Microscopic Fossils Offer Big Clues to Earth's Climate
Members of the Kingdom Protista are the simplest of the eukaryotes.
Protistans are an interesting assemblage of organisms classified for what
they are not. Protistans lack characteristics shared by plants
, but they're not bacteria
Essentially, this Kingdom is home for the "leftover" organisms that couldn't be classified elsewhere!
Protists can be unicellular, multicellular or colonial. Some move around and act like animals, others perform photosynthesis like plants, and still others seem to "think" they're fungi! You might not think a tiny one-celled amoeba has much in common with a giant sea kelp, but they're both members of the protist kingdoms.
