Question

Given below is the diagram of an experimental set-up :

(d) Would you take any step before starting the experiment? Describe this step and explain its necessity.

Answer 1

Yes, we have to take a step before starting the experiment. The plant used for an experiment on photosynthesis should initially be placed in the dark for 24 to 48 hours to destarch the leaves. During this period, all the stored starch will be used up by the leaves as the plant won’t be carrying out any photosynthesis.
