Unicellular Eukaryotes - Protists (Euglena, Amoeba and Paramecium)
2
I Have In-Depth Notes With Pictures (Including Reproduction) on My Website Under “Class Notes”
3
Very Corny Protist Song
4
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
5
Euglena in Motion
6
Euglena at 1000x
7
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)
8
Amoeba Feeding
9
Paramecium Cilia for movement Heterotrophic Oral Groove for feeding
Contractile vacuole removes excess water Has nucleus Asexual or sexual
10
Paramecium
11
