Answers
Answer:
Yes!! It's possible to perform photosynthesis in the absence of light.
This process is call light - independent reaction or Calvin Cycle or dark reactions.
It is possible with the help of the enzyme called RuBisCO. It uses the newly formed NADPH. It produces 3 - carbon compound which later combine to form sucrose and starch.
Explanation:
The above pic depicts the working of Calvin cycle.
This cycle helps in the fixation of carbon.
The 3 carbon compound combines with other compound to form carbohydrates and lipids.
This is used by plants for building up of cellulose, cell membranes. The energy of the plant is passed to animal through food chain.
