I Have In-Depth Notes With Pictures (Including Reproduction) on My Website Under “Class Notes” http: //www. wsfcs. k 12. nc. us/dom ain/333
Very Corny Protist Song
Euglena Unicellular (Single-Celled) Autotrophic Photosynthesis (he’s green with chloroplasts) Can also feed (heterotrophic) Contractile vacuole Pumps out excess water (osmoregulation) Help maintain homeostasis Light detection, phototaxis, Flagella for movement Has nucleus Asexual via binary fission
Euglena in Motion
Euglena at 1000 x
Amoeba Pseudopods (“false foot”) for movement and feeding via endocytosis Waste removal via exocytosis Senses prey by chemical agents given off (chemotaxis) Has a nucleus Contractile vacuole for osmoregulation homeostasis Asexual Exact copy of itself (no genetic diversity) Sexual Exchange of genetic material between two amoeba (genetic diversity)
Amoeba Feeding
Paramecium Cilia for movement Heterotrophic Oral Groove for feeding Contractile vacuole removes excess water Has nucleus Asexual or sexual
Paramecium
