The Six Kingdoms Animals Fungi Plants Archaea Bacteria Protists

How are organism placed into their kingdoms? · Cell type: complex or simple · Their ability to make food · The number of cells in their body

PROTISTA • Biological Junk Drawer • The name Protista means "the very first“ - these organisms have had long independent evolutionary histories • Genome analysis also shows that many of the groups placed in the Protista are not at all closely related to one another

Characteristics • Eukaryotic because they all have nucleus • Multicellular OR Unicellular (mostly found in pond water)

Plant-like Protists Diatoms, Dinoflagellates, Eugelnoids, Algae • Make their own food by photosynthesis • Some consume other organisms in the absence of light • Some live within other organisms as symbionts

Animal-like Protists Amoebas, Ciliates, Flagellates • Consume other organisms for food • Many are parasites, taking nutrients from the organism in which they live in • Ex. Plasmodium living in the liver and red blood cells and causes malaria

Fungus-like Protists Slime molds, Water molds • Absorb nutrients from living and dead organisms, and wastes • Produce spores

Reproduction • Asexual - Methods: Binary Fission, Producing spores • Sexual - Method: Meiosis • Both - Method: Conjugation
