Following observations are made for a plant grown under different conditions. I. Chloride and magnesium in soil + light → green plant II. Chloride and magnesium in soil + dark → etiolated plant III. Magnesium + light → green plant IV. Intermittent light flashes + chloride → etiolated plant From the above observations, it can be concluded that the factors necessary for green colour in plants are
Solution
Observation III shows that magnesium + continuous light alone is sufficient to produce a green plant (chloride is not required in this case), while observation IV shows that chloride with only intermittent light flashes fails to produce greening
