Question

Which metal atom is present in chlorophyll? (A) Cu (C) Mg (DK ​

Answer 1

Answer:

Mg

Explanation:

They are magnesium (Mg) and iron (Fe). They are essential macronutrients for plants. Plants require both Fe and Mg for the synthesis of chlorophyll. Therefore, from what we have discussed above, we can tell that calcium is not present in chlorophyll.

Answer 2

(C) Magnesium

Explanation:

• Chlorophyll or leaf green is a porphyrin derivative with magnesium as the central atom and is hence a metal complex dye.
• Thus chlorophyll contains magnesium as its metallic constituent, the chlorophyll molecule has a porphyrin head with a tetrapyrrolic ring structure and a phytol tail of hydrocarbons.
• Magnesium is present in the head region of the chlorophyll molecule.
