A plant is destarched by

• adding iodine to it
• boiling it in ethanol
• keeping it in the dark for 48 hours
• using Benedict's reagent

Testing this type of leaf can show that

• carbon dioxide is needed for photosynthesis
• light is needed for photosynthesis
• chlorophyll is needed for photosynthesis
• water is needed for photosynthesis
