When preparing a plant for an experiment to investigate starch production, why is the plant first placed in darkness for 2-3 days?
1 )
To deplete the plant’s stored energy reserves and make it more responsive to light
To prevent photosynthesis and ensure any starch present is used up by the plant
3 )
To stimulate the production of chlorophyll and increase photosynthetic capacity
4 )
To synchronize the plant’s biological clock with the experimental conditions
