Question

Solarisation is a process in which
A) Sugars are formed with the help of solar energy
B) Chlorophyll is formed
C) Destruction of chlorophyll and ultimate death of protoplasmic compounds occurs.
D) None of the above.

Answer 1

Hint: Solarisation is the inhibition of photosynthesis at a very high intensity of light. During the process of photosynthesis, chlorophyll pigments trap the sunlight. But later they get destroyed due to the exposure in high intensity light.

Complete answer:
Option A) Sugars are formed with the help of solar energy: During the process of solarization, sugars are not formed. Sugars are produced with the help of solar energy by all green plants and photosynthetic bacteria.
Option B) Chlorophyll is formed: Chlorophyll is the molecule that absorbs sunlight and uses its energy. Chlorophyll is not formed by solarization.
Option C) Destruction of chlorophyll and ultimate death of protoplasmic compounds occurs: During the process of photosynthesis chlorophyll pigments trap the sunlight but they get destroyed due to exposure to light of higher intensity. Chlorophyll gets destroyed within a few durations of exposure to light.
Option D) none of the above: This option is not correct because option C is correct. Solarization is the process of destruction of chlorophyll and the ultimate death of protoplasmic compounds.

Correct answer is option C) Destruction of chlorophyll and ultimate death of protoplasmic compounds occurs.

Note:
Solarisation is the process of destruction of chlorophyll and ultimate death of protoplasmic compounds occurs. During the process of photosynthesis chlorophyll traps the sunlight to synthesize carbohydrates from \[CO_2\] and water. But these chlorophylls get destroyed very quickly due to the exposure to very intensive light. The destruction of chlorophyll when they are exposed to sunlight of high intensity is called solarization.
