Describe the procedure, observation, and explanation for testing non-germinating maize seeds for starch using iodine solution.

Here is the procedure, observation/result, and explanation for the starch test using the filtrate from non-germinating maize seeds: A. Test for Starch Procedure: 1. Crush five non-germinating maize seeds in a mortar using a pestle. 2. Add approximately 10 ml of distilled water to the crushed maize seeds in the mortar and stir thoroughly. 3. Filter the mixture using a filter funnel and filter paper into a clean test tube or beaker to obtain the maize seed filtrate. 4. Pour about 2 ml of the obtained filtrate into a clean test tube. 5. Add 2-3 drops of iodine solution to the test tube containing the filtrate. 6. Gently shake the test tube and observe any color change. Observation / Result: The maize seed filtrate turns blue-black or dark blue* upon the addition of iodine solution. Explanation of results: Iodine solution is a chemical indicator used to detect the presence of starch*. Non-germinating maize seeds store a significant amount of starch* in their endosperm as a primary food reserve. When the maize seeds are crushed and filtered, starch granules are released into the filtrate. The blue-black* color change observed indicates a positive test for starch, confirming its presence in the non-germinating maize seed filtrate.
