Ascientist follows this procedure to test whether plants have been performing photosynthesis. place plant x in a dark closet and plant y on a sunny windowsill. wait several days, then remove a leaf from each plant. boil leaves in alcohol to remove the chlorophyll. add a chemical indicator that detects sugars. (dark purple = sugars are present; dark orange = sugars are not present) what results will the scientist most likely obtain when placing drops of the indicator on the leaves? 1: plant x: dark purple plant y: dark purple 2: plant x: dark orange plant y: dark purple 3: plant x: dark orange plant y: dark orange 4: plant x: dark purple plant y: dark orange
