Question

Which metal ion is a constituent of chlorophyll?
a. Iron
b. Copper
c. Magnesium
d. Zinc

Answer 1

Chlorophyll (which is also called chlorophyll) is any of several related green pigments which are found in the mesosomes of cyanobacteria. This green pigment is also found in the chloroplasts of algae and plants. People say that the word Chlorophyll is derived from the Greek words khloros (which means "pale green") and phyllon (which means "leaf"). We know that one of the important elements in the process of photosynthesis is Chlorophyll.

Complete answer:
Chlorophyll plays an important role in the process of photosynthesis since it allows the plants to absorb energy from the light given away by the sun.
- The element Magnesium is an essential component of the green pigment present in the plants called chlorophyll. The Chlorophyll is the green photosynthetic pigments that are classified into five types.

- They are chlorophyll a, b, c, d, and d and e which occur in the chloroplasts of higher plants. On brief research, we can say that the molecular formula of chlorophyll a, b, c, and d are,
${C_{55}}{H_{70}}{O_6}{N_4}Mg$,
${C_{35}}{H_{32}}{O_5}{N_4}Mg$,
${C_{54}}{H_{70}}{O_6}{N_4}Mg$
The type Chlorophyll-e is a rare type of Chlorophyll that is found in some golden algae.

- The elements like Copper, iron, Zinc are not present in chlorophyll, however, we can find them in different parts of the plant. Copper and zinc are not found in plants however, it absorbs it. Iron is found in plastids of the plants.

Hence, the correct answer is option (C).

Note: It is said that this green pigment called Chlorophylls make the plants absorb light most strongly in the blue section of the spectrum of electromagnet as well as the red portion. On the other hand, it is a meager absorber in the portions of green and near-green colors of the spectrum, when it gets reflects, manufacturing the green color of tissues which are containing chlorophyll.
