A scientist follows this procedure to test whether plants
have been performing photosynthesis.
What results will the scientist most likely obtain when
placing drops of the indicator on the leaves?
1. Place Plant X in a dark closet and Plant Y on a sunny
windowsill
2. Wait several days, then remove a leaf from each plant.
3. Boil leaves in alcohol to remove the chlorophyll.
4. Add a chemical indicator that detects sugars. (Dark purple =
sugars are present, dark orange = sugars are not present)
O Plant X: dark purple
Plant Y: dark purple
O Plant X: dark orange
Plant Y: dark purple
O Plant X: dark orange
Plant Y: dark orange
O Plant X: dark purple
Plant Y: dark orange
