Kingdoms in the Beginning When There Were Two Kingdoms in the Beginning

Two Kingdoms Aristotle (Remember him?) – Plants and Animals How were these divided? The Microscope! How did this change the classification and the two kingdom system? Discovery of Euglena (Which kingdom?) Moved AND was photosynthetic. Now what? Better microscopes were created Found unicellular organisms without a nucleus (what are these called?) What kingdom did this create? What about organisms that were non-motile, absorptive heterotrophs? - What kingdom did this create?

The Five Kingdoms

Kingdom Monera -Prokaryotic -Unicellular -No sense organs Divided into two subkingdoms (in a five kingdom system) Bacteria Absorptive heterotroph Motile Blue-green algae Photosynthetic Non-motile

Kingdom Protista -Eukaryotic, no sense organs Photosynthetic Protista Uni/multi celluar Motile/Non motile Example: Rockweed Absorptive Protista Heterotroph Uni/multi cellular Example: Slime mould Ingestive Protista Unicellular Motile Example: Paramecium

Kingdom Fungi Eukaryotic Multicellular, few unicellular Absorptive heterotroph Non motile ** One exception is a lichen, which lives symbiotically with a photosynthetic blue green algae. Example: Mushroom

Kingdom Plantae Eukaryotic Photosynthetic Multicellular Non motile Non-vascular Example: Moss Vascular - Example: Pine Tree

Kingdom Animalia Eukaryotic - Ingestive heterotroph Multicellular Motile Simple Asymmetry Example: Sponge Complex Symmetry Bilateral. Example: Fox Radial. Example: Starfish
