Conclusion:
Experiments have shown that ultraviolet radiation damages and
kills the cells of living organisms. The experiments performed
in this project alone demonstrate this. We see examples of its
deleterious effects not only in plants and bacteria but in human
beings as well. Skin cancer is an example of this. It is caused
by ultraviolet radiation being absorbed by our skin cells.There
are, however, protective mechanisms in our bodies and in our
environment that function to minimize or prevent the deleterious
effects caused by over exposure of living organisms to
ultraviolet radiation. Pigment, present in the skin of most
human beings, and ozone, present in the stratosphere, both serve
to absorb ultraviolet radiation.
