Protozoa
Protozoa, also know as protoctista, are like our own body cells. They are single celled organisms with a nucleus and a cell membrane. These can also be known as eukaryotes. Eukaryotes are ten times the size of Prokaryote cells. They are more complex, and larger organisms. Protozoans are generally too small to be seen by the naked eye, but can be seen clearly under a micro-scope. http://www.sciencedaily.com/articles/p/protozoa.htm
Protozoans can cause illness and diseases such as Malaria, Sleeping sickness, and dysentery. Http://www.biotopics.co.uk/newgcse/mircobesanddisease.html

Viruses contain a core of nucleic acid (DNA or RNA) and are surrounded by protein. Viruses are not considered to be living organisms. They are inactive when living outside a cell. Viruses make copies of themselves, then break out and infect others. Viruses cannot be treat with anti-biotics. Viruses are too
