  1. ObjectiveCompare the structures and functions of the following single-celled organisms: Euglena Amoeba Paramecium Volvox

  2. Essential Question: What are the characteristics of the following single-celled organisms?EuglenaAmoebaParameciumVolvox

  3. Euglena • Environment: fresh and salt water • Movement: flagella (tail-like) • Food: • Heterotrophic- engulfs full cell and absorb them. • Autotrophic- make their own food using chlorophyll. • Reproduction: asexual • Additional Organelle: • Eye spot- senses light and guides Euglena in its direction

  4. Euglena http://www.youtube.com/watch?v=ZHZZKwrYm4g

  5. Amoeba • Environment: Fresh and salt water • Movement: Cytoplasmic Streaming • Changing shape • Food: heterotrophic • They surround their prey and engulf itwith a Pseudopodium- (false foot) • Reproduction: asexual • Additional Information:Changes shape

  6. Amoeba Eating Paramecium http://www.youtube.com/watch?v=pvOz4V699gk

  7. Paramecium • Environment: Fresh water • Movement: Cilia (hair-like) • Bend and straighten helping propel organism through water. • Food: Heterotrophic • Uses cilia to sweep the food into the cell. • Reproduction: sexual and asexual • Additional Info: Most complex and specialized

  8. Paramecium http://www.youtube.com/watch?v=l9ymaSzcsdY

  9. Volvox • Environment: freshwater, unicellular organism called ciliates living in a colony together • Movement: Each cell in the colony has 2 flagella • Eyespots: sense and guide towards light • Food: • Heterotrophic • Eat algae • Autotrophic • makes its food through photosynthesis • Reproduction: asexual and sexual • daughter colonies (offspring) mature and the Volvox bursts open to release them.
