Question

Which of the following equations is the summary of photosynthesis?

• A. $6{\mathrm{CO}}_2+12{\mathrm{H}}_2\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{O}}_2+6{\mathrm{H}}_2\mathrm{O}$
• B. $6{\mathrm{CO}}_2+{\mathrm{H}}_2\mathrm{O}+\mathrm{Sunlight}\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+{\mathrm{O}}_2+6{\mathrm{H}}_2\mathrm{O}$
• C. $6{\mathrm{CO}}_2+12{\mathrm{H}}_2\mathrm{O}+\mathrm{Chlorophyll}+\mathrm{Sunlight}\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{O}}_2+6{\mathrm{H}}_2\mathrm{O}$
• D. $6{\mathrm{CO}}_2+12{\mathrm{H}}_2\mathrm{O}+\mathrm{Chlorophyll}+\mathrm{Sunlight}\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{CO}}_2+6{\mathrm{H}}_2\mathrm{O}$

Answer 1

The correct option is C

$6{\mathrm{CO}}_2+12{\mathrm{H}}_2\mathrm{O}+\mathrm{Chlorophyll}+\mathrm{Sunlight}\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{O}}_2+6{\mathrm{H}}_2\mathrm{O}$

The correct option is C.

The explanation for the correct option:

1. Photosynthesis refers to the process by which plants synthesize their own food in the form of glucose by using Carbon dioxide and water in the presence of sunlight.
2. The plant produces Glucose and Oxygen as products of this reaction.
3. It is done inside the chlorophyll pigment.
4. Without chlorophyll pigment, photosynthesis will not proceed.
5. Hence the correct option is C.

The explanation for the incorrect options:

Option A:

1. This chemical reaction does not involve Sunlight or Chlorophyll pigment.
2. Without these both, photosynthesis cannot happen.
3. Hence this is an incorrect option.

Option B:

1. This chemical reaction does involve Sunlight and other factors but does not involve Chlorophyll pigment.
2. Without chlorophyll pigment, photosynthesis will not proceed.
3. Hence this is an incorrect option.

Option D:

1. This chemical reaction does involve Sunlight, Chlorophyll pigment, and other factors.
2. But photosynthesis does not liberate CO2 as a byproduct.
3. Hence this is an incorrect option.

Final answer: $6{\mathrm{CO}}_2+12{\mathrm{H}}_2\mathrm{O}+\mathrm{Chlorophyll}+\mathrm{Sunlight}\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+6{\mathrm{O}}_2+6{\mathrm{H}}_2\mathrm{O}$ this equation is the summary of Photosynthesis.
