A scientist 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
