Kingdom Protista

Members of the Kingdom Protista are an unusual group of organisms that were put together because they don't really seem to belong to any other group. Some protists look or act like plants, others look and act like animals, but they're not!

In some ways, the Kingdom Protista is home for the "leftover" organisms that couldn't be classified elsewhere. You might not think a tiny one-celled amoeba has much in common with a giant sea kelp, but they're both members of this kingdom.
