- The leaf is boiled in hot water to kill the protoplasm
- The boiled leaf is placed in boiling alcohol to remove chlorophyll
- The leaf without chlorophyll is placed on a white tile and a drop of iodine added
- After a few minutes, the parts of the leaf that contain starch turn the iodine from brown to blue/black.
