Bacteria



Bacteria live almost everywhere, even where other forms of life canít. The only placesí
where they canít survive is in sanitized places. Some bacteria need oxygen to survive, and
others donít need any. Also some can survive with both, but some canít survive with
oxygen. They protect themselves by forming a thick cell membrane inside the old one.


Bacteria get food by feeding off of other tiny organisms and by making food. They make
their food by using the sunlight, water, and carbon dioxide. They move by attachments off
their body, which is mainly, called flagellas. Theyíre like a tails or antennas. Bacteria
reproduces when one of them become to large. It then divides into two.


Bacteria can also harm humans, plants, and animals. They harm are bodies by coming through
a opening in are body and then finding a cell. When they take over a cell they reproduce
and kill it. Without a cell to take over they would die. Some diseases that bacteria makes
are cholera, gonorrhea, leprosy, pneumonia, syphilis, tuberculosis, typhoid fever, and
whooping cough.
