Protista
Kingdom Protista
Protist: Eukaryotic organisms (usually unicellular) that is not a fungus, plant or animal * 90% are unicellular organisms * Split based on locomotion * The kingdom divides into three main sections being: animal-like, plant-like and fungus-like. Then they are split based on their form of locomotion. * They live in moist environments -> aquatic environments or blood. * Even though they are single-celled, they are MUCH larger than Archae and bacteria (refer back to the lab and green phyla). They are also diversely shaped, have different colours and interesting to watch! * Very difficult to analyze these organisms without help from a microscope
Characteristics of Protists * Categorized as Protists because they do not fit into any other kingdom, opposed to sharing similar characteristics like other kingdoms do (ex. all plants are autotrophic) * Some algae are multicellular and this is what we study about in chp 3…algae -> plants * Three different categories are based on their method of obtaining nutrition
Animal- Like= Protozoa * 4 different phylum: ciliophora (ciliates), zoomastigina (flagellates), sporozoa, sarcodina * Heterotrophic and some are parasites (sporozoa) * Parasites: Organisms that benefit from living in or on other organisms at the expense of that organism * Phyla based on locomotion
Plant-like= Algae * 6 phyla based on their chloroplasts and pigments they have * Autotrophic: make their own food by photosynthesis * Some consume other organisms in the presence of light & other are symbiotic (live in other organisms- not necessarily beneficial for both parties) * Carry pigments in their chloroplast to carry out photosynthesis * Most common is chlorophyll which is typically green in colour * Lack leaves, stems, roots and water-conducting tissue
Fungus-like= Moulds * Absorb nutrients from living or death organisms * Some slime
