Basic Structure of Protists

• Uni- or multicellular
• Algae can photosynthesis as they have chloroplasts
• Locomotary systems occur

  e.g pseudopodia in Amoeba (false feet)

  cillia (Paramecium)

  Flagella (Euglena and dinoflagellates)
• Protozoa ingest their foot by phagocytosis
• Cell wall composition varies in plant-like protists; green algae have cell walls of cellulose while diatoms gave cell walls of silica that give a shiny appearance
