Virus |
Virus is the tiniest microorganism. It can be
found living in some bacteria, fungi, protozoa, animals, plants and humans.
Viruses are not
alive, so they do not have a need for food like living organisms. Viruses do
not have an organized cell structure. They are so light that they can float in
the air or water, be passed on to other organisms if touched, and fit anywhere.
The virus injects its own DNA structure into healthy cells where new virus
cells grow.
There are an example of viruses :
