Question

Identify the metal x present in chlorophyll and write the reaction of this metal with ${n_2}$.

Answer 1

Chlorophyll's primary function in a plant is to absorb light, most commonly sunlight. Light energy is delivered to two different types of energy-storing molecules. Photosynthesis is the process by which a plant converts carbon dioxide (a gas received from the air) and water into glucose, some sugar.

Complete answer:
Magnesium is the metal-X found in chlorophyll.
Magnesium oxide is formed when magnesium combines with oxygen gas.
\ [2Mg (Magnesium) + {O_2} (Oxygen) \to 2MgO](Magnesium oxide)
Magnesium nitride is formed when magnesium combines with nitrogen gas.
$M{g_3} {N_2} \to 3Mg + {N_2}$(Magnesium +Nitrogen)
Chlorophyll's Function -
-Chlorophyll absorbs the light required for photosynthesis to occur.
Chlorophyll is required for photosynthesis, the process by which plants receive energy from the sun. Chlorophyll molecules are organized in and around photosystems contained in chloroplast thylakoid membranes. This pair has an effect on chlorophylls' final function, charge separation, which results in biosynthesis. Chlorophylls absorb the lightest in the blue and red portions of the electromagnetic spectrum. On the other hand, it is a poor absorber of green and near-green light. Thus, chlorophyll-containing tissues appear green because green light is less absorbed when diffusively reflected by structures such as cell walls. Chlorophyll a and b are found in the photosystems of green plants. Joseph Bienaimé Caventou and Pierre Joseph Pelletier isolated and identified chlorophyll for the first time in 1817. Magnesium was first detected in live tissue in 1906, when it was identified in chlorophyll.

Note:
Chlorophyll molecules are organized in and around photosystems contained in chloroplast thylakoid membranes. [16] Chlorophyll performs three functions in these complexes. The vast bulk of chlorophyll (up to several hundred molecules per photosystem) is responsible for light absorption.
