Protists

Protists are single-celled eukaryotes, which means they contain a nucleus and other organelles within the cell.  Some protists form colonies that can appear to resemble a multi-cellular organism, such as slime moulds.  Other examples of protists are red and green algae, amoebeas, and several plant pathogens including Phytophthora infestans, which causes the potato blight that lead to the Irish Potato Famine.
