The main role of an indicator is to establish the equivalence point when two substance has reached its neutralization process. The purpose of an indicator is to determine how acidic or basic the product or solution is. Indicator solutions work by actually reacting with the components of food that they test for, creating a new substance of a different color. This is a chemical reaction.If the substance that they test for is not present in the food, there will be no reaction, and therefore no color change. The test strips will be more likely to be dark blue or black for Grape, Tomato, Summer squash, Orange Bell pepper as they all contain starch. Color intensity may vary depending on the level of starch found in the samples.

Explanation:
Una de las características que diferencia a las células procariontes de las eucariontes, es que las células eucariontes tienen organelos membranosos como los cloroplastos. Las células eucariontes son más complejas que las celulas procariontes, y tienen organelos rodeados por membranas donde efectúan sus distintas funciones celulares. Las células procariontes no tienen organelos y realizan la mayoría de sus funciones directamente en el citoplasma.
