Pond Diversity Classify these organisms
Classification Task In the next series of slides, you will be shown pictures of pond organisms that should look familiar. Use your key to classify each of these to: Domain Kingdom Phylum Class (for Arthropods and Vertebrates)
Mallard Duck Features: Feathers made of keratin. Jaws with keratin beak. Bony skeleton.
Diatoms Single-celled organisms with nuclei Silica shells Brown photosynthetic pigment.
Daphnia (Water Flea) Multicellular organism about 1mm long. Specialized organs, jointed appendages. Exoskeleton made of chitin, with calcium carbonate Feathery gills
Hydra Soft-bodied, multicellular, heterotrophic organism. Uses tentacles to catch prey. Radial symmetry. Specialized tissues, but no specialized organs.
Chlorella Tiny single-celled autotrophs with a nucleus. Cell walls made of cellulose. Forms symbiotic relationships with animals such as Hydra.
Euglena Single-celled, motile organism. Uses chloroplasts to synthesize food. Also eats bacteria.
Water Fern Multicellular autotroph. Contains vascular tissue. Reproduces using spores; does not make seeds.
Stentor Single-celled eukaryote. “Mouth” end covered with tiny cillia that sweep the water for food, such as algae, diatoms.
Rough-skinned Newt Bony skeleton, jaws. Skin is soft, no scales. Lays jelly-like eggs in ponds.
Dragonfly External skeleton made of chitin Segmented body Six legs Jointed appendages.
Spirogyra Single-celled autotrophs that form long, filamentous colonies. Use cholorophyl as a photsynthetic pigment and have cell walls made of cellulose.
Decomposing Bacteria Prokaryotic, single- celled organisms. Responsible for breaking organic compounds into inorganic compounds.
Oregon Ash Multicellular, terrestrial autotroph. Cell walls made of cellulose; uses chlorophyl for photosynthesis. Produces seeds inside of an ovary.
