Question

What is the component of chlorophyll?
A. Mg
B. Mn
C. Zn
D. Fe

Answer 1

Hint: Chlorophyll is specially present in autotrophic organisms like in plant cells to perform the process of photosynthesis. It traps the sunlight to ensure the food making process of plants and utilize the availability of sunlight.

Complete Answer:
- Chlorophyll is the main component of the plant cell, it is the green coloured pigment that present in the cell organelle names as plastid and it is specially present on the thylakoids membrane inside the plastid.
- We chemically study the chemical structure of the chlorophyll then we came to know that the chemical formula of chlorophyll will be $C_{ 55}H_{72}O_{5}N_{4}Mg$ . This will be the chemical structure of chlorophyll.
- From the chemical structure of the chlorophyll we came to know that the chlorophyll has a hydrocarbon chain centrally located with Magnesium (Mg). Along with it have a porphyria ring in which Mg ion is centrally located.
- The types of the chlorophyll changed according to the side chain that was present on the porphyrin ring. Here central ion magnesium and the porphyria ring is the main root of the structure and the rest character gets changed according to the nature of the side chain that is present on the ring.
Here we can clearly see that magnesium is the component of chlorophyll.

Hence, the correct answer is option A.

Note: Chlorophyll is of mainly two types chlorophyll a and chlorophyll b. If methyl group is present as the side chain with the porphyria ring then it should be chlorophyll a. If the aldehyde group is present as the side chain then it will be the chlorophyll b.
