Starch is manufactured in the green leaves of plants from excess glucose produced during photosynthesis and serves the plant as a reserve food supply.
What is the function of starch?
The main function of starch is as way to store energy for plants. Starch is a source of sugar in an animal's diet. Animals break down starch using amylase, an enzyme found in saliva and the pancreas that breaks down starch to get energy.
What is the function of the starch in the leaf?
Starch is a white and powdery substance. It houses glucose, which plants use for food. The presence of starch in a leaf is reliable evidence of photosynthesis. That's because starch formation requires photosynthesis.

Summary. Corn flour can be used to make breads and pastries, whereas cornstarch is used as a thickening agent.
What is difference between flour and starch?
