2 Aristotle 384 BC Classified organisms as either plants or animals

6 * * Archaea Please draw this diagram on the backside of your notes sheet. Draw a box around the three domains.

7 Kingdom Monera or Eubacteria Single celled Prokaryotic Make or absorb food Cell wall –peptidoglycan

8 Kingdom Archaea Single celled Prokaryotic Make or absorb food DNA –Similar to Eukaryotic Cell wall –Pseudopeptidoglycan or protein only Live in extreme environments

9 Kingdom Protista Single celled Eukaryotic Ingest or produce food No tissues or organs Animal like— consumers Plant like—producers Fungus like-- decomposers

10 Kingdom Fungi Multicellular Eukaryotic Cell wall –Chitin Absorb food by breaking it down with enzymes –This is why we call them decomposers

11 Kingdom Plantae Multicellular Eukaryotic Cell wall –Cellulose Produce food –Photosynthesis Angiosperms: flowering plants Conifers: cone bearing

12 Kingdom Plantae Vascular Grow tall They have distinctive body forms Tube like cells Can transport water to the leaves Large roots Ex: flowers, trees Non-Vascular Do not grow off the ground Do not have a water vascular system to transport water No roots Ex: moss, lichen

13 Kingdom Animalia Multicellular Eukaryotic No cell wall Ingest food Motile
