This is a term used to describe animal-like protists that may be distantly related but share a set of characteristics. Types of Protozoans Protozoans are described and grouped according to their method of __________________. Heterotrophs – ingest small food particles and digest it inside ___________________ containing _________________________ Do not have a ____________________ 4 ways to describe a protozoan: Zooflagellate Amoeba Ciliate Sporozoan Zooflagellates Possess 1 or more whip-like structures called ____________________________ Flagella help with ____________________ of the protist in water Ciliates Ciliates are aquatic protists covered with ____________________ Cilia – ___________________________ __________________that assist protists with movement in water and with gathering food Amoeba No particular body shape Create pseudopods – ____________________ ______________________________________ _____________________ help protist to move and feed on other organisms Intake food through process of ____________________– engulf organism and form food vacuole Sporozoans _________________________ protists Produce spores during reproduction Plant-like Protists Plant-like protists are those that resemble plants because they are _________________________. They contain ____________ and carry out ____________________ Unicellular or multicellular protists Some plant-like protists have ______________ made up of polysaccharides and others do not have cell walls Types: Euglenoids Algae Euglenoid Unicellular Contains ________________ for movement ________________________ during the day – undergoes photosynthesis ________________________ at night – feeds on dead organisms Question: Why can euglenoids not be classified in Kingdom Plantae?
