NEET BIOLOGY

Detailed explanation-1: -Thus, magnesium is an important structural component of chlorophyll molecules. The iron is an essential micronutrient for plants. It is required for synthesis of chlorophyll and has several other functions also. Plants also require an exposure to light in order to synthesize chlorophyll.

Detailed explanation-2: -Magnesium is the central core of the chlorophyll molecule in plant tissue. Thus, if Mg is deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems.

Detailed explanation-3: -Magnesium is one of thirteen mineral nutrients that come from soil, and when dissolved in water, is absorbed through the plant’s roots. Sometimes there are not enough mineral nutrients in soil and it is necessary to fertilize in order to replenish these elements and provide additional magnesium for plants.

Detailed explanation-4: -Plant roots absorb mineral salts including nitrates needed for healthy growth. For healthy growth plants need mineral ions including:-Nitrate for producing amino acids which are then used to form proteins.-Magnesium which is needed for chlorophyll production.

Detailed explanation-5: -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.
