The document details changes observed in apples and bananas stored at various temperatures over two days. At room temperature (20°C), apples changed from red to yellowish, while bananas developed dark spots; at 10°C, apples remained green outside with slight internal blue discoloration, and bananas turned darker. Iodine staining indicated starch presence, with minor variations in conversion to sugar across the fruit specimens analyzed.
