Detailed explanation-1: -Chlorophyll or leaf green is a porphyrin derivative with magnesium as the central atom and is hence a metal complex dye. It is present in the chloroplasts in all green parts of plants as a mixture of blue green chlorophyll a and yellow green chlorophyll b, and constitutes the catalyst for photosynthesis.

Detailed explanation-2: -It consists of a porphyrin ring which has magnesium ions in the center. The two types of chlorophyll are chlorophyll a and b. Chlorophyll a has a porphyrin ring with the side chain of the methyl group and a phytol chain. Chlorophyll b has a porphyrin ring with the side chain of the aldehyde group and a phytol chain.

Detailed explanation-3: -Not only that, the nutrient element manganese also contributes to the formation of chlorophyll in plants. Chlorophyll becomes the most important component in the process of photosynthesis as a light absorber and uses its energy to produce carbohydrates, CO2 and H2O (Singh et al., 2020).

Detailed explanation-4: -Magnesium is present in the tetrapyrrole ring of chlorophyll in its center. Magnesium is the element that causes plants to be able to convert light into energy. It is an essential component of chlorophyll.

Detailed explanation-5: -Plants require both Fe and Mg for the synthesis of chlorophyll. Therefore, we can tell that calcium is not present in chlorophyll.
