  1. Kingdom Protista The Miscellaneous Category

  2. Animal like (4) Plant like (6) Protists Paramecium Fungi like (1) volvox Hartmanella vermiformis Protozoan Protists: • A varied kingdom with 11 phyla that have little in common! • Incredible biodiversity  occupying almost every niche and habitat!

  3. Features • Most are unicellular. Some form colonies of identical cells. A few are multi-cellular but don’t form tissue (algae) • Cells are eukaryotic – membrane- bound nucleus, most have vacuoles & mitochondria, some have chloroplasts. • Cell reproduce asexually through binary fission. Some exchange DNA via conjugation • Cells thrive in moist environments (fresh or salt water, animal fluids & very damp terrestrial environment)

  5. Spirogyra diatoms Polysiphonia Red Algae Plant-Like Protists • Contain chlorophyll  can photosynthesize (autotrophs) • But… during dark periods, can engulf nutrients from their environment (heterotrophs) • Most have 2 flagella for locomotion • Examples: species of green, brown and red algae

  6. Amoeba proteus Arcella, a common shelled amoeba  Paramecium Animal-Like Protists • All are heterotrophs  can gather nutrients by engulfing their food or by absorbing it through their membranes • Classified by type of locomotion (cilia and flagella) • Reproduce by binary fission • Examples: • Amoeba (feed by phagocytosis • Paramecium (feeds via an oral groove)

  7. Importance of Protists: • Provide the critical base to most food webs Algae • Primary food producers in aquatic food chains • Provide 80% of the world’s oxygen • Used by humans as food, fertilizers, drugs, cosmetics, etc…
