==Introduction==
 +
 +
All protozoa are unicellular eukaryotic organisms which store their genetic information in chromosomes in a nuclear envelope. Protozoa are classified depending on their structure and life cycle. This reflects the similarities of the diseases which they cause.
 +
 +
Protozoa usually range from 10μ-50μ but can grow up to 1mm. Thus, they are usually observed and classified using a microscope.
 +
 +
Protozoa multiply sexually, asexually and can also use a combination of both, for example, the coccidia class. Replication can be by binary or multiple fission. Different protozoa use different forms of motility, either flagella, cilia, pseudopodia or gliding.
