- 2. 4 PHYLA: 1. Sarcodina (Amoeba) 2. Ciliophora (Paramecium) 3. Sporozoa (Plasmodium) 4. Mastigophora / Zoomastigina (Trichonympha & Trypanosomiasis)
- 4. Phylum Sarcodina Reproduction: asexual Locomotion: pseudopods (false feet) Movement occurs by cytoplasmic streaming extensions or projections of cytoplasm (projections = pseudopods) Nutrition: phagocytosis – heterotrophs Other information: Cytoplasmic streaming Example: Amoeba
- 7. Phylum Ciliophora Reproduction: asexual & sexual Locomotion: cilia Nutrition: Cilia used to sweep food into “mouth” – heterotrophs Other information: Trichocysts – for defense Example: Paramecium
- 8. Phylum Ciliophora: PARAMECIUM 2 Nuclei Macronucleus controls cell activities Micronucleus is involved in reproduction
- 10. Phylum Sporozoa Reproduction: Asexual & sexual (spores) Locomotion: Non motile = rely on vector or body fluids of host of movement Nutrition: All parasitic – heterotrophs Other information: Need host for nutrition Example: Plasmodium
- 11. PLASMODIUM LIFE CYCLE Vectors (mosquitos) transmit plasmodium from 1 host to another – the only way plasmodium can move Causes malaria in humans – humans are the host Have a spore-like stage in life cycle Do not copy
- 12. Mastigophora / Zoomastigina (Trichonympha & Trypanosomiasis)
- 13. Mastigophora / Zoomastigina • Reproduction: asexual • Locomotion: Flagella • Nutrition: Heterotrophs – most are parasites • Other information: cause disease in humans • Examples: Trichonympha & Trypanosomiasis
- 14. Kingdom Protista Drawings 2. Paramecium – Draw a labelled diagram of Paramecium – Label: macronucleus, micronucleus, food vacuole, contractile vacuole, cilia, trichocysts and gullet
- 15. Kingdom Protista Drawings 3. Amoeba • Draw a labelled diagram of an amoeba • Label: pseudopod, food vacuole, nucleus and contractile vacuole • What is the function of each part? • Explain the following terms: ectoplasm, endoplasm, phagocytosis and cytoplasmic streaming
