Question

A student sets up an experiment on photosynthesis as follow: He takes soda water in a glass tumbler and add a chlorophyll extracts into the contents and keeps the tumbler exposed sunlight hoping that he has provided necessary ingredient for photosynthesis to proceed (viz, $C{O}_2,H_{2}O$, chlorophyll and light)
What do you think what will happen after, say few hours of exposure of light?

• A. Photosynthesis will take place and glucose will produced
• B. Photosynthesis will take place and starch will be produced which will turn the mixture turbid
• C. Photosynthesis will not take place because $C{O}_2$ dissolved in soda water escapes into the atmosphere
• D. Photosynthesis will not take place because intact chloroplasts are needed for the process

Answer 1

The correct option is D Photosynthesis will not take place because intact chloroplasts are needed for the process

Photosynthesis is a process, in which green plants manufacture their own food with help of carbon dioxide and water in presence of sunlight and takes place in the chloroplasts.
Chloroplast contains all the proteins and enzymes necessary to carry out photosynthesis in the grana (stacked thylakoids) or in the stroma (fluid inside inner membrane).
In the question, as the chloroplasts are not added as an ingredient, photosynthesis does not take place.
