Protista

According to my online source (see site page), "The Protista Kingdom consists of unicellular lifeforms (lifeforms with only one cell) who have a nucleus. The primary difference between protists and monera is that protists are more complex, having a nucleus. Many protists appear to be both plant and animal. Like plants, they are green, and can create their own food. However, like animals, they have moving body parts and are able to move around their environments."
