Why do we have to boil leaf in water what happens if this step is not done?
Boiling a leaf in water is a crucial step in experiments such as testing for starch because it helps to break down the cell walls, making the starch more accessible for detection. If this step is skipped, the starch present in the leaf may not dissolve properly, leading to inaccurate or inconclusive results when testing for its presence. Additionally, boiling denatures enzymes that could interfere with the test.
