Question
Why is it important to destarch a plant before an experiment?
✓
Answer
Destarching removes any starch already present in the leaves, ensuring that any starch detected after the experiment is solely due to the experimental conditions.This ensures accurate results by providing a clear baseline, allowing you to observe and measure new starch production without interference from pre-existing starch.
