Which PRODUCT of photosynthesis caused the leaf discs to float in this lab?

• Bicarb

• water

• glucose

• oxygen

In which beaker did the leaf discs float faster, and why?

• The water beaker, because plants only need water

• The water beaker, because CO₂ is toxic

• The bicarb beaker, because it provided CO₂

• The bicarb beaker, because it provided O₂ to the beaker
