2 Objective Compare the structures and functions of the following single- celled organisms: Euglena Amoeba Paramecium Volvox

3 Essential Question: What are the characteristics of the following single-celled organisms? Euglena Amoeba Paramecium Volvox

4 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 Euglena

5

6 Environment: Fresh and salt water Movement: Cytoplasmic Streaming –Changing shape Food: heterotrophic –They surround their prey and engulf it with a Pseudopodium- (false foot) Reproduction: asexual Additional Information: Changes shape Amoeba

7 Amoeba Eating Paramecium

8 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 Paramecium

9

10 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. Volvox
