boiled kelp

Before scrolling down for the pictures, does something seem different about this first picture as compared to normal plant cells?

The correct answer to that is the color! What caught my eye was how the chloroplasts changed from a green to a dull and brownish color.

As seen on the top picture, the normal kelp has cells with a green color mainly because the chloroplasts are still active. When chloroplasts are boiled however, enzymes inside them are denatured, thus causing them to lose their shape and function.

 Just remember that when you boil vegetables or plants, it will be less likely for them to be able to conduct photosynthesis well because they won't be able to obtain light energies as efficiently as before.
