is necessary for the formation of chlorophyll (the green pigment in plants that converts light to energy). It promotes healthy roots and lowers soil pH. Without enough sulfur, a plant’s new leaves may appear yellowed.

Detailed explanation-3: -Magnesium (Mg), as a central element of the chlorophyll (Chl) molecule and the activator of more than 300 enzymes, plays key roles in various physiological and biochemical processes, including Chl biosynthesis and photosynthesis [1, 2, 3, 4, 5].

Detailed explanation-4: -Photosynthesis takes place in chlorophyll, the green pigment in plants, and magnesium is the central atom of the chlorophyll molecule, with each molecule containing 6.7% magnesium.
